Satellite-powering technology that was abandoned decades ago has been reinvented to potentially work with traditional power stations to help them convert heat to electricity more efficiently, meaning we would need less fossil fuel to burn for power. A new study in Nano Energy presents a prototype energy converter, which uses graphene instead of metal, making it almost seven times more efficient.

The researchers behind the study, led by Prof. Roger Howe at Stanford University, say new materials could reignite the field of thermionic energy conversion, improving the way we produce electricity and reducing the impact the process has on the environment.

Energy is one of the most challenging problems society faces today, with an estimated 1.2 billion people having no access to electricity. Thermal energy is one of the most abundant, cheap and widely used energy sources in the world, but it is harvested using old technology: more than 80 percent of the electricity generated in the US comes from mechanical heat engines and turbines based on the 19th century technology that can only be used in large power stations.

Alternatively, the thermionic energy convertor (TEC) can convert heat to electricity more efficiently without the need for big, expensive equipment through the phenomenon of thermionic emission. TECs were first developed in the 1950s for use in space programs, but scientists had not managed to make TECs efficient enough to apply to industrial electricity production. Now, with modern materials and approaches, it is possible to improve their efficiency significantly.

The TEC is composed of two electrodes, namely the emitter and collector, separated by a small vacuum gap. The researchers tested a prototype TEC made using a single sheet of carbon atoms - graphene - instead of tungsten as the collector material. They found the new material improved the efficiency of the TEC, making it 6.7 times more efficient at converting heat into electricity at 1000?C

"TEC technology is very exciting. With improvement in the efficiency, we expect to see an enormous market for it," commented lead author Dr. Hongyuan Yuan from Stanford University. "TECs could not only help make power stations more efficient, and therefore have a lower environmental impact, but they could be also applied in distributed systems like solar cells. In the future, we envisage it being possible to generate 1-2 kW of electricity from water boilers, which could partially power your house."

Existing TEC technology faces two obstacles: a high loss of energy at the anode surface, which leads to reduced output voltage, and high electrical barriers against electrons moving in the gap between the collector and the emitter, which results in reduced output current. For the first time, the new prototype tackles both of these problems simultaneously. The findings of the study reveal an electronic efficiency in energy conversion of 9.8 percent - by far the highest efficiency at 1000?C.

The technology is not yet ready for use in power stations or people's homes - the prototype works in a vacuum chamber but not in a normal setting. The researchers are now working on a vacuum packaged TEC to test the reliability and efficiency of the technology in real applications.

"This prototype is just the first step - there is a lot more to do," said Dr. Yuan. "But our results so far are promising and reflect a happy marriage between modern materials science and an old-fashioned energy technology, which provides a route for re-sparking the field of thermionic energy conversion."

Trump’s coal council to drill down on advanced technology – Washington Examiner

Posted: at 3:04 pm

President Trump's clean coal agenda could get some much-needed clarity as federal advisers take a hard look at advanced technologies to make coal plants more competitive and climate-friendly, as Trump's plan to repeal regulations will only go so far toward restoring the industry.

Some of the experts slated to lead the discussion at this year's spring meeting of the National Coal Council, a federal advisory committee, are skeptical about how much Trump can actually do over the next four years to help the coal industry beyond removing regulations.

Eliminating regulations is only a short-term remedy for what ails the coal industry. Removing Obama-era climate regulations would stop some of the planned coal plant retirements while allowing for the construction of newer, more efficient coal plants, which are considered a variant of clean coal technology.

Top consultants say the Trump agenda needs to be paired with a longer-term strategy that looks at more advanced technology such as carbon capture and storage, or CCS, which strips carbon pollution from coal plant emissions.

Amid Trump's promise to roll back climate change rules and withdraw from the Paris climate accord, much of the talk at the March 14-15 meeting will be on ways to make the coal industry more climate-friendly through the use of CCS. But even that isn't a sure fix, and it won't have job benefits for years to come, which is Trump's primary goal.

"I think everything that drives [Trump's] policy decisions is geared at the top level, first and foremost, to jobs," said Andy Roberts, research director for energy consultants Wood Mackenzie. "He wants to restore better economic health to the energy industry."

Roberts will deliver the keynote address, aptly named "Opportunities for Coal in the Trump Administration," at the coal council meeting, according to the official agenda.

When it comes to Trump's jobs priorities, Roberts doesn't see "clean coal" technologies that Trump continues to tout offering much in the way of putting miners back to work, at least not quickly.

"In the short-term, that means unburdening the industry from regulations to the extent [coal] competes on a level playing field," Roberts said. But clean coal technologies, primarily carbon capture and storage, "don't really impact employment in the industry in the short term and medium term at all."

Duke's Twitter page was inaccessible Monday afternoon during the suspension, the reason for which was not immediately clear.

03/06/17 1:48 PM

"It's not economic," Roberts added. "It's never going to be economic versus other forms of energy production." But it may still be necessary, he said, "depending on what the world decides it's going to do about topics like climate change."

That's why the primary thrust of the coal meeting will be focused on CCS and enhancing "the efficiency and emissions profile of our coal fleet," according to the agenda. However, the focus of the advisory panel in Trump's first year has not been determined, Janet Gellici, the National Coal Council's CEO, said before Rick Perry was confirmed as energy secretary Thursday. The coal council reports to the secretary.

The coal council under former President Barack Obama focused on legislative and policy recommendations for advancing CCS and even more advanced technologies that use the carbon to generate additional revenue stream for power plants.

One of the technologies that will be highlighted at this month's meeting will come from a company that has been collaborating with Exxon Mobil to commercialize a form of CCS technology for reducing emissions at natural gas power plants. The company sees fuel cells as a solution to the next big challenge for cutting carbon dioxide emissions, which is anticipated to be focused on natural gas power plants.

Currently, natural gas-fired plants are taking market share from coal, since they release 60 percent fewer emissions than coal plants. Gas plants, according to Exxon Mobil, are the reason the nation's emissions are at their lowest in 25 years.

Also from the Washington Examiner

Grassley said to Comey that Steele had at one point been paid by Democrats to dig up dirt on Trump.

03/06/17 1:45 PM

Nevertheless, any advancements in cutting carbon pollution further will stem from advancements that will come from developing CCS at coal plants, said officials with the company FuelCell Energy, which is collaborating with Exxon on CCS. Capturing carbon from natural gas is slightly different than capturing it from coal, but advancements on either would help the other fuel.

Officials with FuelCell Energy will be discussing its projects with the Energy Department, as well as the joint venture it has with Exxon. They say Trump's focus on manufacturing is good for clean coal, but also for cleaner forms of natural gas that they anticipate being needed further down the road.

"One aspect that we're certainly encouraged with is the focus on American manufacturing," said Kurt Goddard, head of investor relations for the company. "Because fuel cells represent American innovation, they represent American manufacturing."

Fuel cells had support in previous Republican administrations. Former president George W. Bush created the hydrogen fuel cell initiative to wean the nation off its "addiction to oil." But it's not clear if Trump might do something similar.

Fuel cells are a highly efficient means of producing electricity. Rather than burning a fuel, like a standard power plant does, they produce electricity through a chemical process using an electrolyte similar to a battery. But instead of charging it as a battery, the electrolyte is refilled. FuelCell Energy's device concentrates the carbon dioxide from a coal-fired power plant as part of its electricity-generation process. The process reduces carbon emissions and other pollutants.

It's also a form of clean energy that is completely made in America, Goddard said. "Our manufacturing facility is actually in Connecticut, whereas some other forms of clean power generation aren't necessarily made in the U.S.," he said, explaining why he believes Trump is supportive of CCS. It's a technology that is evolving, he said, with interest coming from Exxon, the Canadian oil sands and Europe.

Anthony Leo, the company's vice president for technology and applications, will discuss its fuel cell clean coal project at this month's meeting, in addition to the natural gas work he is doing with Exxon Mobil. The coal and gas projects are both being done at Southern Co.'s Barry Plant in Alabama.

The projects are in the engineering phase, with construction not expected to begin for about two years. Exxon CEO Darren Woods underscored the project in a blog post last month.

"Our role as the country's largest producer of natural gas which emits up to 60 percent less CO2 than coal for power generation has helped bring CO2 emissions in the United States to the lowest level since the 1990s," said Woods, who took over after predecessor Rex Tillerson was appointed secretary of state.

"But the world also will need breakthrough clean-energy technologies such as carbon capture and storage," he said, noting that the company is "investing heavily in CCS, including research in a novel technology that uses fuel cells that could make CCS more affordable and expand its use."

An Exxon official emphasized to the Washington Examiner that the company's piece of the project has received no funding or support from the government.

Roberts observed that the future of CCS could very well resemble what is being demonstrated between the fuel cell company and Exxon. He also said the "model" for clean coal could follow what is happening between SpaceX and NASA, where a private company "is driving a lot of our national space exploration activities, right now, at the direction of NASA but with cooperation."

Roberts sees demand for clean coal technology coming from Europe, where the continent's climate change policies require the technologies, even if Trump succeeds in exiting from the Paris climate agreement.

"Maybe if the U.S. steps back for a while, the driving factors happen in Europe," Roberts said.

Coal use is projected to grow globally, and there will be an increasing need for coal power plants to be made more efficient and with fewer emissions, said Benjamin Sporton, the head of the World Coal Association. He was in Washington last month to discuss advancements on coal technology with congressional staffers.

He was also in the U.S. as part of an International Energy Agency industry advisory team meeting with coal companies to get a sense of where they are on technology development, he told the Washington Examiner in an interview.

"For me it's a continuum," he said. "It's not saying let's leap to CCS today, because CCS is not a technology that is viable for widescale deployment today. It's about saying how we start on that pathway to get to somewhere further down the track."

Expanding federal incentives for carbon capture technologies was an idea supported by both parties last year. And a lobbying push by unlikely bedfellows, major coal companies and environmentalists, is gaining steam to move a similar bill in this Congress.

"When utilities, coal companies and environmental groups come together to support your bill, you know you're onto something that could work," Democratic Sen. Heidi Heitkamp of North Dakota said last year in introducing her bill to expand the coal incentives. Senate Majority Leader Mitch McConnell of Kentucky was a co-sponsor of the legislation.

Budget 2017: Chancellor to set aside 500million for technology, innovation and robotics to help Britain compete as … – The Sun

Posted: at 3:04 pm

Philip Hammond will put money into areas including electric cars and artificial intelligence to boost the growing sector

PHILIP Hammond is toset aside 500m for technology, innovation and robotics to help Britain compete after Brexit.

The Chancellor will use Wednesdays budget to give more money to fund research and development of electric vehicles, robotics and artificial intelligence.

PA:Press Association

He will use the cash to help British scientists and developers to compete with the rest of the world as the UK prepares to leave the European Union.

Ministers hope it will help to bring new jobs to the UK and attract foreign investment.

The money will include 270m for research and development for British business and universities.

And 90m will be to fund 1,000 PhD places in science, technology and engineering.

200m will go towards fellowships for researchers, and 50m for programmes to attract global talent to Britain.

The Chancellor is also set to announce more investment in broadband including a hub to test 5G technology. The Government could offer incentives for super-fast broadband too to help local businesses take up new networks and upgrades.

Mr Hammond is also set to use Wednesdays budget to announce he will put away money to help protect the economy from any turbulence as a result of Brexit.

He told Andrew Marr on Sunday he wanted to make sure Britain has enough gas in the tank as the UK prepared to start Brexit talks later this month.

He went on: My job as chancellor is making sure our economy is resilient as we embark on the journey well be taking over the next couple of years confident that we have enough gas in the tank to see us through.

Ghost Recon: Wildlands Review In Progress – GameSpot

Posted: at 3:03 pm

Subscribe for the latest gaming news

At its core, Ghost Recon: Wildlands is about information gathering. The drug dealers and terrorists you kill are just obstacles between your special ops unit and whatever clues you uncover. Hacking an enemy's computer or interrogating a wanted lieutenant can reveal half a dozen more leads and you're given the freedom to decide which lead to pursue next. Wildlands' openness and the flexibility of choice has, so far, been one of its strengths. Moreover, the first 10 hours of my playthrough amply provided a diverse sampling of what the greater game promises. It took little time to knock out the first batch of objectives, sample the local vehicles, and get reacquainted with the series' style of tactical gameplay.

Wildlands marks Ghost Recon's first foray into an open world, where its Bolivian setting is a playground of both destruction and distraction. You can infiltrate a stronghold with the best of stealthy intentions but you have to be prepared to wreck havoc the moment you're spotted. And the path to every main quest destination is littered with potential detours, whether it be an optional piece of intel or a medal that gives you a bonus skill point.

Ghost Recon's wild lands are expansive enough that using a helicopter is a practical method of transportation, given that the rocky region you start at isn't especially off-road friendly. The best part of taking a helicopter is jumping out of it and surprising enemies from above, provided you've unlocked the Parachute skill. Think of Wildlands as a less cartoony take on the Just Cause series with the all-business seriousness one expects from a Tom Clancy game.

Given the pre-launch videos and trailers' emphases on wanton mayhem and nondescript missions with friends, it was pleasing to watch a couple scene-setting cinematics shortly after firing up Wildlands. Even with the open world setting, I'm hopeful that it retains the series' emphasis on narrative and goal-driven missions. The ultimate goal is to take out El Sueo, the leader of the Santa Blanca drug cartel that essentially runs Bolivia. Your CIA contact, Karen Bowman also has a vindictive score to settle as one of her friends in the DEA was kidnapped and tortured to death by Santa Blanca. While revenge is a valid enough reason to upend a narco-state in the Clancyverse, I suspect that Karen might have other motives.

Forming squads has been one of Wildlands' more intriguing features during these initial hours. In keeping with Ghost Recon's history of team foursomes, having a full squad made up of your friends is the ideal experience. So far, a team of four humans with at least a modicum of experience in tactical shooters is a powerhouse in Wildlands even though enemy headcounts adjust to scale with the size of your team. Players who already have a squad in mind might want to consider starting off the game at the highest difficulty. However, playing solo with a squad of three AI companions offers its own unique benefits. When coordinating a synchronized kill of three targets, the AI is reasonably efficient in moving to reach line of sight within seconds. And they're more durable than your friends when taking fire, which is immensely helpful if they're out in the open healing you. What is puzzling is that you can't have a mixed team of humans and AI. If you and a friend are playing a private session, you can't round off your team with two AI operatives. What's all the more amusing is that you can still hear the story-related banter between all four squadmates.

There's comfort in falling into a tactical routine with your buddies as you reach the perimeter of every enemy outpost. This infiltration cycle begins when you use your tiny drone to survey the stronghold and mark all visible enemies. The ability to track marked enemies through multiple walls feels like cheating, though it hasn't diminished the appeal of the many other Tom Clancy games that use this feature. The openness of Wildlands makes this feature all the more essential and helps your team decide on the best strategy. It remains to be seen whether Wildlands retains the same gadget appeal of Ghost Recon: Future Soldier later on in the game, though perhaps a drone is all the advanced tech you need in Bolivia.

In the 10 hours I've spent on the road to liberate Bolivia of El Sueo's rule, I've unlocked 20-percent of the map. As I've slowly made my way through the hit list of underlings, I've been curious about the risks of sticking to the critical path, and whether there's such as thing as being underleveled in Wildlands. That said, it's been easy to take brief detours to earn extra experience and skills, thanks to the added efficiency of my teammates, AI-controlled or otherwise. Whatever path my journey takes, I know it will involve more diversions to earn extra abilities, the takedowns of the boss' lieutenants, and the elimination of El Sueo himself, which I estimate will take an additional 30 to 40 hours. Stay tuned for our full review in the coming days.

Pick-and-Pop: Parsons’ ‘progress,’ weekend notes, more – The Commercial Appeal

Posted: at 3:03 pm

Grizzlies forward Chandler Parsons was hard on himself after playing a back-to-back for the first time this season. Ronald Tillery/The Commercial Appeal

Some post-weekend Grizzlies thoughts:

Parsons Progress: Chandler Parsons played his first back-to-back of the season, and his second most individual-game minutes of the season against Dallas, with 9 points on 4-16 shooting in 44 minutes over both games and the same physical limitations weve seen all season.

Was simply playing the back-to-back a sign of progress, as it was touted, or a sign of the team trying to force some progress as the clock ticks toward the playoffs?

The storm and stress surrounding the Parsons question is getting a little tiresome. Its not about his now-dormant social media, his off-court adventures, how hard he works, how early he shows up or how late he stays at practice, or whether shutting down for the season would be theact of a coward, to choose his own word. This is not an issue of morality or machismo. Its a simple two-part question: 1. Is Parsons healthy enough to be on the court? The answer to that is apparently yes. 2. Is he healthy enough to help the team when hes there? So, far the answer to that is no, with no particular reason to believe that will change in the next few weeks. And yet context complicates.

One thing that props up an apparently indefinite patience with Parsons lack of progress is the battery of alternatives. Last week in this space, I worked through some lineup alternatives, which on the wing would mean James Ennis, Vince Carter, or Troy Daniels. None of them, at this stage, should be a starter on aplayoff team.

Theres a two-part opportunity cost to continuing to play Parsons despite his ineffectiveness: 1. That the team has consistently been worse with Parsons on the floor than with the players who would take his minutes, and the games now matter if the team cares about maximizing its playoff seeding. 2. If Parsons is still this player come mid-April, its hard to believe hell maintain this role in the playoffs, so the team is just delaying the process of settling on the lineup and rotation it will use in the postseason and getting that rotation some reps.

If were making this about the team, and not about Parsons, which is how the discussion should be centered, then theres this counter-argument in favor ofthe status quo: The alternatives arent much better than even the current Parsons. Carter and Daniels have each shot below 36 percent over their past 10 games, in a rotation role, and each has definite limitations at full health. Daniels isnt just squeezed by Parsons, but by Toney Douglas taking over a big chunk of back-up scoring guard minutes, a development that is lessabout Douglas individual production than abouthow his ball-handling has helped maximize Mike Conleys impact. Ennis has mostly been out of the rotation lately, but his own limitations are exposed when he gets heavy minutes.

The math for Parsons at this point: That the slim chance of him yet improving with playing time presents a greater path to post-season upside than the minor improvements to be found in benching him. No one with the Grizzlies is going to put it that plainly, but thats the calculation, and it could well be the right one.

A Two-Man Game Wed Love to See: In the playground of our dreams if not on an NBA court.

Other Weekend Notes: Both weekend losses are easy to rationalize individually: This Dallas Mavericks team, with Nerlens Noel, Seth Curry and Yogi Ferrell all in the lineup, is far better than the teams full-season record indicates, and even that record is good enough to be in the playoff hunt. A four-point loss on the road to that team is no disgrace. Neither is running out of gas on the second night of a road back-to-back against a relentless Rockets team.

The problem with that, as noted after last weekends road split: Acceptable isnt good enough if the Grizzlies still harbor hopes of moving up in the Western Conference playoff race. Record-wise, the NBAs three best teams are all in the West, and getting into the 4-5 game and avoiding those teams should be the goal. The Grizzlies cant play at the level theyve shown since the All-Star break and get there.

While the attention has been on Parsons, the biggest concern at the moment might be Marc Gasol. The Grizzlies can hope for secondary help, but this season has shown they cant depend on it. They need the Gasol-Mike Conley-Zach Randolph trio to carry them.

Gasol struggled defensively with younger, quicker centers in Dallas Noel and Houstons Clint Capella over the weekend and has been erratic on the offensive end for the past month. Hes topped 23 points in a game 20 times this season, but only once in the past month, and that in a home routagainst Phoenix, one of the NBAs very worst defenses.

Over the weekend, Gasol played 36 minutes in each half of a back-to-back. Setting aside his recovery from foot surgery, hes a 32-year-old center. Hes 17th in the NBA so far this season in total minutes. The only older players in the Top 20(and both just barely) are Carmelo Anthony and Lebron James. The only centers who have played more are Karl-Anthony Towns and Rudy Gobert, ages 21 and 24, respectively. Gasol scoffs at such things, but is it unreasonable to wonder if hes worn down some?

Gasols three-point shooting percentages per month:

Regression to the mean? Slump? Random variance? Fatigue? All answers are possible. But for the Grizzlies to be good down the stretch and competitive in the playoffs, a return of All-NBA caliber Gasol is mandatory.

Elsewhere in the Playoff Race: The Grizzlies have been helped by Oklahoma Citys inability to win on the road. The Thunder went 0-3 on a long-weekend road trip and only the Indiana Pacers have been worse on the road among teams with winning records overall. This has helped the Grizzlies maintain a full game lead over the Thunder despite their own struggles, but the Thunder will play six of their next eight back at home.

The Clippers have been playing .500 ball for a while now, and the return of Chris Paul hasnt (yet) changed that. They have a tough one at home tonight against Boston before coming into Memphis for a big game on Thursday, on the second half of a road back-to-back.

The Jazz were my preseason pick to jump from the lottery to the Wests Top 4 and they seem to be strengthening their grip, building a three-game lead over the Grizzlies. But their schedule takes a much tougher turn after tonights home game against New Orleans. Standings as of today:

Game Minus Presentation?: So this happened over the weekend, and this reaction from Friend of Pick-and-Pop Tim Bontemps was common among full-time NBA media:

This would be a fun experiment for one game (and it happened in Memphis by accident for half a game last season), but I cant fully get behind the general idea. As a music nerd, I like the snippets Grizzlies DJs expertly sprinkle into game action (favorites: David Bowie, Tribe Called Quest, Pete Rock & C.L. Smooth). I like Mike Conleys Dad Jokes and Zach Randolphs Deep Thoughts. I like Bongo Lady and the Mike Conley Road Runner beep-beep, the ceremonial fourth quarter Whoomp! There It Is! and the occasional well-earned deployment of the Gap Band. This isnt just a Serious Sporting Event. Its a community party. There are elements of game presentation I dont like or, much more often, just dont care about, and I find it easy to tune those things out. No harm done.

All of that said, there is one aspect of game presentation Id march on the frontlines against: Can we please lower the volume on pre-game, in-arena music? I cant hear myself think, much less have a human conversation. I dont need to be engaged during the pregame shoot-around. I can fend for myself.

100 (Or So) Word Preview: The Grizzlies dont just need to start stringing together wins, they need to start playing better. But theres no upside tonight as the NBAs worst team, the Brooklyn Nets, make their lone FedExForum appearance of the season. The Grizzlies need to notch this win and to do so without strain or drama. A big win, as against Phoenix last week, wont really mean much. It just has to happen. If youre desperate for intrigue: Which center, Marc Gasol or Brooklyns Brook Lopez, makes more threes? If you want to worry: Best bet for being tonights Sam Dekker or Doug McDermott, the secondary wing scorer who has a career night? Keep an eye on Sean Kilpatrick.

Maryland’s Will Likely, unable to run at combine, pleased with progress of injured knee – Baltimore Sun

Posted: at 3:03 pm

Former Maryland cornerback Will Likely looks around at some of the other participants at the NFL scouting combine and sees guys he played against in college or faced while growing up in Florida.

He admits it stings that he won't be competing with them Monday at Lucas Oil Stadium when the defensive backs get put through their on-field workouts, and that he can't show his speed and athleticism by running the 40-yard dash or doing the other testing.

However, given how far he already has come since his productive Terrapins career ended when he tore the ACL in his right knee while returning a punt Oct.15 against Minnesota, Likely isn't having too much trouble remaining patient.

"You have to run your own race, take it one day at a time and eventually you're going to be able to show what you can do," Likely said Sunday. "I'm way ahead of schedule. Just for me to get invited and just to be here, that's a blessing in itself. I don't take anything for granted."

Likely, the only Terp invited to the combine, will only do the bench press Monday as he continues his recovery from knee surgery. He expects to graduate to position drills on March 29 at Maryland's pro day. However, the past couple days have given Likely the opportunity to meet with teams and show them how much physical progress he has already made.

"I'm going to be back healthy, and whoever picks me will know what they're getting out of me," Likely said. " The coaches have been liking what they've heard and they like my film. That speaks for itself, but just getting to know those guys, just building a relationship with them, it's been pretty good."

Likely played 43 games at Maryland over parts of four seasons, registering 229 tackles, two sacks, seven interceptions and five forced fumbles. He established himself as a home-run threat with the ball in his hands, and one of the most dangerous return men in the country. He returned two interceptions, two kickoffs and four punts for touchdowns in his career and his 2,233 career kickoff return yards are the second most in Terps history.

At 5-foot-8, Likely understands he'll face skepticism in a league that covets big and long cornerbacks. However, he believes he has proven that he's a "competitor and a true playmaker." He also thinks his special teams prowess should help his draft status.

Likely said he has blocked out any talk about where he might be drafted, preferring to keep his focus on rehabbing his knee. He has been working in Phoenix with Brett Fischer, who runs a physical therapy and performance facility. About five months out from surgery, Likely is already running and doing other defensive back drills.

With his pro day 3 weeks away and the draft about eight weeks away, Likely is thrilled that he's in the position he's in.

"I'm a firm believer that everything happens for a reason," he said. "It's just a blessing that it happened at this point. Now, I know what it's like [to deal] with adversity. Once it's time to get ready to play on Sunday, I'll be past that and have a strong mindset. It will be full speed ahead."

Following Young's lead: Temple cornerback Nate Hairston hasn't needed to look very far to get motivation or advice as he goes through the scouting combine. Last year, his former teammate and close friend, Tavon Young, represented the Owls at the combine before he was drafted by the Ravens in the fourth round.

"Any time I needed something or had a question, that's like my best friend, that's like a brother to me," Hairston said Sunday. "I'm hitting him up [like] 'Hey, what about this or what about that?' And he'd always shoot me some advice all the time. That's like family to me. Him going through this process last year was a big help to me this year."

Hairston is a Frederick native who played high school football at Thomas Johnson High. Temple gave him his only scholarship offer and he transitioned from a wide receiver to a defensive back in time for his redshirt junior season. Now, like Young, he's on the cusp of making the NFL.

"Any time you see someone that you're that close to have that success, it's like, 'I can do it, too. I want to do it, too,'" Hairston said. "It definitely pushed us and made us chase the same dream."

End zone: Michigan pass rusher Taco Charlton said he would welcome going from one Harbaugh brother to the other. "I loved playing for Jim Harbaugh. I would love to play for John Harbaugh, just because I know how the other Coach Harbaugh was for us and he has that same passion for football." Texas A&M pass rusher Myles Garrett, the presumed first overall pick to the Cleveland Browns, ran a 4.64 40-yard dash Saturday. That was the fastest time among defensive linemen in the first on-field testing session. The majority of Ravens officials are expected to return to Baltimore late Monday following the conclusion of the defensive backs' workouts. The two-day free agent negotiation window, which precedes the market officially opening Thursday afternoon, begins Tuesday.

Tech analysis: How Renault made big progress with its 2017 car – Motorsport.com, Edition: Global

The RS17, fourth-quickest on pure laptimes among the F1 contingent in Barcelona, looks a major step change compared to the RS16. That car was compromised by the late takeover of the team but more weight has clearly been thrown behind this year's challenger.

The bargeboards and airflow conditioners are an extremely complex area of the car given the change in regulations for 2017. Renaults boomerang-shaped airflow conditioner is testament to this and features three slots in its lower surface in order to improve efficiency, while the bargeboard is shaped to maximize the upturned leading floor edge.

Details presented on the launch car looked somewhat different come Barcelona, with the curved cockpit fin (white arrow) now featuring a curved tip which will shed a very specific type of vortex and the planned twin vortex generator alongside (red arrow) changed for just a longer, singular appendage.

The team also introduced a blown axle solution during testing which will assist the front wing in dealing with the wake generated by the front tyre.

The legality of Renaults rear wing support pillar was questioned by several teams following the car's unveiling, as it connected directly to the DRS actuator pod rather than connecting with the mainplane (arrowed). Of course, Renault wanted to use this solution as it improves the performance of the rear wing, given the mainplane is less disturbed.

It's understood that the FIA has since clarified their position, advising that the design must be tweaked ahead of the Australian Grand Prix in order that the pillar intersect with the mainplane.

Toward the end of the first test, the team also trialled a tall upper flap with a large central V cut, which is likely for simulation purposes - its height will undoubtedly be called into question if the team was to try to run it during a race weekend, as the flap clearly exceeds the 800mm height for bodywork behind the rear wheel centerline mentioned in article 3.6.2 of the technical regulations.

Although that's not to say that Renault hasn't found a contradictory statement in the minutia of details that connect one article in the regulations with another.

Singularitarianism | Transhumanism Wiki | Fandom powered …

Posted: at 3:03 pm

Singularitarianism is a moral philosophy based upon the belief that a technological singularity the technological creation of smarter-than-human intelligence is possible, and advocating deliberate action to bring it into effect and ensure its safety. While many futurists and transhumanists speculate on the possibility and nature of this technological development (often referred to as the Singularity), Singularitarians believe it is not only possible, but desirable if, and only if, guided safely. Accordingly, they might sometimes "dedicate their lives" to acting in ways they believe will contribute to its safe implementation.

The term "singularitarian" was originally defined by Extropian Mark Plus in 1991 to mean "one who believes the concept of a Singularity". This term has since been redefined to mean "Singularity activist" or "friend of the Singularity"; that is, one who acts so as to bring about the Singularity.[1]

Ray Kurzweil, the author of the book The Singularity is Near, defines a Singularitarian as someone "who understands the Singularity and who has reflected on its implications for his or her own life".[2]

In his 2000 essay, "Singularitarian Principles", Eliezer Yudkowsky writes that there are four qualities that define a Singularitarian:[3]

In July 2000 Eliezer Yudkowsky, Brian Atkins and Sabine Atkins founded the Singularity Institute for Artificial Intelligence to work towards the creation of self-improving Friendly AI. The Singularity Institute's writings argue for the idea that an AI with the ability to improve upon its own design (Seed AI) would rapidly lead to superintelligence. Singularitarians believe that reaching the Singularity swiftly and safely is the best possible way to minimize net existential risk.

Many believe a technological singularity is possible without adopting Singularitarianism as a moral philosophy. Although the exact numbers are hard to quantify, Singularitarianism is presently a small movement. Other prominent Singularitarians include Ray Kurzweil and Nick Bostrom.

Often ridiculing the Singularity as "the Rapture for nerds", many critics have dismissed singularitarianism as a pseudoreligion of fringe science.[4] However, some green anarchist militants have taken singularitarian rhetoric seriously enough to have called for violent direct action to stop the Singularity.[5]

Interview with Deo Ssekitooleko Representative of Center for Inquiry International Uganda – Conatus News

Interview with Deo Ssekitooleko Representative of Center for Inquiry International Uganda

In brief, what is your family story?

I was born in a poor African family. I firstsaw my biological father when I was ten years old. I am the heir of my late father, Fulgensio Ssekitooleko. He was a very committed catholic, very social, and a committed humanitarian. I grew up with my mother Noelina Nalwada which was typically asingle-parent household (but atother times I had step-fathers). I am the only child. My fathers children, apart from one, died after getting infected with HIV/AIDS in the 1980s and 1990s. My mother is an atheist, agnostic or skeptic. When I tried to enter a catholic seminary, she abused me and challenged me whether I hadever seen somebody who has ever seen God or returned from death.

However, one of my last stepfathers who was both a devout catholic and a believer in African traditional religion influenced me to be a very religious person (Catholic) in my early youth. My mother knew how to fight for my (and her) rights, so I never understood issues concerning human rights violations during my youth except when seeing teachersapply corporal punishment to my fellow students. As I was growing up, I was not aware of the massive human rights abuse by the governments of the day, but, once in a while, I could hear whispers about somebody who has disappeared or killed by the government. Those were regimes of president Iddi Amin Dada, and the second regime of Apollo Milton Obote as he was fighting guerrillas lead by Yoweri Museveni the current president of Uganda

I am married to Elizabeth, and we have been togetherfor 17 years. We have four children: Sylvia (16 years), Diana (12), Julius (11), and Nicholas (3).

Are there any others things about your personal story you would like to share? I grew up striving to succeed in education so that I could escape poverty, ignorance, and unfairness in society. My mothers relatives were always exploited by witchdoctors who claimed to have healing-powers and thus could curediseases including HIV/AIDS. My uncles and aunts gave away their land to witchdoctors in order to get cured from HIV/AIDS, but they later died leaving no property to their offsprings.

In the years to come, the Pentecostal movements emergedpromising prosperity on earth, good health and many other opportunities. The two groups, i.e. the traditional religions and the Pentecostals, were undermining the struggle against HIV/AIDS, exploiting poor people. Yet, nobody could talk about them or challenge them.

This was a traumatising experience. I never knew whether this was a human rights issue or mere belief, or ignorance. As the 1948 Universal Declaration of Human Rights defends the right to belief, all governments have gone on to include that article in their constitutions.

This means that ignorant people can be exploited in the name of belief as it is their human right to be exploited as long as they believe. This has been one of my most traumatising struggles in life. I have lost so manyrelatives out of their ignorance of science concerninghealth issues. Yet, governments cannot do anything about this because the politicians are also superstitious and the laws protect the charlatans.

In Uganda, almost 80 per cent of FM radio stations spend most of their time promoting the work of faith healers and witchdoctors. Rationalists do not have resources to own a radio station or to buy time on radio and television.

In my struggleto promote rationalism, I founded the Uganda Humanist Association. I became the East African Representative of the International Humanist and Ethical Union (2007-2012). Now, I am the Ugandan Representative of the Center for Inquiry International.

As advocacy campaigns are difficult, we now engage with local communities to talk about science and superstition in health and community development. Our work is now to invite whoever happens to be involved to discuss these issues openly and inform communities of the dangers of superstition in health and community development.

As of now, I have personally suspended armchair conference-hall humanism. I am in the trenches of community practical humanism. Whatever little I do, I feel proud that at least I am part of the struggle to rationaliseAfrican communities.

What are your religious/irreligious, ethical and political beliefs? I grew up as a staunch Catholic, and then at university I became a radical secular humanist. Now, having interacted with various so-called humanists and observed their limitations (especially in building harmony, inclusive communities, practical approaches to society problems, and a general lack of openness)I have reviewed my humanism.

I am now a free thinking, liberal, practical humanist. I do not mind other peoples beliefs on the condition thatthey do not infringe on the rights, happiness, and welfare of other human beings. I can work with Catholics on a health project, but I tell them point blank that the use of condoms should not be underminedand that family planning is essential in our families.

I tell Pentecostals that by preaching miracles such as faith-healing they are committing homicide. However, I enjoy my intellectual philosophical humanism as we debate Darwinism, the Big Bang theory, the environment, and the future of humanity among others. Politically, I am a social welfare democrat. Democracy should not be only about elections, but on how society shares opportunities and resources and how it promotes harmony.

I do not support the winner takes it all type of democracy. I prefer proportional representation in government as a form of democracy,as is the case in many countries which suffered the madness of the second world war.

How did you become an activist and a sceptic? When I enrolled inhigh school, I was still a very confused young man. I had experienced a lot in my childhood. My Biology teacher, the late Mathias Katende, made an explosion in my brain and changed my ideological worldview. He introduced evolutionary biology to us.

The more he taught, the more we became confused. All along, I had prepared myself to go to heaven and meetMary, the mother of Jesus, and escape worldly problems. However, by the time I entered University to study Botany, Zoology, and Psychology, I had become completely healed from this ideological and philosophical trauma.

At University, we got more lessons on evolution, but the lecturers were not as committed to evolution as my high school teacher. In fact, most students never took evolution seriously. They just wrote their examinations and moved on with life.

At university, by luck, a friend gave me a book on discovering religions. I read about most religions, worldviews, and philosophies. I found Humanism to be more related to my new worldview. I wrote to the British Humanist Association and got a positive response from Matt Cherry who encouraged me to form a humanist organisation. That was the birth of the Uganda Humanist Association.

He connected me to the center for Inquiry International through Norm Allen who was the Director of African Americans for Humanism (AAH). The Free Inquiry Magazines that Norm sent us opened our eyes wider on how humanity sees itself. Later, we were to work with the International Humanist and Ethical Union (IHEU) on many secular projects.

Do you consider yourself a progressive?

I am very progressive. I have always been evolving in my ideological, philosophical, cultural, and political views. I used to be a staunch believer in American democracy, but now I am more rotated towards European Social Parliamentary Democracy. I used to hate Chinas politics, but now I see it relevant in order to maintain orderliness and social welfare to a country (that has over one billion people) under one authority. I am a progressive because I am ever open to new challenges, new ideas, and new world views for the good of humanity and the environment at large.

Does progressivism logically imply other beliefs, or tend to or even not all?

I dont look at progressivism as a confined ideology or philosophy. If so, then I need more education about it. In my view, progressivism should be open to all aspects of human life including but not limited to culture, beliefs, politics, philosophy, and views about the environment among others.

How did you come to adopt socially progressive worldview?

As I explained earlier, it is a combination of my childhood experience, my culture, my environment, and possibly my inherited biological genes. I am lucky to have been introduced to evolutionary theory by my high school biology teacher and through reading various related literature including Richard Dawkins The Blind Watchmaker. The works of Philosophers such as Thomas Paines The Age of Reason taught me critical reasoning skills. Studying the American revolution was equally important in my political thought development. I was humbled by the sacrifices of Nelson Mandela and his colleagues to liberate South Africa from apartheid. Julius Nyereres trials with community socialism in order to liberate Tanzanians from poverty and to unite them into one nation was a positive human commitment. I can not forget reading the life of Bill Clinton in his voluminous autobiography. It is a story of moving from no where to the top of the mountains of his country.

Demonstrators oppose free speech – The Missoulian

Posted: at 2:57 pm

Once again it appears we are living in an alternate universe. In Montana and all over the United States of America, the elitist progressive liberal globalist socialist anarchists (EPLGSA) who claim to be advocates for free speech are demonstrating just exactly the opposite and looking really, really stupid doing it.

Has our civilized American society been broken down by the EPLGSA to the point where only the loudest, noisiest side can be heard? When our elected officials offer the opportunity for an exchange of information between themselves and the electorate, how does it serve anyone by having the EPLGSA totally disrupt such gatherings? How is it that the EPLGSA could be so arrogant that they think their free speech rights trump everyone elses free speech rights? But, arrogance seems to be a natural trait of the EPLGSA.

The time has come for accountability. Is it time for law enforcement agencies to put order back into law and order? Why should taxpayers be footing the bill for these goofball demonstrators? If these people wish to tear things up, let them pay for the damage.

For my liberal progressive friends; does this intolerant behavior make you proud? How is this good for America?
