RCA Airnergy Charges Gadgets with Nothing But Wifi Signals [Chargers]

Forget PowerMats and wireless charging and the like, because the Airnergy wi-fi signal harvester is my new front runner for the future of gadget charging.

It's not exactly new tech, as ohGizmo notes, but it's the first application that's of any real use to consumers. Put simply, Airnergy takes the energy created by wi-fi signals and stores it in a rechargeable battery. At CES, the device's battery, which I believe was precharged with Wi-Fi power, was able to charge a BlackBerry from 30% power to full power in about 90 minutes.

Pretty handy, and supposedly available this summer for $40. Not too shabby, and very appealing considering how ubiquitous wi-fi hotspots are these days. Very simple, somewhat cheap and incredibly useful if it works are advertised—by far one of the coolest things I've seen come out of CES this year. [OhGizmo]



How to Convert a 1940 6 volt Ford to 12 volt

I should also ask is there another solotion to our problem.

The car is a 1940 Ford Coupe with 6 volt electrics in it. The car belongs to an uncle of mine who has just had the motor rebuilt and now it drains the battery just trying to get it started. Anyway he is old and figures the best th

Impressive RCX-4 Helicopter Will Share the Sad Same Fate as Dak [Knockoffs]

For many X-Wings in the Star Wars universe, the end came as a spectacular explosion on the field of battle. Not so much for this RCX-4 helicopter. For it, the end will no doubt arrive as a boring ol' lawsuit.

First spied at CES, hovering in the air and openly thumbing its nose at George Lucas and Lucasfilm, the RCX-4 is a four screw beast of an RC helicopter that bears more than just a passing resemblance to the workhorse of the Rebellion. And like Dak, Luke's enthusiastic but doomed gunner in The Empire Strikes Back, it too feels as though it could take on the whole Empire by itself, if not for that pesky IP issue that will surely bring it down very, very soon.

So its days are numberd, but even so this knockoff sounds decidedly un-knockoff in the quality department. Developer Digitronics promises easy flight thanks to an on board gyro and simple controls. The aluminum case is beefy. The asking price is steep. The chopper even has the ability to hover safely in place all by its lonesome, should you have to put the controller down to take receipt of a subpoena or something. [ars technica]



Did Your Company Get Kicked Out of CES (and Not Get to Show Us Your Cool Stuff)? [Ces 2010]

DailyTech reports that a number of companies with tiny budgets who resorted to the survival tactic of showing their new gear at hotel suites around Vegas during CES were kicked out of hotel rooms they paid for by CES's organizers.

One company was reportedly ordered to pay a $10,000 exhibition fee to the CEA, the organization behind CES, in order to continue showing their products in their hotel suite.

If you're one of the companies who got booted, we'd like you to pitch us your new stuff, so we know we didn't miss you because of the CEA. [DailyTech]



HV Motor Testing – 6.6kV

Motor is 3300KW @ 6.6kV

I know this does not make sense but :

Motor does not run up but reported to behave as though single or 2 phasing

Switchboard voltage drops by around 500V, even when motor was started uncoupled from its pump

Motor PI, IR & winding balance tests all ok

A Charged Battery Is But 130 Conceptual Twirls Away [Batteries]

We've seen batteries charged by outlets and by cranks, but this concept from designers Song Teaho and Hyejin Lee is the first that charges with a twirl.

However, like all things tagged concept, this battery doesn't *technically* exist yet.

Still, Teaho and Lee both hypothesize that this battery, should it become the real deal, would require about 130 twirls for two-minutes talk time.

From what I've seen of crank-charged batteries, that seems relatively plausible (and tiring). Get to work, fellas. [design(dot)fr via Engadget]



Netflix Voyeur [NetFlix]

The New York Times takes an interactive look at what Netflix users are watching in a dozen U.S. cities, including my backyard, Boston. My neighbors are watching what now?

Oh, just Mad Men, it seems, with a sizable pocket in Cambridge. We're so liberal.

And why the heck was Eagle Eye so popular on the North Shore last year? Anyone? [New York Times via Slashdot]



Smart Bowling Ball Searches for the Perfect Technique [Bowling]

The few times I go bowling each year are more about pitchers of cheap beer than they are satiating some desire for the perfect game, but nevertheless I'm intrigued by this "smart ball" from the Royal Melbourne Institute of Technology.

Developed by sports scientist Franz Fuss, the smart bowling ball contains aluminum tubes in the finger holes that track the force a bowler applies to each roll. Fuss had ten bowlers of different skill levels bowl various shots down the lane, measured the force, and used it to try and find the perfect shot.

The simple system found that the better bowlers were consistent (surprise!), in that they always pinched the ball with "much greater force prior to release." This allowed for a much faster delivery than the newbs, and of course higher scores. [New Scientist]



STS-130 Launch Delay?

STS-130 Shuttle flight facing delay due to Payload technical glitch, Universe Today

"The launch of Shuttle Endeavour on the STS 130 flight now faces a potential delay due to technical problems with the external ammonia connecting lines which are designed to provide critical cooling capability to the new Tranquility module. Tranquility is a pressurized module being brought aloft as payload in the cargo bay of Endeavour on the STS 130 mission. Launch of Endeavour is currently set for 4:39 AM on Feb. 7."

Carbon steel

We have Carbon steel piping for Boiler feed water having pressure of 100 bar and temp of 200 Degree C.

Amalgamation [Clocks]

The Westminster Chiming Grandfather clock is an obelisk of discarded toys. At 2.2 meters tall, it's also a monstrous, functioning timepiece that now resides in, where else, Dubai.

But how was it created? Well, just a little Buzz Lightyear here, Hulk action figure there, and then a coat of high gloss polyurethane white paint to seal everyone in.

There are more out there, says designer Ryan Mc Elhinney, with the toys used symbolizing the client's childhood memories. This leads me to believe some clocks are far scarier than others. [Dezeen]



Desalination Process

I need to make a desalination system which should be small in size, should consume less energy and time. It should be able to desalinate 500mL of 3% by weight of sodium chloride solution at a time.

I need suggestions ,please someone help me out.

Best regards

Vertical Washing Machine Drain

Is there a cheap and dirty way to prevent back-flow from an improperly plumbed washing machine drain? It goes up about 8 feet to a DW line with a check valve in between. The check valve gets clogged up from washer waste (seems obvious) and fails to prevent contaminated waste drain from flowing do

Microvision Pico-Projector Game Controller Hitting Walls Later This Year [Video Games]

The Microvision pico-projector video game gun controller we profiled last month might actually see the light of day—and soon. Who's ready for some murky, awkward angle FPS fun?

I mean, I kid Microvision about the fact that you'd need a cylindrical room with nothing on the walls and no light to use this controller properly, really, but nevertheless—my angst aside—there seems to be enough demand in place that their CEO is going to market this thing sooner rather than later.

CEO Alexander Tokman said manufacturer samples are slated to be sent out later this year, with cellphone, video game and other markets creating real, live products sometime in 2011. Because random, screaming kids playing Gears of War 2 on the side of the subway during the morning rush would be totally cool with me... [Projector Info]
