Simple..
Can any one explain:
In case of cells.. We normaly says that "charge went out".
Does it refers to the voltage decress or current decrease.???
For ex: A 20v battery - Does it means that this battery can provide 20 voltage to a specified time?

This might be rather old, but i was just wondering how the calculus was devised by Sir Isaac Newton and Gottfried Leibniz. I have read their history, but was it true and can it be proven that how they came up with it ,individually, is true? Furthermore, how far can the history of integral and differ
Solar Power Bill Introduced by Sanders
A year ago the Obama administration enacted the $787 billion American Recovery and Reinvestment Act (ARRA). Last week, President Obama linked economic recovery to investments in clean energy and green job creation in his State of the Union address. Meanwhile, unemployment is still very high (9.7% last month officially) and 20,000 jobs were also lost last month. Where is the green jobs revolution? We need it now more than ever. The U.S. should be churning out solar panels and creating hundreds of jobs with their installation on American homes and businesses. This is exactly what a few smart Congressmen want.
Congress has waited so long to pass a meaningful climate change and green jobs bill that China is way ahead of the U.S. in building solar panels and wind turbines. The stimulus was never meant to be the only spending on green energy that we did in the near future. It was only the start. This is responsible spending because it will create jobs.
More than $200 billion of the stimulus package was earmarked for projects that would either directly or indirectly create green jobs. (The second reporting by ARRA recipients was made public on recovery.gov last Saturday.)
Last Thursday, Sen. Bernie Sanders (I-Vt.) introduced a bill aimed at getting 10 million new solar rooftop systems and 200,000 new solar hot water heating systems installed in the U.S. in the next 10 years. This is exactly what the U.S. needs right now! This is from Grist.
Titled the “10 Million Solar Roofs & 10 Million Gallons of Solar Hot Water Act” (PDF), it would provide rebates that cover up to half the cost of new systems, along the lines of incentive programs in California and New Jersey (not coincidentally, Nos. 1 and 2 in installed solar in the U.S.). It also includes measures to insure that those who receive assistance get information on how to make their buildings more energy efficient.
Sanders currently has nine co-sponsors: Environment and Public Works Committee Chair Barbara Boxer (D-Calif.) and Sens. Patrick Leahy (D-Vt.), Frank Lautenberg (D-N.J.), Robert Menendez (D-N.J.), Sheldon Whitehouse (D-R.I.), Ben Cardin (D-Md.), Jeff Merkley (D-Ore.), Kirsten Gillibrand (D-N.Y.), and Arlen Specter (D-Pa.).
The bill would accelerate what is already a fairly rapid pace of growth for distributed solar power. Distributed energy has a number of advantages over its central-plant competitors (both clean and dirty): it’s faster to build, avoids the need for expensive transmission lines, can use already developed land, and enhances community resilience and self-reliance. It’s also labor-intensive, creating more jobs per dollar of investment than its competitors—a feature that may make it more attractive during a recession, when Democrats are turning their attention to unemployment. In part he said,
Sanders: The fact is that every state in this country can produce at least 10 percent of its electricity from solar. [Sanders’ press release cites ISLR’s report on Energy Self-Reliant States.] In Vermont, we’re moving on solar. New Jersey is one of the leading producers [...]
Former NASA Astronauts On Commercial Space
We are Ready for Commercial Human Spaceflight, Leroy Chiao
"Many of my colleagues and peers have written articles and pieces, deriding the idea of commercial LEO access. Indeed, the track record of the self-described "New Space" companies has thus far, been marked generally with failure and arrogance. Not all, but many of these folks, before they run their companies into the ground, seem to spend the bulk of their time attending self-serving, self-aggrandizing conferences where openly slinging mud at NASA is sport. This is hardly constructive, and it brings discredit to others who have serious aspirations for the future of commercial spaceflight."
Launching NASA on a Path to Nowhere: Analysis, Tom Jones
"The new budget, announced Monday, seems merely an attempt to disguise the demise of U.S. leadership in space. The president does away with Constellation, its Orion spacecraft, and its Ares I and Ares V boosters. The abrupt cancellation means the U.S. no longer wishes to send its explorers to the frontiers of knowledge and spacefaring skill. We are deliberately choosing to have no better space capability than do Russia, China, or India."
Boosters Flare in Space Debate, MSNBC
"Another former shuttle astronaut, Ken Bowersox, is more bullish on the commercial prospects - perhaps in part because he's now an executive at one of those companies, California-based SpaceX. Today Discovery News quoted him as saying that space contractors "should be able to come up with new and innovative ways" to fill NASA's needs for resupplying the International Space Station."

From Mushrooms to Mansions: Organic Building Materials [Fungus]
Philip Ross works with a mushroom farm called Far West Fungi. And on it they're growing your future house. Or at least the nontoxic, fireproof, mold- and water-resistant building blocks for it.
There are dozens of mushroom-filled shipping containers on this farm, but what Ross is after are the "fungi's thin, white rootlike fibers" also known as mycelium. He's after these fibers because they make great building blocks:
Mycelium doesn't taste very good, but once it's dried, it has some remarkable properties. It's nontoxic, fireproof and mold- and water-resistant, and it traps more heat than fiberglass insulation. It's also stronger, pound for pound, than concrete.
If you doubt how strong the material is, consider this: Ross "destroyed many a metal file and saw blade" while shaping 500 of these mushroom bricks into a six foot by six foot archway. He hopes to destroy many more tools by one day building entire homes out of mushroom bricks.
And my parents thought I was nuts when I told them I wanted to live in a mushroom just like the Smurfs.[Time via Futurismic]

Ok, ok. So I'll have to correct the gender on the card, but come on! No product is perfect. [Etsy via The Daily What]

HTC HD2 Gets In On the Kickstand Craze That’s Sweeping the Nation [Kickstands]
Kickstands are enjoying something of a renaissance lately as tablets have jumped to the forefront of everyone's attention, so it's only natural that the HD2, the most tabletesque of smartphones, is getting a combination kickstand/battery pack of its own.
The battery definitely adds some bulk to the skinny HD2, but if you're looking to take advantage of its 800x480 screen to do some video-watching on the go, then an extended battery and a sweet kickstand are two things that could suit you well.
Taking part in the zeitgeist will only cost you £41.11 when the battery pack is available in March. [Cool Smart Phone via Engadget]
