Nanowires Boost Laptop Battery Life to 20 Hours 238
brianmed writes to tell us that Stanford researchers have created a new use for silicon nanowires that promise to reinvent lithium-ion batteries. "The new version, developed through research led by Yi Cui, assistant professor of materials science and engineering, produces 10 times the amount of electricity of existing lithium-ion, known as Li-ion, batteries. A laptop that now runs on battery for two hours could operate for 20 hours, a boon to ocean-hopping business travelers. [...] The lithium is stored in a forest of tiny silicon nanowires, each with a diameter one-thousandth the thickness of a sheet of paper. The nanowires inflate four times their normal size as they soak up lithium. But, unlike other silicon shapes, they do not fracture."

How long before laptop batteries get classified as "munitions"?

They're going to put Extenze (and Viagra) out of business with a product like this.
On the bright side we won't have to see any more commercials of the chick with the freaky eyes.

If you have to ask you can't afford it.
2) How long does it take to charge
Not too long, plug it in and wait for the amber light to turn green.
3) How many charges can you get in its lifetime.
If its made by Apple you can charge it as many times as you want, but replacing it will cost about 82% of the original cost of the full price of the original device you bought it for UNLESS you buy an Apple Care Plan for 73% of the full price of the original device you bought it for.
If any one of those is a major deficiency, the technology will be worthless. Since they didn't immediately bring up use in electric cars, I'm guessing there's currently a fatal flaw that applies to one of those questions. They will ALL be deficient to one person or another...therefore the technology will be worthless in some aspect by someone. Why is it that people only want to use it in electric cars? I'm sure all the single and lonely women wouldn't mind having a device that doesn't quit on them before they're TRULY satisfied...which will never happen because women are never satisfied. Thats why its called a ball and chain.
My money is still on ultra-capacitors.
You fool. My money is in Gold because the Fiat System will fail at some point and you can't buy food with ultra-capacitors...
