FWIW, the implications of this are massive! Take any charge capacity you're used to (6 hours talking, 10 days standby for a cell, 200 mile range for an electric car, 4-8 hours for a laptop) and multiply that by 10.
Electric cars with 2000 mile range? Pretty freakin cool!
the Tesla battery pack is about 900+ lbs for 200 mile range... Think 200 lbs for 400 miles or so. Pretty freakin sweet! The electric motor in the Tesla is much smaller and lighter than the engine in the Elise. Now we're talking a track ready electric car with the power to weight to smoke supercars.
this is real. I heard about it well over a month ago. Now, there are issues on turning it into a product. But since the Si Nanowires grow well on stainless, I can see this being done with roll-coating technology to make the stuff by the square yard in factories pretty much like they use for making the alumized films for the patato chip bags that look metallic (or those funky balloons). What is different is that growing the nanowires is a wet process (I think) that is slow compared to just vapor depositing aluminum in a vacuum vessel, so the web won't be going at 100 feet per second. But really, all the bits are in place to commercialize this technology, it's really just an engineering excersize now.
