Stanford researchers have found a way to use silicon nanowires to reinvent the rechargeable lithium-ion batteries that power laptops, iPods, video cameras, cell phones, and countless other devices.
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.

Their existence is old news. Any word on when (read: if ever) they will be available?

This story isn't *THAT* old.. At the silicon valley EAA meeting in January it was new, and Crusher was there (same time as I) and he brought this story up as a new bit of news. Someone in the audience knew the researcher (er.. the SVEAA meeting is held within walking distance of Stanford) and related a) this research was only one end of the battery (either anode or cathode) and not the whole battery, b) they guesstimated 3+ years before having a full battery system.

I would agree - probably 5-7 years before it can be scaled up to production levels? Battery technology is always slow to come about. Look how long it took for LiFePO4 to become viable since Dr. Goodenough patented it almost ten years ago. The Nano Wire story is just beginning, and growing carbon crystals in a laboratory on a small scale is a totally different proposition when considering these fragile branches must be able to withstand the shock & vibration of use in an EV. Many obstacles are in front of these pioneers, and I hope they are successful, but for now we all have to grab the available new tested technology to advance the Electric Vehicle movement.
