The Two Day Battery

Battery Stanford researchers have figured out a way to incorporate silicon nanowires into rechargeable lithium ion batteries and extend their life from 4 to 40 hours. The work, described in a paper in Nature Nanotechnology, could lead to iPods, laptops and camcorders that could be run nearly for an entire weekend without requiring a re-charge. Of course, this is still in the lab stage, and there are undoubtedly quite a few steps and hurdles between the campus and commercialization, but we're optimists. So, here's to the end of the ABC (Always Be Charging) Rule of electronics.—Gregory Mone

Charging electronics? A new battery technology comes out and all you can think of is your lap top and camcorder? Hello? How about the electric car?! How about storing renewable energy sources for use in your home? The world has been dreaming up all sorts of great advances for a greener world, but always saying "someday, when we get better batteries." Sheesh

And Im sure the next gen tech that comes out will have greater demands on battery power. Once again negating any battery advance. And the cycle repeats :)

I AGREE WITH THE POST BY LARRY - WHAT A POORLY WRITTEN ARTICLE - DOES THIS HAVE AN APPLICATION IN AUTOMOTIVE?

I am sorry to say, that is technology if it does work will never be seen by the public for real use. The oil companies and auto industry will buy and then shelf the technology. They have done this many time before, Closed Tucker, bought any patent or a process for a the very high mileage carburetors, dis-mantled the last electric car program that was working. The corruption goes to high into the government to allow this to happen. It would being world war since oil would no longer me needed as it is now and the would economy is based on greed and oil.

we could also use them in houses taking power frow solor panels and also at place like hopstails and the they could last a lot longer then with the gentaor and it would mean less wear on it

"Larry" is right on the money. We've come to expect that our computer chips will double in performance every 18 months, yet when it comes to batteries, increased fuel efficiency for cars, etc., we've usually dragged our feet, moaning about how difficult it will be to come up with an improvement and how expensive it will be. Let's bring the same optimism that we've had toward increasing computer performance to these other important technologies such as batteries, fuel efficiency, etc.

There are encouraging signs: while the Big Three car companies are lobbying government to keep our cars as inefficient as they are now and whining "Oh, but it's going to be sooooo expensive to make a car more fuel efficient" other companies are going out and *doing* it (VW with their 70 mpg Polo clean diesel, or the various X Prize competitors striving for 100 mpg or Google's fleet of plugin Priuses, for example). And Nanosolar, with it's breakthrough 99 cent/watt solar panels, or the change from NiMH batteries in our phones and power tools to the much better Li-ion batteries over the last few years, which are now being tried in hybrid and electric vehicles.

We can create change. We can demand change from government and big companies. If we want, and are determined and optimistic about our collective ability to discover new and better things, the batteries we use today, for example, will seem so stone age 10 years from now.
