Gadget's and their batteries

The new iPad boosts some great features - retina display, higher graphic performance, 4g connectivity etc.  Now all this is nice but what is nicer is the battery life claimed on it. All this and yet a battery life of 9 hrs is great. Of course there is a secret - bigger denser battery. Knowing Apple, they have probably patented it already.

Today's gadgets (smart phones, tablets etc.) are very smart and power hungry. My android phone and iPad are no different. Since I carry my phone around, I always keep a charger handy with me. I am even considering buying a travel battery pack (something like this but maybe of more capacity. May be someday.

Couple of days back I came across some news on silicon nanowire based battery which can hold 10 times that and tweeted about it. Now this was amazing news. 10 times more battery life will be dream come true. But then I noticed that the news item was from Jan 2008 or earlier. What happened after that? I did more digging...
Amprius is the name of the start-up which is working on this and I found an article in GigaOM for a later date (late 2010). It talks about work still happening on the technology to commercialize it. The start-up is backed by many venture capital firms and Dr. Eric Schmidt (I wonder who is that now). Also found this nice graphical piece of writing which explains the technology in simple terms. The amount of increase it can give (whether 10 times or less) is still under question but even if we get 3 times more that will be good.

If this start up makes commercialization of this technology viable then every gadget maker worth their salt (read Apple and Google) will be behind them. Now will some Dr.Schmidt have any say in the matter.

For me, I hope this technology does not get stuck with one of these big players. This technology can make a great impact to on our lives. So what do you think!
