30 Year Battery Life

http://www.nextenergynews.com/news1/next-energy-news-betavoltaic-10.1.html

Think of it as a solor panel, but instead of sunlight it uses electrons that are flying through the air. This sounds really cool, I wonder if and how this could be used on solor cars. Instead of having to worry about sunlight, this could be used instead? Think of this use on laptops, and other devices would be nice too, I'm sick of the 3 hour battery life.

Expect to see these in 2-3 years.
