http://www.nextenergynews.com/news1/next-energy-news-betavoltaic-10.1.html I cam across this article. It is horribly written from a scientific standpoint and lacks some necessary information on how the device works. But the basics are... Tritium is the beta source, porous silicon matrix channels the electrons to produce a usable current, and it has lifetime of 30 years. Issues I can see: 1) Containment of the Tritium. 2) How can you effectively convert betas to usable power. 3) How does the silicon produce a usable current with a great enough magnitude. 4) How much Tritium is necessary for the device to produce usable power for 30 years. If this thing pans out I see it being used in satellites far before you give people Tritium to walk around with. Another industrial issue would be the production of the Tritium as far as I know, Watts Bar is the only place in the US producing Tritium at scale (correct me if I'm wrong). After some discussion, this thread might have to go into the debunking repository as these claims seem rather far fetched to me.
