A 20-year battery: BetaBatt

I think this is so cool - finally something niffty in energy technology. A startup is set to unveil tritium-powered batteries, likely to make them the first to commercially develop atomic powered batteries for the masses. The great thing about this technology, is that it won't be spreading dangerous radiation around (same stuff used in glow-in-the-dark watches), but will provide us with long lasting, efficient power sources. I wonder if this type of battery could be used for electric cars?!
