Hasn't this already been debunked? They mainly forget to mention the fact that it generates only a few nanoamps.

This is a primary cell powered by radio-active decay, comparing it with a Lithium Ion battery is daft. It's no more self charging than an alkaline or Manganese Dioxide primary cell - it gets a a a one time fill of energy when it's made.

There are no figures given so I assume that the amount of energy available is very small, Radio active decay proceeds at its own rate, so the battery will last the same time if you use the energy or not.

The picture looks fake - why on earth would you put a battery in a 64 pin TQFP.

This might be a useful device in some applications - it's a shame that the PR people were allowed to write about it and obscure all the technical details with hype and silliness.
