The premise of the “Mr. Fusion” device was that it used cold fusion to produce power. Cold fusion is a hypothetical source of nuclear power that would occur at or near room temperature. It’s been pretty much cast out by the scientific establishment.
The Hydrogenics fuel cells are an alternative energy technology that generate electric energy through the reaction between hydrogen (or a hydrogen-rich fuel source) and oxygen. These devices are particularly interesting due to high efficiencies relative to traditional combustion engines and low emissions, producing only heat and water as waste products.
I personally feel that technologies such as these are more promising than any advances in battery technologies we’re likely to see.
