All this talk and no one even mentions the cold Hydrogen flame. Not even knowing about Thermo that's just ridiculous.
As for the discussion about using water for a car. If you pour water in your car and expect to convert it to Hydrogen through electrolysis, you have to supply the electricity. This means you either have to have batteries or a generator. So if you're running an IC engine on the Hydrogen from the electrolysis to power a generator, the electricity you get out is less than what's required for electrolysis. Simple as that. Has nothing to do with the energy being converted to a more useable form.
I hate it when the news publishes crap like this. They should get their stories checked by people who have a technical background so as to prevent spreading this nonsense.
