Hydrogen

hi guys I've found this really interesting video podcast's feed about hydrogen as energy source and related Hydrogen Olympics:

Let the record show that hydrogen is not an "energy source" in that nobody AFAICT has found a source where molecular hydrogen can be extracted.
Rather, it's a means of storage of energy. A pretty diabolical one, at that,requiring very high pressure and highest quality piping joints and fittings (to avoid leaks). Not to mention that its range of combustibility in normal atmosphere is 5% to 95%. (Ask diesel submariners about what that means.)
Except for use in fuel-cells and rocket boosters, why bother?

.... economically.

There _is_ molecular hydrogen in the atmosphere, but only in tiny quantities. Extracting it would be like extracting Heavy Water from ordinary water. Far more costly than electrolysis. -- derek

Hydrogen isn't an energy source, it's an energy carrier, and not a particularly good one.

There is little interest is podcasts here. Come back when you wish to discuss something or ask a question.
