Splitting Water with Sun Power Means Cheap and Easy Hydrogen Fuel

Any time someone says that something is cheap and easy, it's NEITHER.

Ugh. I get so tired of this inane crap but to the under-informed "public" it has an air of believability that creates a false sense of feasibility. If the ROI was there, someone would be doing it already and you would see these solar concentrators popping up all over the place.

Rant over.

I don't see why you're so "ranty".

All you need is;

a tracking solar furnace ("Stay-Kleen" model, obviously)

with a high temperature vacuum/pressure flask,

a chunk of purified sintered cerium,

a triple distiller,

a metered injector

an oxygen inert vacuum pump,

a hydrogen vacuum pump/compressor,

suitable hydrogen leak-proof storage,

a temperature cycling system,

appropriate sensors, programing, servos and motor drives

And with that you get 1% efficient, hopefully 20 times more, conversion at source - the latter of which might get enough hydrogen to run all the above stuff.

While I tend to agree with you on the ROI, I also think that "solar H₂"is a good idea. We had a rather long discussion on hydrogen as a fuel back in October 2008 which is worth reviewing. http://cr4.globalspec.com/blogentry/7032/Where-Are-All-The-Hydrogen-Cars
