Ok, but what catalyst are they using?  Moly-B?  Because if so, that's pretty good.

Also wondering about the alkaline water.  Is it pH neutral water just becomes alkaline with green biomass or do they treat it first?

It could never economically replace nuclear, petroleum, wind, and solar power generating technologies not to mention the infrasturcture just isn't there.  This is a non-starter and besides, it scares the horses.

You left out the fact that coal is still cheaper.

Not to mention it will drain the sun to death

New video by Thunderf00t where this is "busted" in 3, 2, 1...

Yeah, but will it put people back in coal mines?

And yet you still are going to drive that oil-fueled car of yours.

Only if it defies the laws of physics.

These aren't by any chance the same people who keep claiming to have invented a method to turn garbage into oil, water and a metal sludge, is it?

Probably not. Photonic extraction of hydrogen (or splitting of water) using nanoparticle catalysis isn't actually all that new or uncommon-it's REALLY heavily documented. This is just apparently a more tuned up version of it.

There's a few mechanisms by which nanoparticles can do this, too. I'm only somewhat familiar with the ones involving surface-plasmon resonance (Noble metal nanoparticles, under proper illumination, can inject hot electrons or 'hot holes' (depending) into an adsorbate, which can affect some REALLY interesting catalysis by farking with bonding and anti-bonding orbitals.)

I know you can use Titanium Oxide, too, but I'm less clear on that process (I believe it's *NOT* plasmonic in nature. It is still hot-carrier mediated, it just uses a different mechanism to generate the hot electron or hot hole.)

Great, now FCEV advocates will misuse this as evidence the next time I have a "debate" about the absurdity of the technology.

How much success have you had so far in stopping fchv progress?  As far as I can tell, it is continuing to move forward.  More HRS continually being added, and makers keep developing more refined models.

It is good for you to have a hobby, though.

Because you're smart, like the rest of us!!

Good luck, we're all counting on you.
