Yes it works, but it takes a hell of a lot of engery to electrolyse water into Hydrogen and Oxygen.
Its the principal of several fuel cells which have been around for years.

I don't believe that for a minute - he'd have been bumped off before he'd even got to the media! Was it an april fools?

Brought to you by the station that brings you the Simpsons, you are watching Fox. It must be true .

I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

I was wathcing 5th Gear the other night and Honda have devloped a car that runs on the same system

I have seen a demo where water was split using a square-wave power supply - the gas was produced copiously with fairly low power input. The downside
was that the gas produced was a mixture of oxygen and hydrogen - ordinary electrolysis separates each gas according to the polarity of the
electrode.
It may be significant that his system produces a mixed gas...

I saw a program about a guy that did this years ago. Said he'd been targetted by all sorts to stop developing it as a commercial product. Said
the oil providers had made attempts on his life as his findings would affect them drastically.
Obviously the program didn't show exactly how his system worked but showed a "prototype". Although it does take a great deal of
energy, this guy reckoned he'd made it all happen without needing to inject huge amounts of energy into the process in the first place.
And the resultant by-product of running his "water car" on it was water therefore no polution.
I'm not a physics professor but it sounded too good to be true back then. Things may have changed however.

that is way out of date, fuel cells were invented years ago and bmw had a hydrogne burning car back in the late nineties.
in the end the power comes from the electricity supply and it isnt 100% efficient and neither is the power station that produced the electricity so in
the end these ideas are a bit flawed until we have a reliable source of green electricity ie nuclear fusion mostly likely.
there are london buses already running on this so whilst he may have patented the hydrogen welding (it will be a very specific patent) he cant patent
hydrogen cars. also hydrogen and welding is a big mistake as either excess hygrogen or steam will embrittle the weld.

If a decent source of renewable alternative to oil energy source was found and released the world economy would collapse, as it is so dependent on the
oil companies.
That is what they would lead us to believe anyway!

how about we use our home leccy supply to wind up giant rubber bands, then use them to power our cars all day? Thats sure to generate more power than
we put in...
Well, it might save on fuel duty somewhat - or more likely, incur it on the whole house supply

There was a feature on Fifth Gear the other night - there's a Japanese island somewhere that generates more hydro-electric power than it can
use, so they make hydrogen with the surplus.
The big manufacturers use the island to test their fuel-cell cars!

toyota have done it too. i have seen one of their hydro powered previas in their training centre. however dont think they will produce em as it must
cost loads!!!

It's no good to us. How could the government charge tax on water. - WATCH THEM TRY!!
