Creating Hydrogen With (Very) Hot Water

carbonman writes "NYTimes is reporting that a public-private research team will announce on Monday that they have discovered a new technique to produce pure hydrogen that is far more efficient than conventional methods. The advance could be a significant development in attempts to realize the dream of the hydrogen economy in taking gasoline-powered vehicles off the road, and without releasing carbon dioxide emissions that are linked to climate change. It does, however, require the use of advanced high-temperature nuclear reactors, none of which have been built on a production scale before." swiftstream adds a link to the same story at the no-reg Indianapolis Star, and summarizes the method as "electrolysis of very, very hot water."

    Is it just me or water can't be very very hot? At about 100 degrees Celcius, it vaporize... are they doing electrolysis on hot vapor? If so, can their tech be called Vaporware? :)

      I'm pretty sure you mean "at standard pressure". It's very difficult to get water to be at 100 degrees Celcius and at standard temperature simultaneously. :-)

    If, he thought to himself, such amachine is a virtual impossibility, then it must logically be a finite improbability. So all I have to do in order to make one, is to work out exactly how improbable it is, feed that figure into the finite improbability generator, give it a fresh cup of really hot tea ... and turn it on!

    You don't want a ship, you want a yellow submarine.

    Speaking as someone who has used hydrogen as a furnace atmosphere, if I had considered it as both safe and simple I suspect I would not be around to write this. I suppose if nuclear power at sea is safe and simple then everything else on earth must be even more so.
