why? Posted July 25, 2006 Share Posted July 25, 2006 It's like the perfect accesory to environment caring Barbie. It is pretty cool BTW Link to comment Share on other sites More sharing options...
JTM³ Posted July 25, 2006 Share Posted July 25, 2006 Not sure if I should make a new thread about this or what so here goes... Is Hydrogen really a viable option? It's more explosive than gas isn't it? Sure, it'd be great...but can it ever be made viable? The main challenges in using hydrogen in cars are the very high costs and the low energy efficiencies; so far, there is not much likelihood of overcoming these challenges. Consequently, only a few demonstration vehicles have been made at high cost. See The Hype about Hydrogen and hydrogen economy. Link to comment Share on other sites More sharing options...
insane_alien Posted July 25, 2006 Share Posted July 25, 2006 this is where us chemical engineers come in, finding a way to produce massive amounts of hydrogen(or metal hydrides or whatever storage method they'll use) as easily and inexpensively as possible. it'll probably end up as electrolysis of water but have to wait on fusion power to be effective.

Guest_Jim* Posted July 25, 2006 Share Posted July 25, 2006 Hydrogen isn't the only fuel that could be used in fuel cells, I've also read about methanol fuel cells. A methanol fuel cell works like a hydrogen fuel, but carbon dioxide is also produced. However methanol is a lot safer to transport than hydrogen, since it is a liquid at room temperature, so for cars it would probably be a better choice at the moment, in my opinion.

Yeah, like hydrogen can ignite from an electrical storm several miles away and corodes metal?! Link to comment Share on other sites More sharing options...
CPL.Luke Posted July 25, 2006 Share Posted July 25, 2006 I've heard good things about thermal crackers that take advantage of nuclear reactors to break up the water molecules Link to comment Share on other sites More sharing options...

CPL.Luke Posted July 26, 2006 Share Posted July 26, 2006 essentially you just run water over a nuclear reactor and use the heat to break the chemical bonds. I think water breaks down at 2000 degrees or so but I'm not sure. Link to comment Share on other sites More sharing options...
