Hydrogen cars...


Recommended Posts

K, go and check out the site http://www.gm.com/company/gmability/enviro...c/indexpop.html and on the bottom right corner of the flash presentation click on "part 3: Fuel cell chemistry" and go through the demo.

Now the problem I have for this presentation is that when the electrons of the hydrogen is broken up and used for the motor of the car how can there be electrons left to create H2O? I mean doesn't the motor use up the electrons? :blink: :wacko: :unsure:

i'm almost certain electrons don't get "used up" as such....

however, in case they do, wouldnt the cathode or anode give more??

i dunno, just trying to help :)

Fuel Cell is great technology, much cheaper then fuel.

It has a couple of major obsticles:

* Oil companies. The true super power. They will make it hard for people to buy and use fuel cell cars, they have already stopped all other alternatives to petrol, they will do the same with fuel cells.

* Instabilty. Hydrogen is un-stable and if it was to be ignited there would be a massive explosion. Much easier and safer escaping from a car that runs on petrol rather then hydrogen.

Fuel cells in laptops excite me. The only thing i dont like is the possibility of the battery exploding. I might skip the first generation of fuel cell notebooks and let the earlytechnology adopters get blown up. Then I will buy one when they're definatley safe.

rofl, aren't you nice :p

Indeed though, its intruiging technology but I doubt if cars will ever use it. A simple, small rear-end accident, tiny spark, and boom--everything in a 5 yard radius engulfed in flames. Petrol on the other hand creates much smaller explosions, and has more tolerance to sparks.

Are you aware there are already a few test cars on the roads and the first fuel cell "station" is already in use in the U.S.?

Google it. You'll find the news articles.

getting back to the question, I guess I'll explain it briefly (gotta go to work in 3 minutes so I can't do it technically). The electrons DO NOT get used, BUT only their energy does. Energy is released during the conversion of hydrogen to water and the car uses that to power it.

You can actually think back to the momentum engines and then think about energy being constantly introduced to the system and then you'd get a basic understanding of it. If you don't know what a momentum engine is it's basically a metal ball attached to a rod that is spinning at a focal point inside a vacuumed out area. The energy doesn't last forever and you will need to get the ball spinning again, what get's it spinning? energy.
