The difference between CO2 and H2O in the atmosphere is that H2O when pumped into the atmosphere cycles rapidly back out For example when they do space shuttle launches which relaeses vast amounts of water, it then rans. CO2 can happily sit in the atmosphere for centuries. The problem with the H2/H20 fuel source is getting the energy to make the H2.Pug wrote:
If you take the leap that CO2 is causing global warming (which I don't necessarily agree with), what happens if you replace CO2 with H2O?mikeyb118 wrote:
Ok to adapt the point of my post I pose this question. How are we to know and theorise the effects of introducing hydrogen vehicles upon the Earth climate if scientists are not even sure about the natural state of order and our own burden on the environment atm?
That's the question I'm interested in. The global warming debate about whether it's happening or not is covered elsewhere. I was hoping for something different...that's all I was looking for. I'm not trying to detract from your point, I'm just hoping for a discussion that isn't arguing about whether it's true/false/etc.

- What if? Hydrogen cars only / environmental effects
How about you ride your bike when you only have to go like... 15 miles, I can get places around town just as fast, and sometimes faster than cars when traffic gets bad.

it really changes nothing tbh, because the hydrogen is made at a power plant and then shipped out, but really you'd probably be better off with an electric car once batteries get better, because hydrogen would be inefficient to transport and there is a loss of energy when you convert water into hydrogen, and then hydrogen back to water...
