Why is it that environmentalists bang on about CO2 emissions??
But it is supposed to be more environmentally friendly to drive around using H as fuel?
H2O has a greater capacity to cause global warming, than CO2.
Think before you write :banghead:
The topic was based on vehicle emissions in the future, not natural geological events.
I didn't say a thing about CO2 emissions... I fully concur with you that H2O is a more significant greenhouse gas than CO2.
Even if every vehicle out there is H+ powered and only giving off H2O, though, it's still a smaller contribution than what natural processes are already contributing. That's my point, and what you weren't thinking of when reading what I wrote.
Now, to look at the other side: does that mean that additional H2O should be unregulated as exhaust just because natural processes contribute more? That's the question you were trying to drive the conversation towards...
The problem from my perspective is, there's always give-n-take. People push solar power, but the battery technology isn't behind it yet, the chemicals inside the solar cells mean you're mining some nasty things for the production of... wind power, ideal generation sites are in bird migratory routes, they have a decimating effect on bat populations, and the vibrations from them cause bee hives to scatter... nuclear, where are you going to put the spent waste? Hydroelectric, you cut off sediment delivery enrichment to downstream floodplains, cut fish migration routes, and fill in with sediment... Hydrogen, sure, sounds great having water as the exhaust, but you've got to get the hydrogen into a usable state beforehand, meaning you're expending more energy overall.
I think about energy issues a lot. It's my job, afterall.....
