Nigel Goodwin said:Was it you who was on about this before? - solar panels are inefficient, and electrolysis to produce hydrogen is VERY inefficient - it's really an EXTREMELY poor way to try and store energy, which is what you're actually trying to do!.

The germans have made a study about harvesting solar energy in the sahara where the sun would be used to drive turbines to make electricity and transported to the european grid.
Oznog said:What you suggest has critical problems:
1. Making hydrogen in an industrial setting is fairly efficient regardless of the power source, however, burning hydrogen in an internal combustion engine is no more efficient- probably less- than burning a comparable amount of gasoline energy. Right now if you used grid electricity, which is mostly coal/nat gas fueled, it would result in more emissions than running the cars on gasoline. Sure if we had free, unlimited solar power that would be nice. First thing I'd do is replace all the coal-fired plants.
2. Unfortunately, hydrogen is extremely difficult to store in large volumes. This is already a killer problem for fuel cell vehicles which are many times more efficient and require many times less storage capacity for an acceptable range. The practicality isn't there.

Global warming? I'm pretty sure the planet was much warmer before the Ice Age, the now. I believe the planet is recovering from whatever catastrophy that caused the cold, man has little to do with it, and not much we can do to prevent/reverse/slow it down. Some people need to control everything and everybody around them, really pisses them off when they can't...
My interest in enviroment, is that this where we live, it's not a toilet. Why live in filth when we have other choices? I'd like to see less stuff made for limited use, then later dumped in a hole. Why use so much plastic, when paper would work just fine.
that's wrong.you know all that carbon in petrol does not make power ?

Thunderchild said:erm I'm still waiting for some figures people..... you all came along with lots of cons and not much info to back em up
No, it's the carbon that burns while the hydrogen is chucked out bonding itself with oxygen making water.as far as I know the hydrogen burns and the carbon is chucked out bonding itself with oxygen making CO2
I'm sick of some of the myths propagating about carbon dioxide and fossil fuels.Thunderchild said:please be more specific, as far as I know the hydrogen burns and the carbon is chucked out bonding itself with oxygen making CO2, so not only do we make a poisonous gas but we rob ourselves of oxygen. By making the hydrogen from water we are also putting into the atmosphere the oxygen it will need to burn
Thunderchild said:so why the CO2 then ? if the carbon burns into energy how come it comes out as CO2 ?
