Let me ask you Jesse do you suggest any substitute that we can turn to
for
transforming world civilization to clean power? The only significant
thing I
can think of, would be hiring Craig Venter to produce some methane or
hydrogen
maker, that can, if necessary convert sea water to fuel.
You seem ignorant that converting sea water to fuel takes more energy
than you
can get from burning the fuel (hydrogen). So you still need a clean
energy
source to do the conversion.
This would be a possible way of creating fuel for easy transport. One of
the big
points about petrol is that it's very transportable. The best solution to
the
world's energy problems imho would be to find a method of extracting carbon
dioxide
from the air and converting it plus water into petrol using solar power.
Carbon-neutral petrol and we don't have to rejig all our existing transport
systems. If we can extract more carbon than we use we might even cool the
earth too.
Is that not what the plants are doing, all the time?
Yes, but unfortunately the whole process takes millions of years.
That's to produce oil and coal. But we could just burn plants - which we once did. Or we
can extract liquid fuels in various ways from plants (e.g. ferment to alcohol). But these
methods are, so far, very inefficient - less efficient than wind or photovoltaics. Maybe
genetic engineering of algae to produce oils will make it practical.

Can we do better, I mean today?
Not at carbon sequestration, but to achieve a reduction in CO2 by growing plants we
would have to stop using cars and power plants and so on. The reason I gave the above
suggestion is that if we can do it, it would enable us to be carbon neutral without
giving up our civilisation to do so.
