Gary,
Could these solar ponds be multipurpose say for Aquaculture (fish
farms). We are being told that fishing yields are way down.
If this acreage could be architected to perform a dual purpose of food
production and energy production it could be made even more
cost effective besides fish is healthier than steak anyway.

I am a big fan of methane-based energy and look favorably on biomass
too. Are these solar ponds sealed from the environment with lexan
plastic, which would keep out dust, fungus, rain, grass, bird droppings,
and insects? How much methane, in cubic feet could these ponds produce?
Enough to power a 100 million car fleet? Could the methane be converted
to methanol or should vehicles be run on CNG? Would such a technology be
"blown out of the saddle" with competition from Alaskan natural gas, or
the development of methane hydrates from clathrate oceanic sources?

<<Actually there is a solution very close to that. Creating methane in
solar ponds using engineered bacteria, put into the existing pipeline
system, sent to retooled refineries that convert it into propane or
octane, perhaps using some power from spike's windmills. Converting
short
chain hydrocarbons into longer chain hydrocarbons I don't believe is
particularly difficult (though I'm not a chemist). The hard part
(currently) is having a sufficient quantity of the short chain
hydrocarbons (which are currently all being pumped out of the ground
rather than manufactured above ground).
