Dennis, check the Valcent link at post 3. They’ve beat those problems.
I've been to that link and can't figure out what their game plan is. Can you summarize it?
It seems to me they propose to hang plastic bags of algae out in the desert. Racks and racks of them covering hundreds of square miles. This sounds preposterous.
Then the stinking algae is taken from the bags and made into petroleum byproducts?
