"where are you going to find enough land area around existing sources of CO2 to build acres of PBRs?"
Answer: In nearly every town in America.
Wow gumby, I thought with all your self-proclaimed DD skills, even you would be able to cobble together a couple hundred acres with CO2 sources. Maybe you could post some of those sweet google earth pictures of the sites, too.
- Power plants - Steel Producers - Iron Producers - Cement Manufacturers - Solid Waste Combustion - Lime Manufacturers - Aluminum Production
Somebody stated a while back that Fisher was getting his CO2 for $1 a pound. At 2.2 lbs CO2 per lb of algae produced I wouldn't think the cost of buying it commercially would be prohibitive. The 2.2 lbs of CO2 is a number waved about by algae promoters, so it might be inflated.
We dont have to be near a source of CO2. We can bottle the CO2 to a site and sell the carbon credits to anyone we want. They pay for the CO2 we use and the CO2 comes from the air we breath. The client issues the CO2 into the air.
That is how carbon credits work. The company who buys the credit doesnt need to put their own personal CO2 into a system.
