There are thousands of varieties of green algae, and it grows in fresh water, sewage water, brackish water, salt and brine water, hot springs and arctic cold water.
A lot of green algae grows so fast if can double its weight daily.
The South Koreans were planting 85 thousand acres of a large type seaweed, which is considered green algae too, off their coasts. I have not heard any news about that project for a while.
There are varieties of green algae which consist of 50 percent raw crude oil by dry weight. This can be refined into petroleum type gasoline in regular petroleum refineries.
The algae cake with the oil removed has a high protein value and can be eaten. might not taste too good, but animals eat it and it can be made into protein powder and added to many human food recipes. As production ramps up, there will be millions of tons of it produced and used to feed starving nations. World side food production can expand tremendously. We can also double our current corn production totals anytime we have markets to sell it.
One of the technical problems in green algae utilization was that the best oil producing algaes are not the fastest growing algaes, so a lotta plant breeding is going on to produce better varieties, just as with corn and beans.
