Can you or anybody else think of any other energy technological breakthrough in the last 20 years, or maybe more, that's....
1. Green
2. Efficient
3. Has a high return on investment
For example, solar and wind are green and efficient, but their return on investment are pretty poor.
So much money is thrown on these technologies including T. Boone Pickens by the billions just to make whatever dent anybody can in oil importation regardless of the efficency or how terrible the return is on investment.
P2O is green, super efficient, and has a massive return on investment. Al Sousa is just the start IMO.
