I recently had a visitor, a brilliant guy from Toronto, stop in for a visit. Among the many things we discussed were the tar (oil) sands. He said the problem with the oil sands has been the carbon waste in separating the carbon from the oil, but new technologies have now made the tar sands much more valuable than other crude oil because once separated, both the carbon and the oil can now be used for energy with zero waste. These new technologies are already being introduced into the aircraft industry to fuel the newly designed jet engines. He said check out SABRE ENGINES.
He was talking WAAAY over my head but that was the gist of the conversation, so take it FWIW, and he was not trying to sell me anything. LOL!! All the best …Silverngold
