In response to Bruce, I recently watched an article that basically said that petrol powered vehs. will still be around in 20 years, by which time this CO2 being the devil, folly, may have "cooled" a bit?
Go to You tube and watch "Why Gas Engines Are Far From Dead - Biggest EV Problems"
Our govmints are yet to see the light (Btw, I can't even talk to my sons about this, so I am expecting to get dumped on from some quarter)
Mean while, the anti everything crowd will still be there harassing us.
