Looking back, but a great idea that could have come from the 2020 summit, could have been "solar powered speed boats", along with solar powered, 8 cylinder cars ===========================================
Hi Fillip,
We do have sailing boats.
America Cup catamaran v trimaran are 90ft. long and can do 50 knots. Yes, 50 knots.
What if a billion chinese want to start caravanning, or go boating??? - surely, they are entititled to have 6 cylinder (or 8 cylinder ) vehicles, just the same way, that the people in the gluttonous west are.
You can only have what is available to you, at the time.
I read this some where ages ago;
My grand father rode a camel, I drive a Rolls Royce, my grand son will ride a camel.
