He’s fine right until he talks about methanol. One reason methanol hasn’t really taken off is because someone noticed that burning methanol in an internal combustion engine grossly increased the formaldehyde exhaust of the engine. Whoops.
But it produces substantially less of other pollutants. How it compares overall I am not sure.
I think FIA or F-1 racing needs to be told...They run their racecars on Methanol.
