Very interesting thread guys.
It will be interesting to see what developes in the next 20 or 30 years,
tho I wont be around to see it.
I also expect to be back to using a horse and sulky in my older age.

My offering for an alternative fuel engine, would have to be a 2 stroke
running on compressed soap bubbles !
Replace the spark plug with a PIN and there ya go.
Cheers.
