Petrol saving

Time to fit a sail to your R/Hood mobile ---- 12 metres/second down in sunny monsoon rain weather ---here in Cornwall.

How big a sail would a 3 ton land rover need? It is windy most of the time here in fenland but generally blowing the opposite direction to which I want to go and it's difficult to tack with a dyke either side of the road

Think rotary sail --- vertical or horizontal axis --- drives the diff.  Heavy load -- flat ground -- heavy horses & blooming roses.

Hmm,

I drive a lot for work.. But my expenses stay the same.

Been looking at 50cc mopeds AGAIN

You'll need a much lower ratio in the hood box.
