I've heard that this splendid option is available with a set of sails that in turn 
can be connected to your dyno hub to generate electricity to power your microwave, fridge,electric blanket and coffee machine. Sorry, free hit, couldn't resist Just watched the Boy who harnessed the wind film.😁

My camera merchant back about 1980 was an elderly chappie whose passion was landsurfing. His surfing machine was towed behind his car to a goodly stretch of beach, and he and the other aficionados of land surfing would race up and down the beach. Even a small armada of them were a heartstopping sight.
