Solar powered outboard motor

A regular reader of the blog has written to ask if the Salty John Perpetual Motion Solar-powered Outboard Motor has reached the production stage,

I regret to say that despite promises from EEC research funding agencies we have been unable to secure the necessary backing to move the project forward.

The idea, as you will recall, was brilliantly simple: Six garden solar powered lamps were strapped under a turbine. The heat from the lamps created an upward flowing air current which turned the turbine which, by means of a simple mechanical drive train, rotated the propeller, providing forward propulsion. A mirror focused the light from the lamps back onto their own solar panels creating a sort of perpetual motion.

The bureaucrats in Brussels withdrew funding claiming that perpetual motion was a discredited concept, but I think they needed the money to bale out Greece.
