The Stirling Engine for free electricity..

so I was thinking about the Stirling Engine.. and re-watched this video

HERE

In Scotland we could use the decommissioned oil rigs to create massive engines!

then channel the electricity home via lines..

Water the cold heatsink and the heat being the sun from a large panel (the engine would be upside down)

hmm.. I've got a headache just now so maybe attempt a drawing later..
