Any thoughts on a way to generate electricity on the sea floor? It has come up before for a few things on electricity use underwater and most things have tended toward a wave based or ocean current solution. But what about on the floor itself with minimal current?
Could geothermal be used for a Stirling engine? How deep does one have to go into the earth to get a significant enough temperature difference? And would the temperature difference dissipate?
Any other thoughts on this?
One application I can see this for is Biorock for artificial reefs.
