You know I am not totally against conspiracy ideas when it comes to the drive for profitable energy resources verses safe and responsible sources. So thinking along that line what sort of reasonable ideas have you heard about? One example is geothermal energy using temperature differentiation underground verses above. Several ways to harness this principal. Also solar and lunar magnetism. Quick example: A massive floating dock off the coast that is tethered to a cable system that holds a steady location however the cables are attached to also very massive generators so that when tide comes up the cable is pulled spinning turbines. I remember that one from years ago in Popular mechanics. I sat on a plane discussing for three hours during a flight a fantasy island idea self powered by this as well as solar and geothermal power. Kind of neat when you have nothing better to do as a conversation piece. The two others were engineers one in the electrical field and one in thermal dynamics. So they had great input as we just kept it going.
