tidal generators and conservation of energy
Posted: Sun Mar 01, 2020 4:35 am
If the moon's gravity produces tides by moving water, and that kinetic energy can be converted to electricity, and if energy cannot be created or destroyed, what is losing energy in order to add kinetic energy to the water in the ocean? The moon doesn't seem to be losing any energy. It's not falling out of its orbit. Where is the exchange of energy that should be happening to prevent power generators that use ocean tides from being perpetual motion machines?
