    We already have power plants that run on gravity. They are called hydro-dams. The sun vaprorizes water. We dam up the rivers and streams that collect the water and use the head-differential to power turbine-generators.

    Typically when people say "gravity power plant", they mean a crackpot perpetual motion machine that uses unbalanced wheels or something of the sort. This particular video says nothing at all about how the power plant gets its energy, so we really don't know if it is something mundane or a crackpot perpetual motion machine scheme that doesn't work.
