“Flooid Power” versus the Laws of Thermodynamics

Here’s Flooid Power, a renewable energy idea based on the claim, “(We use) energy generated by a force that’s not going away anytime soon–the gravity inherent in Earth’s mass. Flooid Power uses displacement and buoyancy to generate affordable, continuous electricity for homes and businesses — all within a self-contained, non-polluting unit that pays for itself in under 3 years.”

In other words, they believe they can get more energy out of releasing a fluid from a height and letting gravity bring it toward the center of the Earth than the energy required to push it uphill in the first place.

Ah….no.
