View Full Version : Renewable energy idea, anyone?

I would like to build an electricity generator compressed air and water. The idea involves submerging a large hybrid tank of compressed air / turbine to deep a pre-determined depth. Attached to the compressed air tank, there is a pipe extending toward the surface in which and advanced design of water turbine is capable of fully exploiting the extreme pressure of the gas trying to escape to the surface. The best part is even though the gas meets resistance to the turbine trying to spin, it is constantly regaining momentum and energy all the way to the surface.. so the process of harnessing the energy can be repeated again and again to the surface. This idea sounds completely plausible as the energy gain occurs with the assistance of gravity.. both, when the tank is dropped and even once it is depleted. When the gas escapes the tank it will not need much to move the turbine. A small amount will pack a powerful punch, infact the deeper you drop it the higher the potential of energy. Have you ever tried to submerge a beachball to the bottom of a pool and let it go, watching it shoot out of the water? Imagine that amount of gas trying to escape depths of 1000 feet. The buoyancy of the deleted tank makes it easy to haul back to the surface to recharge it with compressed air, so recharging our energy device is actually viable.

Brandon, welcome to the forums!

You do realize there's no free lunch when it comes to energy, right? All the energy you may be able to recover from that air coming up first has to be put into that tank; first by compressing air, then by lowering it (against buoyancy). At the end of the day you will get far less energy out of this then was originally put in.

Such is the harsh reality of energy... TANSTAAFL (as Heinlein put it).
