Frankly a good point, Drakkith. Does that put the final nail in the coffin for the gravity battery idea forever? Any possible alternatives from anyone before this thread ends?? Frankly if there's one thing I've learned it's the enormous power even a hashed-together product like the power wall...

Perhaps too simple a way to put it... As I understand flywheel technology you are either limited by friction losses through a mechanical bearing or hampered by production costs for a magnetic/superconducting bearing. Then there may be energy loss through counteraction of precession. With...

Very good point, but aren't kinetic energy systems much more liable to losses? Perhaps not an issue for short term local storage...

Sophicentaur, I really like your ideas! Personally I live in a 150 year old house in the U.S. South that solved heating and cooling issues a different way (solid walls, shade trees and french doors perpendicular to the prevailing breeze) but I realize we aren't that smart anymore. In the...

Nidum - the concept is to create a 'gravity battery' competitor to the Tesla power wall: same reasons, same motivations. The Tesla concept intrigues me because it shows the way to a more robust power grid with diffuse generation and storage, but the material costs are high. I am not a DIY...

Hi All, this question has been thrown around before but never fully answered so I'll put it very simply and cut out the ponderings: A 'gravity battery' could be created by using an energy source to slowly lift a large weight (using gearing or pulleys), then discharged by lowering the weight to...
