Homemade gravity energy storage

What is gravity energy storage?

It involves lifting a heavy mass during excess energy generation and releasing it to produce electricity when demand rises or solar energy is unavailable. The types of weights used are often water, concrete blocks or compressed earth blocks. Unlike pumped-hydro energy storage, gravity energy storage offers more flexibility in site selection.

How does a gravity battery work?

So, for this concrete gravity battery, the electrical energy goes into a motor to lift a mass a certain height. When you want to get the energy out of the battery, you use the same motor to lower the mass back down to the ground, causing the generator shaft to spin and create electricity. There's your gravity battery.

What is energy storage technology & how does it work?

It is a new technology that stores energy using gravity. How does it work? It involves lifting a heavy mass during excess energy generation and releasing it to produce electricity when demand rises or solar energy is unavailable. The types of weights used are often water, concrete blocks or compressed earth blocks.

How do you store energy if you lift a mass?

The more mass you lift, the greater the stored energy. The higher you lift the mass, the greater the potential energy. If you increase the gravitational field—oh wait. The only way to change the gravitational field is to change the size or mass of the Earth. Forget that part. OK. You lift some mass and you can store energy.

What are the different types of energy storage?

The types of weights used are often water, concrete blocks or compressed earth blocks. Unlike pumped-hydro energy storage, gravity energy storage offers more flexibility in site selection. A typical setup involves a heavy piston within a fluid-filled cylindrical container.

How do you change the gravitational field?

The only way to change the gravitational field is to change the size or mass of the Earth. Forget that part. OK. You lift some mass and you can store energy. That's great, but how do you get the energy back into something useful?
