- TL;DR Summary
- I am designing a gravity-based electricity generator using a 500 kg mass and exploring various mechanical configurations to convert gravitational energy into electrical energy efficiently. I am considering setups like pulley systems, piston mechanisms, compressed air systems, and piezoelectric approaches, with motor options ranging from 10 kW to 100 kW. I seek advice on the most effective setup and motor recommendations to maximize energy output.

Hello community,

I am currently designing a gravity-based electricity generator and exploring the feasibility of different setups using a 500 kg mass. The core of my project is to harness the potential energy from this mass as it is lowered from a significant height. I am considering several mechanical configurations to convert this gravitational force into electrical energy efficiently.

Here are the mechanisms I'm contemplating:

Pulley System: Utilizing a pulley attached to a generator, where the descending mass generates rotational energy. What would be the optimal gear ratio and mechanical setup to maximize efficiency in this configuration?

Piston Mechanism: Implementing a piston-like setup where the falling weight raises a lighter mass, creating a continuous cycle. How practical and efficient is this method for sustained energy generation?

Compressed Air System: Leveraging the weight to compress air, which could then drive a turbine as it decompresses. What are the potential energy losses and efficiencies expected with this method?

Piezoelectric Approach: Using piezoelectric materials to convert the mechanical stress from the weight's impact into electrical energy. Given the large scale of the mass, is this method viable?

Additionally, I'm evaluating the use of motors with different capabilities, ranging from 10 kW to 100 kW. Wind turbine motors that can generate 10 kW at 100 RPM are on my radar, but I am open to suggestions for other types of motors and methods that could be more effective by using 500kg of weight.
