Comment on Gravity Light - Alternative form of lighting to replace Kerosene

Comments

Cool idea. It looks like light itself needs some work though. The light is bright, but it doesn't seem to shine in a very efficient or useful way.

I think that'd be easy to fix though.

This has me wondering how much energy a larger scale application could store and what its efficiency would be.

At larger scales, you are typically limited by the efficiency of whatever is lifting it. A large generator can convert kinetic energy to electric energy with very high efficiency (over 95%).

Also this is very poor energy density each kg moved 1m results in 9.8 joules or ~2.7e-6 kWh. So one metric ton moving 1km would generate 2.7 kWh.
