Mechanical Energy Generation

Commenters brainstorm impractical or humorous ways to generate electricity from mechanical systems like flywheels, reverse motors, wind-spun objects, lifted masses, and human-powered devices, often critiquing thermodynamic losses and perpetual motion claims.

Throwaway idea: Maybe it can be an energy-storage flywheel at the same time?

I wonder if this could be harnessed to be used as some sort of physical force generator.

Sounds like a great way to collect wind/solar energy...

Would save even more energy if they were attached to a generator...

kwhitefoot • Mar 24, 2019 • View on HN

My guess would be that they use the motors as generators.

Maybe they pee onto a turbine to recharge the battery.

seems the water could be a secondary energy source, and the cable energy wouldn’t be wasted, thats just more mass to lift and drop.

You could always generate the power for the compression using wind.

How about using these as solid state wind turbines to generate electricity.

Spin them all up when the wind blows and convert their kinetic energy to power during a lull.
