Maybe there should be a way to charge a flywheel with a cranking system.
What you’ll need to make this with is:
1 Wood handle (crafted in craft bench with 1 wood)
An iron block
Then to crank it you just press the cranker and you’re blockhead will start working.
This item will have ware over time but this will take the time it takes for at least 3 solar panels to charge a flywheel.
If you’re blockhead gets tired then you will not be able to use the thing.
So you like the idea?
