Hello I have two questions that have been bugging me.
Here is the situation that involves power generation. Let's say a magnet is spun with a wire coil surrounding it ( a typical generator) in a vacuumed container in freefall ( such as satellite orbiting earth). Wouldn't this create a virtually unlimited source of power until friction caused by subatomic particles stopped the magnet?
Another question. Why are electromagnetic motors used more frequently than electrostatic motors?
I have tried to find the answers to these questions everywhere to no avail. Any input is appreciated

1 You brake the magnet when you exract power from the wire.
2 Some electrostatic MEMS motors have been built. Microwatts of power there. More torque from electro-magnetic systems.
3 Accept that there is no free energy.

There are already some prototype flywheel systems where the flywheel is in a vacuum and uses magnetic bearings. They will spin almost indefinitely until power is extracted. Someone was experimenting with using one in a hybrid car instead of batteries. But then, maybe there are some commercial versions of these around by now.

Can't imagine that being worth the effort. Most put out DC and invert to AC or put out whatever, rectify and invert.
