Intervision is to take old tech. and customize it.
Look at a interduction motor it uses bearings..
Induction motors use shorted wire loops on a rotating armature and obtain their torque from currents induced in these loops by the changing magnetic field produced in the stator (stationary) coils.
Note that this simplified motor will turn once it is started in motion, but has no starting torque.
Various techniques are used to produce some asymmetry in the fields to give the motor a starting torque.
The Interduction motor can be used to create Free power..
Just ask something and I will get back.
