help*- let cars use less natural resources
Hundreds of magnets in cars helping to fuel cars
I hope this all makes sense. I tried my best

The "idea of of perpetual motion" doesn't work - it is a defective old idea.
There are trains that use magnetic levitation to keep the friction down by floating above the track. There are ones that use a moving magnetic field to propel trains along a powered track. Electric motors that drive most trains use electro magnetism for motive force. BUT there are none that use magnets for perpetual motion.

Perpetual motion is impossible. But there are "mag lev" trains which are driven my constantly alternating magnets. But these require electricity, so they cannot be perpetual (which is a closed system that doesn't require energy to continue moving).

I believe that perpetual motion is
possible. Magnets are the key.
