I recall the largest moving land machine in the world - German strip
mining machine run on 36 electric motors. It strips the surface of the
earth and takes in coal (energy) this goes down a flexible conveyor belt
and to a local power station. The machine has a long flexible power lead
from the grid which is fed from the local power station. A perpetual
motion machine? Probably, as the output is fed back to the input to keep
it running (although men have to operate it)
Thanks for demonstrating your lack of understanding of physics once more.
That device runs on the energy produced by burning some of the coal it
transports. Or perhaps you'd think a diesel tanker powered by perpetual
motion too since it carries more fuel than it uses?
