Magnet
All parts of the cylinder that fall in the greater gravity (magnetic)
(magnetic) level must be pushet out, as well. All the work, that a part of
cylinder gets when it's moving toward the greater gravity (magnetic)
(magnetic) level is needed when it is pushed back out of it..

Put an innertube on a wheel. Fill it two thirds with wather.
wather. Put an axle through it so it can spin. Now make another one like
like it. Now hold
the axels and push the wheel up against each other so that they can squeez each others wather to the outside. The results are that one
side of each wheel is lighter than its other side. That is why the
the wheel spins.

QZ: We are not using this type of vehicle because
a) perpetual motion is forbidden by the
Newton's Laws
b) police does not allow it
c) sitting next to a strong magnet is not good for the driver’s health
d) there are no such strong magnets so far
e) this vehicle is not going to start moving by itself, so it is not very
practical for plane roads. Can be only used to go down the hill.
