actually putting less energy and obtaining more energy is quite impossible ...because
(1)- most of the energy put into a machine gets lost or wasted due to surface and air friction ... (even in, space though there is no air friction, surface friction between 2 objects is always present)
(2)-suppose such a method can be used, if you just theoretically cancel out the energy put(which is less) and the energy obtained(which is more), then it is kind of obtaining free energy..which is not possible.
you can you use other forms of energy like solar energy which is obtained free(literally) to run such machines.
