(1) Gravity assisted mechanical machine that uses a combination of stored mechanical energy plus the downward force of gravity, regulated by a motor and a sophisticated switch powered by a rechargeable battery. The mechanical switch is also assisted by a lever so the motor is more efficient in the use of the battery power. (2) Older types of fuel powered mechanical machines cause greater pollution and need an enormous amount of support to continue operating daily. (3) The gravity assisted mechanical machine can be used without air and operates longer and more efficiently and is less noisy and has no emissions to cause pollution. It will not heat up like a conventional mechanical machine only when attached to a generator for electrical energy. It will work without the need for the enormous weight of fuel to produce electrical energy. It can be used to power some electrical generators, example wind mill generators, for all uses of electrical energy.
