A group of devices and machines for converting the mechanical energy of live loads into electricity. A generator is operated by gears which in their turn are operated by a Bourdon tube or similar-acting device fed by working fluid in a pipe from a reservoir. The reservoir walls are impacted by a choice of the rolling weight of a motor vehicle, the bending force on some object and/or by a decompressing force on the working fluid. The invention is applied to roadways, buildings, sailboats, cars with internal combustion engines, elevators, ships and bridges. If the varying impacts are caused by wind or subsurface ocean currents a new type of diverging nozzle is used to magnify pressure input. By using the invention pressure waves are used to transfer energy with minimal movement of working fluid, minimizing friction and other losses.
