Systems and apparatuses for delivering power and energy using deflecting beams or other oscillating members motivated to oscillate a beam assembly using an eccentrically balanced rotating body that induces deflections in the elastic beam or other oscillating member. One or more rotors may be used on the elastic beams and a mechanical output or outputs are connected to the elastic beams. The rotating body is advantageously maintained in rotation by pulses of electro-magnetic force. The oscillating beam or members are preferably driven at a natural resonant frequency to minimize losses and render more efficient the output which can be obtained. The pulse motor or motors can be powered using stored electrical energy, such as may be generated from solar panels, wind generators or other energy storage devices. One or more outputs may be used to drive heat pumps, compressors, pumps or other equipment to assist in independent energy systems.
