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. One or more outputs may be used to drive heat pumps, compressors, pumps or other equipment to assist in independent energy systems.
