Micropower describes the use of very small electric generators and prime movers or devices to convert heat or motion to electricity, for use close to the generator. The generator is typically integrated with microelectronic devices and produces "several watts of power or less." These devices offer the promise of a. .
The components of any engine — the , the , and the rotor — are fabricated from etched , much like . The technology holds the promise of ten. .

Professor Orest Symko of the physics department and his students developed Thermal Acoustic Piezo Energy Conversion (TAPEC), devices of a cubic inch (16 cubic centimeters), or so, which convert waste heat into acoustic resonance and. .

[pdf] A dwarf planet is a small that is in direct orbit around the , enough to be , but insufficient to achieve like the eight classical of the . The prototypical dwarf planet is , which for decades was regarded as a planet before the "dwarf" concept was adopted in 2006.
[pdf] A plentiful head of water can be made to generate directly without moving parts. In these designs, a falling column of water is deliberately mixed with air bubbles generated through turbulence or a pressure reducer at the high-level intake. This allows it to fall down a shaft into a subterranean, high-roofed chamber where the now-compressed air separates.
