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. [1] The generator is typically integrated with microelectronic devices and produces "several watts of power or less."
A microturbine (MT) is a small gas turbine with similar cycles and components to a heavy gas turbine. The MT power-to-weight ratio is better than a heavy gas turbine because the reduction of turbine diameters causes an increase in shaft rotational speed.
Small wind turbines often have passive yaw systems as opposed to active ones. They use a direct drive generator and use a tail fin to point into the wind, whereas larger turbines have geared powertrains that are actively pointed into the wind. They usually produce between 500 W and 10 kW, with some as small as 50 W.
Microgeneration is the small-scale production of heat or electric power from a "low carbon source," as an alternative or supplement to traditional centralized grid-connected power. Microgeneration technologies include small-scale wind turbines , micro hydro , solar PV systems , microbial fuel cells , ground source heat pumps , and micro ...
Small scale thermoelectric generators are also in the early stages of investigation in wearable technologies to reduce or replace charging and boost charge duration. Recent studies focused on the novel development of a flexible inorganic thermoelectric, silver selenide, on a nylon substrate.
It's always a good idea to have a backup power source on hand, but the Grecell Portable Power Station is useful for more than just safety. It's also a great camping companion! You can bring some ...
