An experimental model, developed by General Electric, weighed just 10 ounces and was capable of working without light and recharging. It contained seven solar cells, four transistors and a small battery. [2] [3] In 1954, Western Electric began to sell commercial licenses solar powered radio, including other photovoltaic technologies. [4]
The solar dynamo is a physical process that generates the Sun's magnetic field.It is explained with a variant of the dynamo theory.A naturally occurring electric generator in the Sun's interior produces electric currents and a magnetic field, following the laws of Ampère, Faraday and Ohm, as well as the laws of fluid dynamics, which together form the laws of magnetohydrodynamics.
A dyno torch, dynamo torch, or squeeze flashlight is a flashlight or pocket torch which generates energy via a flywheel. The user repeatedly squeezes a handle to spin a flywheel inside the flashlight, attached to a small generator/dynamo, supplying electric current to an incandescent bulb or light-emitting diode. The flashlight must be pumped ...

Lifeline Energy (formerly Freeplay Foundation) is a non-profit social enterprise that provides technology solutions [buzzword] for off-grid learning. The organization designs, manufactures and distributes solar and wind-up media players and radios for classroom and group listening and was behind the first solar and wind-up radio for humanitarian use which launched in 2003.
A batteryless radio is a type of radio receiver that does not require the use of a battery to provide it with electrical power. Originally this referred to units which could be used directly by AC mains supply (mains radio); it can also refer to units which do not require a power source at all, except for the power that they receive from an ...
Energy harvesting (EH) – also known as power harvesting, energy scavenging, or ambient power – is the process by which energy is derived from external sources (e.g., solar power, thermal energy, wind energy, salinity gradients, and kinetic energy, also known as ambient energy), then stored for use by small, wireless autonomous devices, like those used in wearable electronics, condition ...
Wireless light switches eliminate the wire from the light to the switch location. This is useful in remodelling situations where new wiring can be a hassle. Rather than tearing down a wall to gain access to the wires, a wireless switch can be used. This avoids any need to access wires and makes remodelling fast and simple.
