New Thermoelectronic Generator Converts Heat And Solar Energy Into Electricity
2013-12-03 16:09:29

American Institute of Physics Through a process known as thermionic conversion, heat energy -- such as light from the sun or heat from burned fossil fuels -- can be converted into electricity with very high efficiency. Because of its promise, researchers have been trying for more than half a century to develop a practical thermionic generator, with little luck. That luck may soon change, thanks to a new design -- dubbed a thermoelectronic generator -- described in AIP Publishing's Journal...

Lee De Forest invented the Audion, a forerunner of the triode, which is an amplifying vacuum tube. The grid controls the filament which sends the current from the filament. The Audion can detect radio signals by applying a small amount of power to the grid that can control a larger current from the filament plate. However, De Forest's Audion is distinct from the true vacuum triode since it is not capable of linear amplification. De Forest found that when gas was in a partial vacuum heated...

The Cathode Ray Tube, which has internal or external means to accelerate and deflect electron beams, is a vacuum tube containing an electron gun and a fluorescent screen. The electron beams that are deflected are used to create images in the form of light emitted from the fluorescent screen. The CRT works by using an evacuated glass envelope which is large, deep, heavy, and relatively fragile. Ferdinand Braun is credited with the first CRT in 1897. It can also be known as the Braun tube....
