A halogen oven, halogen convection oven, or halogen cooking pot is a type of oven that utilizes a halogen lamp as its heating element. Halogen ovens are often noted for being more energy-efficient than a conventional electric oven due to their more effective heating of food and faster cooking times.
Ahearn and Warren Y. Soper were owners of Ottawa's Chaudiere Electric Light and Power Company. [4] The electric stove was showcased at the Chicago World's Fair in 1893, where an electrified model kitchen was shown. Unlike the gas stove, the electrical stove was slow to catch on, partly due to the unfamiliar technology, and the need for cities ...
Induction cooking allows high power and very rapid increases in temperature to be achieved: changes in heat settings are instantaneous. [ 1 ] Cooking vessels with suitable bases are placed on an induction electric stove (also "induction hob" or "induction cooktop") which generally has a heat-proof glass-ceramic surface above a coil of copper ...
A halogen lamp (also called tungsten halogen, quartz-halogen, and quartz iodine lamp) is an incandescent lamp consisting of a tungsten filament sealed in a compact transparent envelope that is filled with a mixture of an inert gas and a small amount of a halogen, such as iodine or bromine.
This is the ratio between the total luminous flux emitted by a device and the total amount of input power (electrical, etc.) it consumes. The luminous efficacy of the source is a measure of the efficiency of the device with the output adjusted to account for the spectral response curve (the luminosity function).
Efficiency of power plants, world total, 2008. Energy conversion efficiency (η) is the ratio between the useful output of an energy conversion machine and the input, in energy terms. The input, as well as the useful output may be chemical, electric power, mechanical work, light (radiation), or heat. The resulting value, η (eta), ranges ...
The most serious charge against the man accused of killing the UnitedHealthcare CEO in broad daylight last week on a Manhattan sidewalk is murder in the second degree. Given the image of the ...
In 1999, the US Department of Energy projected that office equipment would be the fastest-growing commercial end use between 1998 and 2020. [5] The Commercial Buildings Energy Consumption Survey (CBECS), a national sample survey project of the US Energy Information Administration, reported that based on 2003 data, 19% of the total energy of US office buildings is attributed to plug load energy ...
