The Trivection oven is a convection microwave created by General Electric, which combines radiant heat, convection, and microwaves for customized cooking. According to GE, it cooks food five times faster than a traditional oven. [1] Alton Brown, host of Good Eats, was involved in developing the oven. [2]
A microwave oven or simply microwave is an electric oven that heats and cooks food by exposing it to electromagnetic radiation in the microwave frequency range. [1] This induces polar molecules in the food to rotate and produce thermal energy in a process known as dielectric heating .
A microwave oven passes microwave radiation at a frequency near 2.45 GHz (12 cm) through food, causing dielectric heating primarily by absorption of the energy in water. Microwave ovens became common kitchen appliances in Western countries in the late 1970s, following the development of less expensive cavity magnetrons. Water in the liquid ...

A horn antenna serves the same function for electromagnetic waves that an acoustical horn does for sound waves in a musical instrument such as a trumpet. It provides a gradual transition structure to match the impedance of a tube to the impedance of free space, enabling the waves from the tube to radiate efficiently into space.
Examples include a home oven with a bowl of water and the pilot light on, a box with a bowl of hot water in it (the water is replaced periodically to maintain warmth), or a counter top proofer (an electric appliance) designed for home use. A dough retarder is a refrigerator used to control the fermentation of yeast when proofing dough. Lowering ...
8 January 1989 – In the Kegworth air disaster, a fan blade broke off in the left engine of a new Boeing 737-400, but the pilots mistakenly shut down the right engine. The left engine eventually failed completely and the crew were unable to restart the right engine before the aircraft crashed.
