In Africa, for example, tourismâs effects on indigenous peoples have been profound, with the eviction of communities from their lands, in addition to economic dislocation, breakdown of traditional values, and environmental degradation.
The Invention of the Toaster. Who invented the toaster? George Schneider, who once worked for the American Electrical Heater Co. in Detroit, was the very first to apply for an electronic toaster patent application in the United States, which happened some time around 1893 to 1900.
A toaster works by applying radiant heat directly to a bread slice. When the bread's surface temperature reaches about 310 degrees Farenheit, a chemical change known as the Maillard reaction begins.Sugars and starches start to caramelize -- turn brown -- and to take on intense flavors. That's toast. 9 0 0 - 1 9 2 0. As stated above, toast is made by applying radiant heat to a slice of bread. This is easily done with fire, but creating an electrical device to toast bread presented quite a challenge.
