The Tappan RL-1 was wall mounted with the addition of a timer, 2 cooking speeds, and the ability to brown your food. It cost US $1,295, putting it out of the reach of most people.]]> 2021-11-02 21:44:27 UTC https://padlet.com/svasquez66/9v47ygnfeaf7sxpq/wish/1862884397 galtamirano4 https://padlet.com/svasquez66/9v47ygnfeaf7sxpq/wish/1862884461 In 1967 the first domestic microwave oven was introduced, it was called the Amana RadaRange and ran on 100 volts, costing just $495; much smaller, safer and more reliable than previous versions. This is an important milestone in the history of the microwave as it was the beginning (very slowly) of the use of microwaves in the home.]]> 2021-11-02 21:44:30 UTC https://padlet.com/svasquez66/9v47ygnfeaf7sxpq/wish/1862884461 galtamirano4 https://padlet.com/svasquez66/9v47ygnfeaf7sxpq/wish/1862892590 Because the water cooled system was not practical for a household microwave, Tappan engineers add an air-cooled system into the microwave.]]> 2021-11-02 21:50:30 UTC https://padlet.com/svasquez66/9v47ygnfeaf7sxpq/wish/1862892590 galtamirano4 https://padlet.com/svasquez66/9v47ygnfeaf7sxpq/wish/1862910369 A microwave oven is something that almost everyone has in their house and, basically, it is part of our lives. We depend on this spectacular electrical device to heat the food or make pop-corn. We think this invention makes our lifes easier and, probably, it is not going to change since now, we live in a technological era.
In conclusion, microwave world domination ;).]]> 2021-11-02 22:04:15 UTC https://padlet.com/svasquez66/9v47ygnfeaf7sxpq/wish/1862910369 xinca https://padlet.com/svasquez66/9v47ygnfeaf7sxpq/wish/1863515244 Little by little they managed to implant their invention not only in homes, but also in different industries such as wood drying. In the 70s was its great boom. In 1975 it overtook the gas cooker in terms of sales. Ten years later it was already in 60% of American homes.

Once considered a luxury, it has evolved, thanks to modern technology and popular demand, into a practical necessity for an active world.

In addition, you had to be very careful that the food did not overcook or even burn. In the 90s brands such as Panasonic and GE began offering models with a scrolling-text display showing cooking instructions.

A microwave oven heats food by passing microwave radiation through it. Microwaves are a form of non-ionizing electromagnetic radiation with a frequency higher than ordinary radio waves but lower than infrared light. Microwave ovens use frequencies in one of the ISM (industrial, scientific, medical) bands, which are reserved for this use, so they don't interfere with other vital radio services.]]> 2021-11-03 14:34:36 UTC https://padlet.com/svasquez66/9v47ygnfeaf7sxpq/wish/1864853266 svasquez66 https://padlet.com/svasquez66/9v47ygnfeaf7sxpq/wish/1864864437 Have you ever wondered what was it like when you couldn't heat your food on a microwave oven?
