Telex starts as a way to distribute military messages, but soon becomes a world-wide network of both official and commercial text messaging that will persist in some countries into the s. Telex uses teleprinters, which date back to the s for use in telegraphy. But instead of using pricey dedicated telegraph lines, the telex system connects those teleprinters to each other over voice telephone lines, routed by modified telephone switches. Wireless versions of Telex soon connect remote regions of the developing world.
How does the microwave compare in energy use, say, to using a gas or electric stove burner to heat water for a cup of tea? Typically, though, a microwave would be slightly more efficient at heating water than the flame on a gas stove, and should use up a little less energy.
Given this logic, it is hard to believe that a burner element on an electric stovetop would be any better, but an analysis by Home Energy Magazine found otherwise. That said, the difference in energy saved by using one method over another is negligible: Choosing the most efficient process might save a heavy tea drinker a dollar or so a year.
Although a microwave may not save much energy or money over a stove burner when heating water, it can be much more energy-efficient than a traditional full-size oven when it comes to cooking food.
For starters, because their heat waves are concentrated on the food, microwaves cook and heat much faster than traditional ovens. For starters, make sure to keep the inside surfaces of your microwave oven clean so as to maximize the amount of energy reflected toward your food.
On a gas stovetop, make sure the flame is fully below the cookware; likewise, on an electric stovetop, make sure the pan or kettle completely covers the heating element to minimize wasted heat.
Also, use the appropriate size pan for the job at hand, as smaller pans are cheaper and more energy-efficient to heat up.
Despite these tips for cooking greener, Bluejay reiterates that most of us will hardly put a dent in our overall energy use just by choosing one appliance over another. Home Energy Magazine, www. BoxWestport, CT ; earthtalk emagazine.
