A baked potato in six minutes flat...piping-hot biscuits in about 20 seconds...a sirloin steak (rare) in five minutes--these days my wife can cook elaborate dinners, made with fresh food, in less time than it takes to read the directions on a TV dinner. Her secret is our new microwave oven, made by International Crystal Mfg. Co., 10 N Lee St., Oklahoma City.
The "oven" is really a stainless-steel-surrounded cavity (the cooking chamber) hooked up to a miniature radar set. Radar waves (at microwave frequencies) piped into the cavity penetrate the food and heat it internally.
Because there's no conventional heat source inside, my wife cooks on paper plates (they don't absorb microwaves, so they stay cool) making clean-up easy. The tablet-top unit costs $575. [Note: In 2012 money, that microwave cost just north of $3,800 (!).]
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
