Revolutionary tungsten photonic crystal could provide more power for electrical devices
You can‘t get something for nothing, physicists say, but sometimes a radical innovation can come close.
Researchers at Sandia National Laboratories — exceeding the predictions of a 100-year-old law of physics — have shown that filaments fabricated of tungsten lattices emit remarkably more energy than solid tungsten filaments in certain bands of near-infrared wavelengths when heated.
This greater useful output offers the possibility of a superior energy source to supercharge hybrid electric cars, electric equipment on boats, and industrial waste-heat-driven electrical generators. The lattices’ energy emissions put more energy into wavelengths used by photovoltaic cells that change light into electricity to run engines.
John McCarthy's Sustainability page
Humanity has progressed over hundreds of thousands of years, but until about the seventeenth century, progress was a rare event. There were novelties but a person would not expect a whole sequence of improvements in his lifetime. Since then scientific progress has been continual, and in the advanced parts of the world, there has also been continued technological progress. Therefore, people no longer expect the world to remain the same as it is. [Very likely, the greatest rate of progress for the average person occurred around the end of the 19th century when safe water supplies, telephones, automobiles, electric lighting, and home refrigeration came in short order.]
