More than a century after their invention, tungsten filaments—the coiled metal wires at the heart of many incandescent light bulbs—continue to be popular. This is despite the growing market for LED ...

You probably know that an incandescent light bulb uses a tungsten filament. What's even cooler is that it's got 20 inches of double-coiled filament -- and tungsten is a brittle mineral that, under ...

Many credit the invention of the incandescent light bulb with Edison or Swan but its development actually took place over two centuries and by the time Edison and Swan got involved, the tech was down ...

Tungsten-filament bulbs — the most widely used light source in the world — burn hands if unscrewed while lit. The bulbs are infamous for generating more heat than light. Now a microscopic tungsten ...

LEWISTON — As the incandescent light bulb began to fade out of our lives in the early 2000s, the future for Philips Elmet was not so bright. Parent company Philips would phase out production of the ...

As inventors in the early 1900s vied to devise the best incandescent lightbulb, tungsten won out over carbon for making filaments. Today, however, there’s a form of carbon that was unknown back ...

With most of the apparatus and instruments we now take for granted yet to be developed, the early pioneers of the Electric Age had to bring a lot to the lab besides electrical skills. Machining, ...

Researchers create a prototype bulb with a carbon nanotube in place of the standard tungsten filament. It uses less power, burns brighter and could lead to the first major overhaul in bulb design in a ...

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 ...

The warm glow of an old electric light-bulb, which has been banned in many countries because it is so energy inefficient, may soon be making a comeback following a breakthrough in “light recycling”.

Add Yahoo as a preferred source to see more of our stories on Google. Imagine a light bulb that has been burning since 1901. Nestled in a quiet Californian fire station, the Centennial Light ...
