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 ...

Photonic crystals are nanoscopic structures designed to channel light of specific wavelengths while blocking other wavelengths. This ability to control and filter light with great efficiency makes ...

Lattices of microscopic tungsten rods can act as heat shields, researchers have found. Such structures may dramatically boost the efficiency of incandescent light bulbs and of thermophotovoltaic ...

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 ...

Over on YouTube [Drake] from the [styropyro] channel investigates what happens when you take an enormous tungsten incandescent light bulb and pump 30,000 watts through it. The answer: it burns bright ...

Cambridge University researchers have developed a $3 LED-based lightbulb that is 12 times more efficient than regular tungsten light bulbs, three times more than low energy ones. It lights up ...

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 ...

A microscopic 3-D tungsten photonic crystal lattice (TPCL) developed by Sandia National Laboratories (Albuquerque, NM) has demonstrated the potential to transmute the majority of wasted infrared ...

PHOENIX -- Saying they were striking a blow for individual rights, a Senate panel voted Tuesday to keep old-fashioned tungsten-filament light bulbs legal in Arizona long after they're banned by ...
