The burning of fossil fuels and plastic waste are devastating to the planet.  3D printing has the opportunity to move away from non-toxic, non-petroleum-based plastics from the get-go and 3Dom is on a mission to produce environmentally friendly filament.  Their latest is called “Wound Up” and, to put the third ‘r’ in “reduce, reuse, and recycle”, the material is made from recycled coffee grounds.

World’s thinnest lightbulb developed using graphene

worldsthinnest
A postdoctoral research scientist, Young Duck Kim,  has led a team of scientists from  Columbia, Seoul National University (SNU), and Korea Research Institute of Standards and Science (KRISS) that have demonstrated for the first time ever an on-chip visible light source using graphene, an atomically thin and perfectly crystalline form of carbon, as a filament.

Laser Makes Regular Lightbulbs Super-Efficient

Laser Makes Regular Lightbulbs Super-Efficient

Everything is Better with Lasers 

What if you could take a regular incandescent lightbulb, zap it with a powerful laser for a small fraction of a second, and make it about twice as efficient as a regular lightbulb? That seems to be what researchers at the University of Rochester did. What does the laser do? It creates an “array of nano- and micro-scale structures on the surface of [the] regular tungsten filament-the tiny wire inside a light bulb-and these structures make the tungsten become far more effective at radiating light.”
