New system powerlessly switches windows from transparent to opaque

August 16, 2016

It wasn’t long ago we told you about the recent Harvard University researchers who created windows that transformed from transparent to opaque with just the flick of a switch, but now a team from MIT has taken that idea one step further. The researchers developed a new way of making windows switch from transparent to opaque — with no power. The new technology could potentially save energy by blocking sunlight on…

As many people who live in impoverished regions around the world start shifting away from fuel-based lighting, like candles, firewood, and kerosene lanterns, to solar-LED systems, this trend comes with more than just environmental benefits. A new study by Lawrence Berkeley National Laboratory (Berkeley Lab) found that it also sparks economic development as well, with the potential to create 2 million new jobs. Evan Mills, the Berkeley Lab researcher who has been…

Video of the Day: What an illuminated 20,000-Watt light bulb looks like

July 19, 2016

A YouTuber and electrical engineer by the name Photonicinduction has given tech enthusiasts a treat in his latest video. Photonicinduction manages to light up a 20,000-Watt light bulb — a bulb that could cost nearly $3,000. The hobbyist plugs his light bulb into a machine that can control the current and when he lets it all go, it looks almost like a fire. To give you an idea of how powerful a 20,000-Watt…

Light pollution is causing city moths to run in order to survive

April 13, 2016

Ever here the classic phrase “like a moth to a flame,” which alludes the well-known attraction moths have to bright lights? It may not be so anymore, thanks to a global increase in light pollution. City streets are flooded with artificial light-sources like lamp posts, street lights, and business signs, and its having a negative effect on organisms and entire ecosystems. The consequences of this light influx are particularly hard on nocturnal insects,…

Windows go from transparent to opaque with the flick of a switch

March 16, 2016

Instead of drawing your blinds to get some privacy, what if you could just flick a switch and even adjust how much light you let in? Not impossible thanks to a technique developed by researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences. The new technique can quickly change transform a window into a cloudy or clear surface — or somewhere in between — using geometry to adjust the…
