Stanford Engineers Invent High Tech Mirrors that Beam Light into Space

A new ultrathin multilayered material can cool buildings without air conditioning by radiating warmth from inside the buildings into space while also reflecting sunlight to reduce incoming heat.

Stanford engineers have invented a material designed to help cool buildings. The material reflects incoming sunlight, and it sends heat from inside the structure directly into space as infrared radiation (represented by reddish rays).
Stanford engineers have invented a revolutionary coating material that can help cool buildings, even on sunny days, by radiating heat away from the buildings and sending it directly into space.

Design flaw turns solar plant into a death trap for birds

bird

Super-concentrated sunbeams from BrightSource Energy Plant are deadly for birds flying overhead.

In February, the $2.2 billion BrightSource Energy Plant opened up in the Mojave Desert with good intentions: to harvest clean, sustainable solar power, by using 300 mirrors to reflect sunbeams onto a steam-producing water boiler. But a design flaw has turned the plant into a death trap for birds flying overhead.

The Japan Aerospace Exploration Agency plans to build an orbiting solar farm

mirrors

Mirrors in orbit would reflect sunlight onto huge solar panels.

What if you could imagine looking at Tokyo Bay from high above and seeing a man-made island in the harbor, 3 kilometers long. There is a massive net stretched over the island and studded with 5 billion tiny rectifying antennas, which convert microwave energy into DC electricity. Also on the island is a substation that sends that electricity coursing through a submarine cable to Tokyo, to help keep the factories of the Keihin industrial zone humming and the neon lights of Shibuya shining bright.

Scientists Directly Observe Three Distant Planets

Scientists Directly Observe Three Distant Planets 

 The Hubble Space Telescope captured a fuzzy image of the planet, known as Fomalhaut b, which is no more than a white speck in the dust ring that surrounds the star.

A little more of the universe has been pried out of the shadows. Two groups of astronomers have taken the first pictures of what they say – and other astronomers agree – are most likely planets going around other stars.

New Kind of Solar Dish to Energize Power Production

 New Kind of Solar Dish to Energize Power Production

Team leader Spencer Ahrens fastens mirrors in place using wire and plastic washers

Researchers say that a new type of solar energy collector, which concentrates the sun into a beam that could melt steel, could revolutionize global energy production. The prototype is a 12-foot-wide mirrored dish was made from a lightweight frame of thin, inexpensive aluminum tubing and strips of mirror. It concentrates sunlight by a factor of 1,000 to produce steam
