The IKAROS (Interplanetary Kite-craft Accelerated by Radiation Of the Sun) solar sail

Although the idea of a solar sail was first proposed some 100 years ago, to date none has been successfully used in space as a primary means of propulsion. The Japan Aerospace Exploration Agency (JAXA) is looking to change all that with its IKAROS project – not a misspelling of Icarus, rather an abbreviation of Interplanetary Kite-craft Accelerated by Radiation Of the Sun. Launched today aboard the H-IIA Launch Vehicle (H-IIA F17), IKAROS is a space yacht that gathers energy for propulsion from sunlight pressure (photons) by means of a square membrane measuring 20 meters (65.6 ft) diagonally.

MIT researchers have created a virus-templated catalyst solution used to harness energy fr...

A team of MIT researchers has managed to mimic the photosynthetic process in plants by engineering M13, a simple and harmless virus, to help splitting water into its two atomic components, hydrogen and oxygen, using sunlight. The researchers hope this is the first step toward using sunlight to create hydrogen reserves that could then be used to generate electricity or even produce liquid fuels for transportation.

A window frame and stirring branches projected by Adam Frank's REVEAL

Just the other day we brought you the story of SUNLIGHT, an art project featuring a giant solar-powered projection of the sun. It was designed and is being installed by Brooklyn artist Adam Frank. Upon looking over Mr Frank’s website we found an interesting little projector-type thingy-ma-jig that you can set up right in your own home. It’s called REVEAL, and it simulates the sun-cast shadows of a window frame and swaying tree branches on your inside walls. Just the thing for that dingy basement office. Read More

Adam Frank's SUNLIGHT at its peak, on the side of Denver's Minoru Yasui Building

As of July 1st, the city of Denver, Colorado will be lit by two suns. There will be the usual big one that shines throughout the day, but there will also be a smaller one that rises in the evening, climbs up the side of the Minoru Yasui office building throughout the night, then sets in the morning. That’s the plan, at least, for Brooklyn artist Adam Frank’s permanent installation entitled SUNLIGHT. Appropriately enough, the whole thing will be solar-powered. Read More

Dr Philip Rasch is Pacific Northwest National Laboratory's first Chief Scientist for Clima...

Scientists in the US have been cloud-spotting over shipping lanes and have noticed something more interesting than teddy-bear shapes and faces. They have detected that rising steam from passing ships has caused brightening in the clouds which they theorize alters the reflectivity of the cloud and prevents the energy from reaching the Earth. They propose that if this could be achieved artificially via geoengineering it could be an effective defense against global warming. Read More

Previous studies have indicated that painting the roofs of buildings white could be a low tech way to reduce global warming by reflecting the sun’s rays back into space. Now the first computer modeling study to simulate the impacts of white roofs on urban areas worldwide has added more weight to such a proposal indicating that painting every roof in a city entirely white could cool the world’s cities by an average of about 0.7 degrees Fahrenheit or 0.4 degrees Celsius.

Have you ever wanted to create your own little planet? Do you like aquatic life, but think that aquariums are too much work? If your answer to either of those two questions is Yes, then you might quite enjoy owning a miniature closed aquatic ecosystem. All you need is a credit card, or a clear glass jar, some stuff from a pond, and an appreciation for things that exist on a small scale. The result will be a self-sustained miniature world that doesn’t need feeding, filtration, or anything other than light, from the outside world. Read More

The GREENS solar panels can be rapidly deployed in the field to provide front line forces ...

In response to a Marine Corps requirement from Iraq for an expeditionary renewable power system, the Office of Naval Research (ONR) Advanced Power Generation Future Naval Capabilities program has introduced technology designed to harness some of the sunlight that beats down upon U.S. Marines operating in the Arabian Desert. Fueled by the sun, the Ground Renewable Expeditionary ENergy System (GREENS) is a portable, 300W, photovoltaic/battery system that provides continuous power to marines in the field. Read More

Zhong Lin Wang holds a prototype three-dimensional solar cell that could allow PV systems ...

The photovoltaic (PV) panels adorning the rooftops of buildings around the world have become a visible sign of the shift towards environmentally friendly solar power. Now researchers have developed a new type of three-dimensional PV system using optical fiber that promises solar generators that are foldable, concealed and mobile, meaning they could be hidden from view and leave rooftops panel-free.

The ReNu personal power generation and storage system

Solar power is being harnessed and applied in ever more interesting and creative ways, and the ReNu personal power generation and storage system is certainly no exception. The device features a freestanding modular solar panel that, once charged, can be slotted into a number of extensions to make use of the collected energy, including an iPod dock and an LED desk lamp.
