Plan to turn rooftops, walls and windows into cheap solar cells

By Jeff Salton

19:23 August 25, 2009 PDT

Chemical engineering Professor Brian Korgel tests one of his printed solar cells

Cheaper solar cells – roughly one-tenth the cost of current day prices – could be available within three to five years thanks to a manufacturing procedure that uses nanoparticle ‘inks’ to print them like newspaper or to spray-paint them onto the sides of buildings or rooftops. Even windows could become solar cells thanks to the semi-transparent inks. 'Painting' solar cells on buildings has been an idea in the making for some time – Gizmag investigated the possibilities of 'solar paint' in 2008. Read More

The ALICE-powered NASA rocket launched in Indiana this month

NASA and the Air Force Office of Scientific Research (AFOSR) have successfully launched a nine-foot rocket to a height of 1,300ft using an environmentally-friendly propellant made from aluminum powder and water ice. The fuel, called ALICE, has the consistency of toothpaste with a high burn rate and achieved a maximum thrust of 650 pounds during this test. Read More

While it’s true that water and oil don’t mix, water may soon be all a person needs to completely remove any trace of an oil spill - provided the surfaces are coated with newly designed polymer materials that would do away with harsh chemical detergents and solvents. And if you have ever been inconvenienced by fog on your bathroom window, car windshield, or eyeglasses, the same materials can be used as an anti-fog agent with similar eco-friendly benefits.

Desalination plants generally employ one of two methods to produce clean water – reverse osmosis or electrodialysis. Unfortunately, both processes require large amounts of energy, but an international team of researchers has proven a process that cleans wastewater can also remove 90 percent of salt from brackish water or seawater while generating electricity.

The bamboo frame is strong, good looking and may even give a smoother ride

Undoubtedly a pretty environment-friendly way to travel, donning a pair of skates still leaves you with a bit of an eco-headache. With all that plastic and metal wrapped around your ankles, the skates themselves are a bit of an environmental let down - until now. Inline skate innovators at K2 skates have recently added another industry first to the company's catalogue of cutting edge developments. Not only are the boots and laces made from recycled plastic bottles but the wheel frame is made from one of the most sustainable materials on the planet, bamboo. Read More

Scientists at SRI International have found an innovative design for organic light-emitting diodes (OLED) that makes use of cavities to enhance their luminosity and energy efficiency. The device, called a COLED (where the 'c' stands for 'cavity') was designed by Dr. Yijian Shi and employs a regular pattern of cavities, implementing a structure that generates as much as five times the light output of a standard OLED per watt consumed depending on the color being displayed.

Gizcast #9: can Vertical Farming solve the impending global food crisis?

In this week's Gizcast, we're privileged to be joined by Dr. Dickson Despommier of New York City, who is perhaps the world's leading expert on Vertical Farming, a topic we've covered several times in the past few years. Dr. Despommier speaks with Loz Blain about the social, economic and environmental issues we'll have to face as the Earth's population jumps to 9 billion in the next 40-50 years. If we keep farming the way we are now, we're simply going to run out of land to feed ourselves - so the solution seems clear: we need to start bringing food production and agriculture into the high-rise age. The farms of the future, it seems, will be skyscrapers. Geoffrey Baird also joins us for a weekly roundup of top stories. Read More

Canadian startup proposes nuclear fusion power plant at a bargain price

By Darren Quick

00:40 August 4, 2009 PDT

A picture from the patent filing for General Fusion’s proposed fusion reactor.

Nuclear fusion offers a completely clean method of producing vast amounts of energy. So far the major stumbling block for scientists has been creating a controllable fusion reaction that achieves “net gain”, meaning it gives off more energy than is needed to trigger it. But Canadian startup, General Fusion, is claiming it can build a relatively low-tech prototype nuclear fusion power plant within the next decade for less than a billion dollars. Read More

Vertical Landscapes: The only way is up for green cities

By Darren Quick

Artists impression of a VES in New York

Demand for office and housing space in ever diminishing land space has led to taller and taller buildings reaching for the skies in cities around the world. This shortage of land in many cities has unfortunately also led to a scarcity of natural vegetation in urban settings. We’ve looked at several vertical-farming concepts - dedicated buildings that provide space to grow crops in city centers - but a new architectural system from Vertical Landscapes (VL) seeks to invite nature back into our cities on a broader scale. The architectural system transforms buildings into columns of vegetation to add a much needed touch of green, help clean the city air and possibly even produce small scale crops, all while retaining the building’s usual use for office or housing space.

Geothermal power is cost effective, reliable, and environmentally friendly, but it has previously been limited to geographic areas near tectonic plate boundaries. New technologies, such as that employed in the Raser low-temperature binary geothermal plant, promise to expand the opportunities for geothermal plants.

There’s nothing like the smell of freshly-cut grass to bring back fond childhood memories of summer…alongside less fond memories of the sickly, sweet smell of mower fuel and the sound of cursing all over the neighborhood as people failed to get their lawn mower started. It’s no wonder that electric mowers have become so popular in recent times given they are easy to operate, quiet, require little maintenance and don’t strain your back (or your good mood) trying to start them. They are also much better for the environment than their fuel-guzzling two-stroke engine ancestors. The Recharge Mower offers all these benefits - and you don't have to push it. Read More
