Cutting down on unnecessary electricity usage has clear benefits for both the environment and your hip pocket, and devices that tackle the issue of standby power are an obvious place to start. Paul Lester takes a closer look at some of the current solutions on the market. 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.

A group of French students are getting ready to fly across the English Channel in the world's first solar powered airship. One hundred years after Louis Blériot won the coveted Daily Mail prize of £1000 by being the first to traverse the watery expanse in his 3-cylinder, 25 horse-power XI monoplane, the Projet Sol'r team will take to the skies in Néphélios, a 22 meter long airship capable of cruising at 30-35kph. Gizmag recently talked to one of the project's founders, Arnaud Vaillant. Read More

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

Trucks of the future could be equipped with an on-board digital co-driver to help the human behind the wheel, or even take over if the driver loses control. The HAVEit project (short for Highly Automated Vehicles for Intelligent Transport) has 28 million euros (USD$40 million) at its disposal and is aiming to develop an intelligent driver assist system that responds to both traffic conditions and drivers' needs.

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

Gizmag is always on the lookout for alternative means of powering vehicles and saving precious fossil fuels. But, in truth, the vast majority of us still drive exclusively petrol-powered cars. And the even sadder truth, outlined in a new research from the University of Michigan, is that the average fuel efficiency of a US vehicle has improved only three miles per gallon since the days of the Ford Model T.

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.

Scientists in Nevada have found a new and environmentally friendly source of biodiesel – “chicken feather meal”, a delightful material that consists of chicken feathers, blood, and innards made from the 11 billion pounds of poultry industry waste that accumulates annually in the US alone. Read More
