First glimpse of solar-powered plane draws big crowd
03:41 July 3, 2009 PDT
After six long years of planning, talking and hard work, the world has finally had its first look at the 100% solar-powered Solar Impulse HB-SIA. This remarkable feat of engineering, with the wingspan of a Boeing 747 but only the weight of an average family car, has over 12,000 solar cells powering four electric motors with a maximum power of 10HP. The aircraft prototype is expected to take its first flights before the end of the year. Read More

Green energy charger ready and pumped for UK's biggest music festival
By Paul Best
23:30 May 26, 2009 PDT
Mobile operator Orange and renewable energy specialists GotWind know they’ve hit on a good, marketable idea. The companies have joined forces for a third consecutive year to showcase their outdoor charging solution at next month's Glastonbury Festival, the United Kingdom’s largest and hippest open-air music bash. This year Orange has unveiled a mobile phone charger prototype it’s calling the Orange Power Pump. By treading on what is essentially a standard camping air foot-pump, the kinetic energy created drives a small turbine inside the Power Pump. The energy is converted into electrical current, which recharges the mobile phone. The idea is not only simple, it cleverly encourages you to dance and charge your mobile at the same time. Read More

Air-fueled battery boosts capacity tenfold
By Darren Quick
22:52 May 20, 2009 PDT
Rechargeable lithium-ion batteries are the preferred power storage technology for the vast majority of portable devices, such as cell phones, laptop computers and MP3 players. They have also made their way into electric cars, but even with recent developments making them more effective, storage capacity continues to remain a problem. Now researchers at the University of St Andrews, with associates at Strathclyde and Newcastle, have developed a new type of air-fueled battery that could provide up to 10 times the energy storage of existing designs, paving the way for a new generation of electric cars and portable devices.

Raser low-temperature binary geothermal plant goes online
By Paul Evans
21:19 May 5, 2009 PDT
Raser Technologies has begun delivering 10 megawatts (MW) of clean, renewable electricity to Anaheim, California, from its first low-temperature, binary geothermal plant, the Hatch Geothermal Power Plant in Beaver County, Utah. Traditionally, the lead time on a geothermal plant is three to five years, but the USD$33-million Raser plant has been powered up just five months after ground-breaking. To help meet such rapid construction schedules, the plant uses off-the-shelf modular components, taken from the air conditioning industry, which are essentially running in reverse. Read More
Pixel building aims to be world's first carbon neutral office development
By Paul Best
23:57 May 3, 2009 PDT
Australian developer Grocon plans to build the country’s first carbon neutral office building on a former brewery site in the city of Melbourne – and possibly the first of its kind in the world. According to the developer, the $6 million, four-storey building has been designed to generate more energy on the site than it uses, offsetting the carbon emissions produced to operate it – and, in time, the greenhouse gases generated in making and installing the construction materials.

Spain sets new wind power record supplying 40% of total demand
By Paul Evans
01:30 March 12, 2009 PDT
Wind Turbines in the north west of Spain set a new record for power generation on March 5th as gales blew across the country, with more than 40% of the country's energy needs being generated by wind turbines. The new record stands at a peak of 11,180 megawatts (11.18 GW) of electricity supply beating the previous record of 10,032 megawatts. The percentage of demand supplied depends on time of day as demand rises and falls throughout the day. Read More

Unique hydro energy system harnesses slow water currents
22:21 November 24, 2008 PST
Hydro-power systems are by far the most widely used form of renewable energy on the planet, but despite their eco-friendly appeal the implementation of large scale facilities - particularly where dam building is involved - has some serious environmental and economic drawbacks. One solution to this impasse that is growing in support is to use leaner, less destructive systems to better harness current flow and provide energy at a local level. This is the thinking behind VIVACE, a machine developed at the University of Michigan which applies the same principles fish use to swim efficiently in order to generate power from currents much slower than those required to drive designs based on turbines and water mills.
