Wind Powered car sets new world record at 126mph

By - March 29, 2009 6 Pictures
With a wind speed of just 30mph (48kmh), British engineer Richard Jenkins has set a new land speed record for a wind-powered vehicle at blistering 126.1mph. Driving the Ecotricity sponsored all carbon fiber land yacht Greenbird across the Ivanpah dry lake bed on the Nevada / California border Jenkins eclipsed the previous benchmark set a decade ago by American Bob Schumacher by almost 10 mph. It also continued a the rivalry between Britain and the United States for setting speed records that dates to the 1920s, when Sir Malcolm Campbell set several records on land and sea. Read More

Lithium Ion Battery breakthrough promises 100-fold boost in performance

By - March 16, 2009 2 Pictures
Researchers have developed a new advanced Lithium Ion battery that will allow mobile phone and laptop computers to be fully charged in seconds. Electric car batteries may be charged in as little as five minutes, removing one of the main barriers to wider uptake of EVs. Solar and wind power generation could also benefit as better batteries could be used to store surplus energy. Read More

Spain sets new wind power record supplying 40% of total demand

By - March 12, 2009 1 Picture
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

Magenn floating wind generators take advantage of high altitude winds

By - February 26, 2009 9 Pictures
Wind power is notoriously flighty, particularly at ground level. Most turbine-on-a-post wind powered generators operate at around 20-40% of their rated generation capacity, simply because wind is intermittent and changes direction. But a generator situated 500-1000 feet above ground level would enjoy much more consistent strong wind - which is why the Magenn MARS system makes so much sense. It's a helium-filled rotating airship that spins in the wind on the end of a variable-length tether that also acts as a power transmitter, and it's expected to operate at more like 50% of its rated capacity. Each MARS system will be cheap and portable, which will make them extremely useful in rural, camping and emergency situations. A prototype has successfully been flown in North Carolina. A great idea that makes economic sense. Read More

Febot uses wind power to recharge batteries

By - February 23, 2009 2 Pictures
We're always on the lookout for new, ‘greener’ ways of saving or renewing energy. South Korean designers Ji-yun Kim, Soon-young Yang and Hwan-ju Jeon have developed the Febot, a small, easily-assembled portable battery charger concept that harnesses the power of the wind rather than using electricity. Place a rechargeable battery inside the Febot and stick it on the outside of a window or wall, or any other outdoor surface, using the suction cap at the base of the unit. Read More

Wave and wind power hybrid for off shore wind farms

By - February 9, 2009 3 Pictures
Bringing together the benefits of two eco-friendly forms of power generation, Scottish company Green Ocean Energy has developed a wave power machine that attaches to an offshore wind turbine. The system, known as the Wave Treader, comprises two 20 m (66ft) long floats molded from GRP (Glass Reinforced Plastic) at ocean level attached to a wind turbine tower by 50 m (165 ft) long pivoting beams. As the floats move up and down in response to constant wave action, the arms move hydraulic cylinders attached to the beams by levers, which in turn spins a hydraulic motor connected directly to an electric generator.

Windspire: low cost, small footprint wind power alternative

By - January 29, 2009 2 Pictures
While wind turbines are a clean, green way to generate power, they can be a bit of an eyesore and require quite a bit of room meaning, more often than not, they need to be located in sparsely populated areas far from where the generated power is actually needed. We’ve looked at AeroVironment’s innovative urban solution as well as StatoilHydro’s HyWind. Now a look at another innovative product - Windspire. The Windspire, from Reno, Nevada based Mariah Power, combats the large footprint problem by employing a propeller-free design that makes it ideal for rural, suburban, and even some urban residential environments.

French skyscaper puts focus on renewable energy

By - October 19, 2008 3 Pictures
Extensive use of solar and wind power plus a healthy dose of CO2 munching foliage will mark the slim, 318 meter tall Generali Tower when it becomes a fixture of the Parisian skyline from 2012. The design from Valode & Pistre was selected in an international competition and will form a key plank in the nine year plan to revamp the La Défense business district first announced by the Public Body for the development of La Défense (EPAD) in 2005.
