Geräuschlos durchs Gehölz
Dank rapider Fortschritte der Batterietechnik taugen Elektrofahrzeuge nun auch für den Sport. Erste strombetriebene Motocross-Motorräder sind bereits im Handel.
Artig sieht es nicht aus, das Gefährt namens Quantya. Man assoziiert diesen Zweiradtyp mit furchtlosen Hünen, die im Hartplastik-Harnisch durch die Krume pflügen, als gäb's keinen Naturschutz - und dann dieses kehlige Geknatter: RrrrräääängtängtätätÄÄÄNG. Die gesellschaftliche Akzeptanz von Motocross scheint im Kanon modernen Freizeitsports kaum unterbietbar.

Solar plant yields water and crops from the desert
Vast greenhouses that use sea water for crop cultivation could be combined with solar power plants to provide food, fresh water and clean energy in deserts, under an ambitious proposal from a team of architects and engineers.
The Sahara Forest Project, which is already running demonstration plants in Tenerife, Oman and the United Arab Emirates, envisages huge greenhouses with concentrated solar power (CSP), a technology that uses mirrors to focus the sun's rays, creating steam to drive turbines to generate electricity.

Billionaire oilman backs wind power
CNN is reporting that oil billionaire T. Boone Pickens is planning to invest billions of dollars in what will probably be the world's largest wind farm. It will eventually generate 4 gigawatts, enough to power 1.3 million homes. The first 600 GE wind turbines are scheduled for delivery in 2010. Pickens says that each turbine will generate about $20,000 in income annually for the landowner who hosts it

Hydrogen Cars Won't Make a Difference for 40 Years
President Bush, Gov. Arnold Schwarzenegger and the big automakers agree on this much: They love hydrogen-powered fuel cell technology and its promise of a zero-emission, petroleum-free future.
Unfortunately, experts say it will be 40 years or more before hydrogen has any meaningful impact on gasoline consumption or global warming, and we can't afford to wait that long. In the meantime, fuel cells are diverting resources from more immediate solutions.

Magenn Power Floats Balloon Wind Turbine
While interest in solar power is picking up, another technology is also gaining a lot of attention. The chief problems with wind power are consistency and strength of the winds. Some areas simply do not get strong winds regularly and even areas that do can go days without experiencing strong winds. One solution is to build turbines at higher altitudes land areas.

Will California Kill the Electric Car — Again?
EV advocates say the California Air Resources Board is trying to kill the electric car -- again.
Under a proposal pending before the Air Resources Board, state regulators would slash -- from 75,000 to as few as 27,500 -- the number of zero-emission vehicles automakers must build between 2012 and 2017. Under the changes, the big automakers could put fewer than 2,500 nonpolluting cars on the road in the next four years. That's only 300 more than Tesla Motors plans to produce in the next two.

Paint on Solar Power!
Installing solar panels on the roof of every new building in the world would go a long way towards solving our energy needs, but as we all know, solar panels are costly and often difficult to install. But what if the solar panel was an integral part of every building? What if solar cells could be painted on building products? Well, according to a team from Swansea University this type of technology will soon be coming to a hardware store near you.

1 Gallon of Gas, 100 Miles — $10 Million: The Race to Build the Supergreen Car
Standing on the roof of a boxy old Buick, Kevin Smith has a great view of the vast boneyard at Kertow Auto Salvage, outside Taylorville, Illinois. He's here looking for the key to America's super-fuel-efficient future. "Found it," he says to me, spying a cluster of mid- to late-'90s Dodge Neons in the middle distance. He stomps down off the trunk and, followed by three buddies, converges on 11 promising carcasses. They pick through gaping engine compartments and weedy wheel wells, searching for an intact manual transmission — its rudimentary design should be easy to fit to Smith's custom-fabricated hybrid engine. "The geometry has already been engineered," he says. "There's no need to reinvent the wheel."

Eco-Boat Powered Attempts Round the World Speed Record
The 24 metre Earthrace, skippered by New Zealander Pete Bethune, will set off from Valencia, Spain, on March 1 and traverse the Atlantic, Pacific and Indian oceans as well as the Panama and Suez canals in its more than 24,000-nautical-mile journey.

New Light Glows For 12 Years
Litroenergy is a new type of material that emits light for 12 years without needing electricity or sun exposure. The self-luminous micro-particles are called Litrospheres and are said to be non-toxic and inexpensive. The light is said to be equivalent to a 20 watt incandescent bulb (lumens please?).

The future is bright for LEDs
New generation Light Emitting Diodes will purify water, make lights that mimic the colour of sunshine, and keep private data immune from hackers.
Dr Rachel Oliver, an LED researcher from the University of Cambridge, thinks that they could easily succeed tungsten bulbs as the main way to light our homes.
