Electric Scooter Taxis in Paris
If you find yourself in Paris and need a taxi to move around the city without luggage, think of City Bird's Electri-City service. City Bird itself is the first French motorcycle taxi service, and they have just added a couple of Vectrix electric scooters to their fleet.
Because of the limited range of the electric scooters, they can only be booked to go to locations inside of the city. Of course, you could always take the subway, o...

VW's 282 MPG Super Fuel Efficient Car
The 1-Liter car has been around in prototype form since 2002 and greens everywhere have been drooling at its 282 miles per gallon fuel economy (or 1 liter of gasoline per 100 kilometers, hence the name). VW has finally decided to make more and sell them, and a limited edition (estimated in the thousands) should start selling in 2010.
1-Liter Car Technical Specs
The One-Liter car (or 1-Litre, over in Europe) weights only 660 pounds. The body is made from carbon composites and it is shaped to be extremely slippery, giving it a coefficient of drag of only 0.16 ("the average car comes in around 0....

Wave Power Technology
Most wave power devices so far, like those from Ocean Power Delivery, are made of metal and contain many hydraulic rams, hinges and articulated joints. This makes them expensive, and the more things there are to break, the higher maintenance costs will be.
Introducing the Anaconda
Francis Farley, an experimental physicist, and Rod Rainey of Atkins Oil and Gas, have invented a new device that could help bring the cost of wave power down. They call it the 'Anaconda' after the species of aquatic boas (and a cheesy movie). It's bas...

In a complete turnabout the Food and Drug Administration has issued a health warning over amalgam dental fillings after insisting for years that they were safe. A change in stance which is a major victory for activists who claim fillings can cause a range of problems, including heart conditions and Alzheimer's disease.
According to their website, the FDA now states that fillings contain mercury that "may have neuro-toxic effects on the nervous systems of developing children and fetuses".

Bread & Butter, the trade show for selected brands, opened its summer doors again in Barcelona today for 3 days of clothing culture under the concept ‘New Order’. Apart from some of our favourite eco fashion labels we already met at Bread & Butter King Size in January, we really liked the ‘Collection of Hope’, resulting from a workshop by students of the ESMOD fashion schools. Africa and Social Responsibility inspired this project and lead to a discussion of textiles and clothing in modern Africa from dive...

Top Gear: Prius vs. BMW M3
We're pretty certain that the Top Gear people know more about cars than we do, so they really have no excuse for this segment on the Prius vs. BMW M3. It almost seems like they try very hard to be misleading and avoid explaining why their "test" has pretty much zero real-world value. But lets start at the beginning... First watch the video below, then read on....

Evisol makes "integrated solutions" for electric and hybrid vehicles (including boats). Drivetrains, batteries, that kind of stuff. How better to demonstrate their skills than by making an electric car of their own? Meet the Thorr electric roadster, a proud relative of the classic Lotus Super 7 concept.
Simplicity is the name of the game here. Low complexity, low weight. A car stripped of all the bells and whistles, except for the state of the art electric drivetrain. No ABS, power assisted braking, gearbox, power assisted steering, any form of sound absorption, not even a roof and a windshield (okay, that might be a bit overkill, but they'll probably tweak it some mo...

Stop-start technology makes a lot of sense, and we're quite disappointed that it is taking so long to become widespread. It conserves fuel and reduces emissions in city driving by shutting down the engine when the car is stopped (red light, dense traffic, etc), and restarting it instantaneously when the drive takes his or her foot off the brake pedal. You get part of the benefits of a hybrid car at a much lower price tag.
So it is not surprising that a new survey shows that 3/4 of UK drivers would buy a car with a stop-start system. Problem is, there are only three carmakers that offer stop-start systems on non-hybrid models, Citroën (we wrote about the

Forget about Formula 1, Nascar and monster trucks... Here comes chair racing!
Okay, we admit it's a bit silly. But we're pretty sure that it provides a lot more entertainment per kilojoule than anything else (anything that you do with clothes, anyway). It shows you don't h...

Spiegel Online published a series of pictures titled "Desertec: Strom aus der Wüste" (translation: Desertech: Electricity from the desert). It includes this image of how much land would be needed to power the world, Europe or Germany with solar-thermal power. The idea is similar to a post we did a year ago: How Much Land to Power The Whole World with Solar?
The red square on the left is for the whole world, in the middle for Europe-25, and on the right for Germany. Below you can see pictures of the kind of technology they're talking about. It's a bit similar to

The Motor Industry Research Association (MIRA), a British automotive design, development and certification consultancy, has done what many TreeHugger readers have been suggesting in the comments of many posts about plug-in hybrid cars: Removable battery packs that can be swapped.
Their test vehicle is a modified Skoda Fabia which they call the H4V (Hybrid 4 wheel drive Vehicle) because the gasoline engine powers the front wheels while two 35kW electric motors power the rear wheels. The regular gasoline version of the car gets 32 mpg (7.24 L/100km) while their 'plugless' plug-in hybrid prototype returned 53 mpg (4.4 L/100km)....

Volkswagen introduced a turbo-diesel hybrid-electric Golf concept car at the Geneva Motor Show, and the specs were impressive: 70 miles per gallon (3.3 liters per 100 kilometers), a 7-speed direct shift gearbox (DSG) with a twin-clutch, minor modifications to reduce aerodynamic drag, CO2 emissions of 89 g/km (lower than a Toyota Prius hybrid), and Tier 2 Bin 5 tailpipe emissions. And of course, the ability to run...

we mulled over the notion of whether colourful Crocs footwear might be the Birkenstocks for a new generation. Many respondents argued that without containing recycled content or at least a way of recycling the worn-out shoes they couldn’t be considered ‘green.’
Earlier this year Crocs seemed to have taken steps, if you will, to address these issues. Their new line of SolesUnited are made with grounded up old crocs. The new styles have 20% of this recycled content. Going one further Crocs plan, for 2008, to develop partnerships with shipping companies and worldwide non-profit organisations,...

Arguments against buying organic groceries almost always focus on price.
Now that home foreclosures and job losses are piling up, and people are tightening their belts across country, it's easy to imagine hordes of shoppers running from organics to supposedly cheaper "regular" food. (You've gotta love a world where the food that's been sprayed with toxic chemicals is normal and the other stuff gets its own tiny section of the supermarket.)
So here's today's good news: Organic is sometimes the cheaper option. We went comparison shopping and found that while it's still true that organic fruits and vegetables generally cost more than their pesticide-sprayed counterparts, there are many ex...

Bikie Introduces a Web Platform for New and Used Bicycles and Accessories in Germany
Well, this ad certainly gives a twist to bike rack scarcity, or finding the right new or used bike when you need one. The tag line at the end of the video translates roughly to "The right bike for every bum." ...
