The normal propeller wind turbines are sometimes quite dangerous to birds because of the huge sweep area of the blades and when there is wind, the propellers move fast which birds sometimes cannot see. Vertical axis wind turbine, like this one in the video, are cool. This vertical wind turbine from mariah power has 1.2Kw
We have another big solar projest. This time the realisation si gonna be in Australia. This time it is the company WorleyParsons, who strangely is inthe coal, nuclear and Canadian oil sands bussiness.Strange? Maybe not. Maybe they just feel that the time for coal are finished? That the future is the renewable energy? Yes. I
New company – Biosolar- has made the backsheet for solar panels not from plastic but from cotton and castor beans. We all knows that the plastic is mostly made from petroleum based products. Using the alternate products for the fabrication process instead of the classic plastic cuts the costs about 25%. “It’s renewable and you
I found this arbicle about the USB key made out of corn….. Enjoy.. This is latest drive from Hong Kong-based. Hoshino also takes a decidedly different approach than other drives that simply keep the hazardous chemicals and whatnot to a minimum, with it actually constructed out of polylactide (or PLA) made from corn that is,
There is a company selling products which will standardise plugs and save power we all using in our gadgets. Green Plug is an embeddable, universal, energy-efficient power technology for DC-powered devices including cell phones, PDAs, laptops, printers, digital cameras, camcorders, cordless drills, MP3 players and dozens of common devices that today require individual, custom AC
The i MiEV is powered by a 330-volt lithium ion battery system mated to 47kW electric motor that provides better performance than the standard 64-hp gasoline engine of the regular Mitsubishi ‘i.’ The electric motor improved performance and quicker acceleration over the 64-hp gasoline version. The advanced lithium-ion battery is developed by Mitsubishi Motors Corporation
A company called GreenCore Air has released an air conditioner than can be powered by a single 170 watt solar panel. The GreenCore air conditioning unit can heat and cool a 600 square foot room. It runs on DC power, so there is no need to put an AC inverter between the solar panel and
There might be another possibility of producing solar panels – from Cadmium Cadmium Advantages in Solar Panels Silikon based solar panels are facing price growth, so alternative photovoltaic technologies can step into the competition. There is Cadmium, which has several advantages over traditional silicon technology. Those advantages are: The electricity comes from properties of two
I came to this article about the Sunflower’s Fresnel lens . Those lens concentrates sunlight more than 1,000 times, enabling cheaper electricity than traditional photovoltaics. The system is self-powered. Technical specifications: 200-watt system features trackers that shift with the sun’s location, as well as a controller and communications system. The low-slung Sunflower is built to
After the Roadster for 100 000$ which is already available in US, the second car from Tesla is still in developpement ( code name ‘Whitestar’). The second one should cost about half of the first one. There might be a third one – electric car which will cost under 30 000$. Electric car for the
