The world’s largest wind turbine is now the Enercon E-126. This turbine has a rotor diameter of 126 meters (413 feet). The E-126 is a more sophisticated version of the E-112, formerly the world’s largest wind turbine and rated at 6 megawatts. This new turbine is officially rated at 6 megawatts too, but will most… [Continue Reading]
Note: If you looking for AA-sized LifePO4, you can find them here. Soon, we’ll probably be seeing Lithium Iron Phosphate (LiFePO4) batteries being used in most electric cars and bikes. This new battery type is set to dominate the market. Based upon lithium ion technology, LiFePO4 batteries offer many advantages over lithium cobalt dioxide (LiCoO2)… [Continue Reading]
Note: This post has been expanded and updated for 2009! Tankless water heaters only heat water when it is needed. About 8% to 30% of the energy consumed by a standard water heater goes to keeping the water hot while it’s not being used. New tankless systems heat the water instantly when you turn on… [Continue Reading]
Masanori Naruse jogs every day, collects miniature cars and feeds birds in his backyard, but he’s proudest of the way his home and 2200 others in Japan get electricity and heat water – with power generated by a hydrogen fuel cell. The technology – which draws energy from the chemical reaction when hydrogen combines with… [Continue Reading]
Note: Images and Video © Lucid Dream Productions Wind turbines designed to be installed on rooftops are generating a lot interest lately. These compact turbines can be located on top of buildings, or attached to other parts of large structures like bridges. In turns out, though, that installing wind turbine in a city environment is… [Continue Reading]
Yesterday, GM and Segway unveiled an electric-powered urban vehicle called the Puma. The Puma seats two people, and is said to reach a top speed of 35 miles per hour. The vehicle can go 35 miles before needing a recharge. Larry Burns, vice president of research and development for GM, said it would cost about… [Continue Reading]
We’ve seen prototypes for solar-powered cell phones, but now a Chinese company claims to have developed the world’s first commercially available solar-powered cellphone. The company says a scale-like solar panel on the top side of the phone can also be recharged by light from artificial sources. It can provide 40 minutes of talk-time after sitting… [Continue Reading]
A Canadian company, Pulsar Advanced Technologies, claims to have produced a water heater that uses microwave technology to heat water instantaneously. The company says: “The Vulcanus MK4 can heat water from 35 degrees Fahrenheit to 140 degrees Fahrenheit in seconds and can source multiple applications at once: showers, dishwasher, sink usages and more. The Vulcanus… [Continue Reading]
LED TVs are a type of LCD TV that use LED lights to illuminate the screen. In full-array LED TVs the light emitting diodes are embedded across the entire back of the panel, while other models are edge-lit, where the LEDs are arranged around the sides of the panel and illumination is directed toward the… [Continue Reading]
LEDs offer the best energy efficiency of any widely available lighting technology. And LED lights contain no mercury, as opposed to the compact fluorescent bulbs that have become so common. But recent reports suggest that LEDs may have their own issues with hazardous substances, so should you steer clear of them? Not so fast –… [Continue Reading]
