WWII veteran creates bird-friendly wind turbine

World War II veteran Raymond Green, an 89 year old resident of Jackson, California, has created a working prototype of a "bladeless" wind turbine which is bird and bat-friendly, and very quiet in operation. Though still in development at present, Green intends his design to be produced in various sizes, from smaller personal versions to much larger turbines which could be implemented in wind farms.

Self-fueled work station concept generates energy while you sit

Unplugged is an office work station of the future concept that envisions powering your electronic devices via energy collected off the human body. The prototype was created by Swedish designer Eddi Törnberg as part of his final year thesis at Beckmans College of Design, in Stockholm, and you will be pleased to know that it doesn’t mean you'd be required to pedal away while you work. In fact all you would have to do is move about your office as normal, sit in your chair and let the heat of your body do the rest. Read More

B9 Shipping developing 100 percent fossil fuel-free cargo sailing ships

Ireland-based B9 Shipping has started work on a full-scale demonstration vessel as part of its goal to design the modern world’s first 100 percent fossil fuel-free cargo sailing ships. Unlike most conventional large cargo vessels, which are powered by bunker fuel, B9 Shipping’s cargo ship would employ a Dyna-rig sail propulsion system combined with an off-the-shelf Rolls-Royce engine powered by liquid biomethane derived from municipal waste.Read More

Wearable device generates electricity from walking knee movements

If you’ve ever worn a knee brace, then you may have noticed what a large change in angle your knee goes through with every step you take, and how quickly it does so. A team of scientists from the U.K.’s Cranfield University, University of Liverpool and University of Salford certainly noticed, and decided that all that movement should be put to use. The result is a wearable piezoelectric device that converts knee movement into electricity, which could in turn be used to power gadgets such as heart rate monitors, pedometers and accelerometers.Read More

Honda "smart home" showcases off-the-grid energy solutions

Honda has unveiled a demonstration house in Saitama, Japan, to showcase and test its new Honda Smart Home System (HSHS). Featuring a line-up of innovative energy production, management and conservation solutions, the company hopes HSHS will free homeowners from the constraints of on-grid living somewhat, give them a leg up on self-sufficiency when disaster strikes and help reduce carbon dioxide emissions both at home and on the road by networking electric vehicles into the mix.Read More

Nanocrystal-coated fibers show promise for harvesting waste heat

Researchers at Purdue University in the U.S. have developed a new method of harvesting vast amounts of energy from waste heat. Using glass fibers dipped in a solution containing nanocrystals of lead telluride, the team led by Dr. Yue Wu is engineering a highly flexible thermoelectric system that generates electricity by gathering heat from water pipes and engine components.Read More

Less power to cell phones, more power to the people

Smart phones are techno wonders, and they are also energy guzzlers, which is not a problem for people living in the developed world. However, their high energy requirements has stymied the adoption of mobile internet services in developing countries where mobile internet can be a real lifeline. In Africa, for example, few people can access the internet from a wired connection but 90 percent of the population lives in areas with mobile phone network coverage. There’s one problem though. Access to the power grid in Africa is limited.Read More
