One of the two small turbines is visible below the front aerodynamic solar-panel. The center light detaches for use as a flashlight. In shape or not, pedaling up a steep or long hill can knock the wind out of most of us. That is one reason, says designer Chen Chun Tung, we need bikes like the Wind-Solar Energy Bike. The design, he says, converts and... Read full Wind Watch Article

A blast from the past: Flower power returns A blast from the past: Flower power returns

The flower, by Art Energy Design, is a renewable energy display with solar cells attached to leaves while the flower petals act as a rotor to turn a 6V generator. Both charge a battery in the base that stores enough energy to keep the display lit by LEDs at night. The Pittsburgh Power Flowers Project says it combines sustainable energy devices with... Read full Wind Watch Article

Small power transformers handle 5 to 15 MVA Small power transformers handle 5 to 15 MVA

The recent line of small power transformers is customized for use in municipal power substations. The utility-focused smaller power transformers, from Pacific Crest Transformers, Medford, Oregon, are rated from 5 to 15 megavolt-amperes. They are ruggedly built, using disk-wound coils with cruciform miter-cut cores and proprietary 360° cooling ducts.... Read full Wind Watch Article

Vestas adds $100 million in wind turbines to Canadian wind plant Vestas adds $100 million in wind turbines to Canadian wind plant

Wind turbine manufacturer Vestas Americas has announced that it received an order for 18 V90-3.0 megawatt wind turbines to be installed on a Canadian wind plant. The buyer — TransAlta Corp., of Calgary, Alberta — plans to expand its’ existing wind farm in New Brunswick, Canada, where 32 wind turbines were installed in 2008. TransAlta estimates... Read full Wind Watch Article
