- Giant rubber snakes to capture wave power?
- UK researchers have developed a prototype of a future giant rubber tube which could catch energy from sea waves. The device, dubbed Anaconda, uses 'long sea waves to excite bulge waves which travel along the wall of a submersed rubber tube. These are then converted into flows of water passing...

- Diamonds are jet engines' best friends
- You certainly know that birds are enemies of jet engine turbine blades. But these jet engines have another nasty foe: sand. Even if the turbine blades are protected with thin layers of thermal barrier coatings TBCs, they operate at very high temperatures. When a sand storm hits a blade, grains...

- Interconnecting wind farms
- Wind power is one the world's fastest growing electric energy source, but as wind is intermittent, a single wind farm cannot deliver a steady amount of energy. This is why scientists at Stanford University want to connect wind farms to develop a cheaper and reliable power source. Interconnecting wind farms...

- Hydrogen turbines generate clean electricity
- The Lawrence Berkeley National Laboratory LBL has developed near-zero-emission gas turbines using pure hydrogen as a fuel. But because this LSI (low-swirl injector) technology also can use other fuels, it has the potential to help eliminate millions of tons of carbon dioxide and thousands of tons of nitrous oxides NOx...

- Eco-friendly ice creams
- According to The Scotsman, Mackie's of Scotland has bought 3 wind turbines for £2.5 million to produce ice creams made with 100% renewable energy. The two new turbines ('Ice' and 'Cream') will join the existing one ('Mackies') and make enough 'green' electricity to produce every tub of ice cream sold...

- A new tidal generator design
- What happens if you run an electric motor backwards? In short, it stops being a motor and becomes a generator. Following this principle, researchers at the University of Southampton have built a new kind of tidal stream generator. Their simple and elegant design has fewer parts than most current tidal...

The average american household uses 14,000 kWh/year, about 1,200 per month in round numbers, meaning a 6kWh generator is about the right size--assuming the wind never dies.I couldn't find prices for Proven Energy, but a Quiet Revolution 6kWh unit costs...

- Towards low-cost LED lighting
- You all know that incandescent bulbs are pretty inefficient, converting only 10% of electricity into light -- and 90% into heat. Light-emitting diodes, or LEDs, could soon replace incandescent and compact fluorescent bulbs in our homes. They are more efficient and environmentally friendly. But LED lights are currently too expensive...
