GREEN TURBINE. Green Turbine is a small (slightly larger than a football) steam-driven turbo generator that converts (waste) heat into electricity. The energy not converted to electricity is available for heating or cooling. Green Turbine-powered heaters enable any homeowner or small business to produce 100% of their heating and hot water needs at a huge savings while generating up to 80% of their electricity needs, free of charge. It will also reduce their CO2 emissions by 50%.
The Hottest Home-Improvement Technologies and Trends: Residential-use wind turbines are becoming smaller, more efficient and hopefully more mainstream. This model is just 6 feet tall, 185 pounds and can start producing energy in a wind less than 1 mph. It has an auto-shutoff at 38 mph so noise and vibration are not an issue.

Kepler Energy has announced plans for a 30 MW tidal energy fence to be built in the Channel. With an estimated cost of £143 million (US$223 million), the underwater fence would be built in the water somewhere along the line between Aberthaw and Minehead and could be operational by 2021. | via gizmag
