The ocean is a potentially vast source of electric power, yet wave-energy systems are rare as they generally offer limited efficiency, must withstand battering storms, and need to be tethered to the sea floor. But by applying the principles that keep airplanes aloft, a team of aerospace engineers is creating a new wave energy system that is durable, extremely efficient, and can be placed anywhere on the ocean, regardless of depth.

It provides light where there is darkness, it gives a sense of safety and security, but it's also a power leech. The humble street light. Thankfully, the move away from the grid is already well underway with companies like Urban Green Energy busy transforming these familiar towers of light into self sufficient beacons that harness the power of the elements - in this case, it's a hybrid solution that uses both the wind and the sun.

Has affordable, practical home wind power generation become a reality? The Honeywell Windgate wind turbine from EarthTronics looks like it could be a contender. Developers EarthTronics and Honeywell Corp hope the Windgate wind turbine will help meet the energy needs of homeowners and businesses, even if they are not located in prime “windy” areas. EarthTronics says the 6-foot wide, 95-pound Windgate can start to spin in breezes as low as 2mph and can create more power with less wind than other types of wind turbines. Read More
