Amazing Green Inventions!!!
1) FRICTIONLESS WIND TURBINES: The problem with wind turbines? Often, it's just not windy enough to get them turning. It's not really the lack of wind that is the problem, but the friction in the turbines themselves. Chinese scientists may have cracked this problem with the first "magnetic levitation" (or MagLev) wind turbines, which replace ball-bearings with the technology used in advanced monorails, making a frictionless turbine that can generate electricity from winds as low as 1.5m per second. They're ideal for low wind areas, such as mountain regions and small islands. The MagLev wind turbines could also use the airflow caused by passing cars to generate roadside lighting.
2) THE ECO KETTLE: It is estimated that, on average, we boil twice the volume of water needed every time we use our kettles. With a 3kW kettle that's the same as wasting the energy of around 50 light bulbs. And standard kettles are often highly inefficient - a stove-top kettle, for instance, requires energy to heat the handle and shell in addition to the water. But British designer Brian Hartley's Eco Kettle solves these problems at a stroke. You fill it up, and then use the measuring button to release the exact amount of water you require - from a single cup to a full jug - into a separate chamber for boiling. It is also insulated to keep the water hot. The result is an energy saving of up to 30 per cent.
