Silent rooftop wind turbines could generate half of a household's energy needs

Silent rooftop wind turbines could generate half of a household's energy needs
Small wind turbines scaled to the right size for residential and urban areas have so far lived in the shadows of their larger wind-farm-sized counterparts. The power output has been too low for a reasonable return on investment through energy savings and the noise they produce is louder than most homeowners can deal with. A Dutch renewable energy start-up called The Archimedes is working to solve both of those problems in a new class of small-scale wind turbine -- one that is almost silent and is far more efficient at converting wind into energy. The company states that the Liam F1 turbine could generate 1,500 kWh of energy per year at wind speeds of 5m/s, enough to cover half of an average household's energy use. When used in combination with rooftop solar panels, a house could run off grid. The Liam's blades are shaped like a Nautilus shell. “Generally speaking, there is a difference in pressure in front and behind of the rotor blades of a windmill. Related:  Eco-home

You can consume a kilowatt hour in about 50 minutes with a microwave oven, or five hours with a large television. Over the course of 80 minutes on a treadmill your body can burn a kilowatt hour’s worth of food energy—about four chocolate donuts, or one double cheeseburger. Depending on where you live, it costs more than a quarter or less than a dime. The Wood 103 This page is all about a rather silly, quick project where in about 1 day I built a small wind generator using the following items, and nothing else.... (1) Wood (2) Copper wire (3) Surplus Neodymium magnets (4) Dirt (5) 10" piece of 3/8" steel shaft (6) Two bolts, but these are optional. ...and that's all, unless we count glue, and linseed oil which I used for finishing. Pictured above is one of the magnets I used. Above you can see the armature for the alternator. Pictured above you see the wooden pillow block bearings. The stator, on which the coils are wound was cut from two pieces of 2" X 4" lumber. I dragged a magnet around in the dirt of my driveway, so that it would attract the magnetite sand. The dirt was mixed with epoxy, so that I had a thick paste. The completed alternator! To stay with the "style" of the project I decided to build the whole windmill out of wood, it's a fairly simple design and should be self explanatory. The prop is wooden, made from 1" X 4" lumber.

Ruling says Chinese solar panels pose risk to Canadian industry After months of deliberation by two government bodies, a final decision has been released ruling that Chinese solar panels are being dumped into Canada and they could damage the Canadian solar industry. The judgment – issued by the Canadian International Trade Tribunal on Friday – said that dumping and subsidizing of some Chinese-made solar panels have not yet hurt Canadian panel makers, “but are threatening to cause injury to the domestic industry.” That means that provisional duties imposed on some Chinese companies by the Canada Border Services Agency – the other body looking into the case – will be refunded, but tariffs will apply from now on, said lawyer Thomas Timmins of Gowlings in Toronto. The CBSA’s provisional duties, set in March, ranged from 9 per cent to 286 per cent, depending on the specific Chinese manufacturer. The final tariff levels have not yet been revealed. The Canadian solar industry has been divided about the imposition of import duties. Mr. Report Typo/Error
