Wind turbine, Rooftops and Plugs on Pinterest. Build this open source DIY wind turbine for $30. Getting started with home wind energy projects can set you back a pretty penny if you buy a finished product, but if you're a little bit handy and don't mind scrounging for materials and getting creative in the garage or backyard, you can try your hand at building one of these DIY wind turbines for about $30 in materials.
After all, it is #iheartrenewables week! We've previously covered Daniel Connell's open source concentrated solar collector plans, but now he's back with another great DIY renewable energy project, a vertical axis wind turbine based on the Lenz2 lift+drag design. Connell's design calls for using aluminum lithographic offset printing plates to catch the wind, which he says can be obtained cheaply (or possibly even free) from an offset printing company, and a variety of hardware and a bicycle wheel. "The turbine uses the ~40% mechanically efficient Lenz2 lift+drag design. Home - The Archimedes. New Urban Mini Turbine for lantern poles introduced - The Archimedes. 27 May 2014 | On the market launch of its ‘big brother’ – the Liam f1 – R&D company the Archimedes introduced a smaller version as well: the Liam Pole Mini Urban Wind Turbine.
With half its size (ø 0.75cm) it will be mounted on a Cradle-2-Cradle lantern Pole manufactured by Sapa Pole Products. This new Product Market Combination (PMC) has the potential to save a lot of money on electrical infrastructure. When combining the Liam Pole urban mini wind turbine with a set of solar panels (PV), a LED lantern pole becomes totally self-sufficient.
During daylight the solar panels and the turbine will charge a battery which will supply the light emitting diodes (LEDs) during night time, supported by the Liam turbine when enough wind is at hand.

While commercial wind turbines have been trending toward larger sizes, from 300 kW capacity in 1990 to 7.5 MW in 2011, sometimes it is worth bucking the trend.
Professor J.C. Chiao and his postdoc Dr. Smitha Rao of the University of Texas at Arlington have taken this contrarian philosophy to the extreme. They have developed a MEMS-based nickel alloy windmill so small that 10 could be mounted on a single grain of rice. Aimed at very-small-scale energy harvesting applications, these windmills could recharge batteries for smartphones, and directly power ultra-low-power electronic devices. The micro-windmills (technically called horizontal axis wind turbines) have a three-bladed rotor 1.8 mm in diameter mounted on a tower about 2 mm tall. Despite their size, the micro-windmills can endure strong winds, owing to being constructed of a tough nickel alloy (rather than the silicon and silicon oxide layers typical of MEMS designs) and smart aerodynamic design.
Let's get to the meat. Building tops to house urban windpower. The southern hemisphere's largest ever Windpod system has been installed on the City of Cockburn's administration building in Spearwood, as part of a joint research trial with Windpods International.
Twenty Windpod turbines have been installed on the building – facing south-west to harvest the most wind – and are expected to generate 4.5 megawatt hours of power each year. It follows their first commercial installation on the roof of the City of Fremantle's council chambers in 2009, after early development was conducted in and around Fremantle and the University of WA's wind tunnel.
Originally invented by Fremantle resident Graeme Attey, Windpods are small-scale, drum-style wind turbines designed to suit urban environments. "Wind turbines work by converting the kinetic energy in the wind into mechanical power and Windpods use this power to drive a generator situated at the end of each turbine," City of Cockburn climate change officer Jennifer Harrison says.
Cockburn Mayor Logan K. Small-wind-turbines. Small Wind Guidebook. Wind systems. The amount of renewable electricity harnessed from the wind is growing rapidly.
Australia has an abundant wind resource, which, if used to generate electricity, could save significant greenhouse gas emissions. To take advantage of this resource, turbines must be installed in open sites on sufficiently tall towers. Appropriate wind system locations Begin investigating wind technology by ‘reality checking’ your general location. Wind generators need ‘clean’ and sufficiently fast wind to produce electricity. Coastal locations, and flat rural areas without significant vegetation or buildings, offer the most laminar wind flow. Urban areas have a poor wind resource that is usually extremely turbulent. Urban areas have a poor wind resource that is usually extremely turbulent. Wind systems installed on roofs typically do not produce much electricity, have short life spans and are thus never economically sound.
List of Top 5 Micro Wind Turbines Needs a Second Look. Clean Power Published on April 30th, 2013 | by Tina Casey One of the most popular micro wind turbine companies around, Southwest Windpower, began to scale back operations last year and has apparently closed its doors, which means that our list of Top 5 Micro Wind Turbines is overdue for a re-do.
