Ted Baer's Bicycle Wheel Windmill. Ted Baer has created a series of small windmills designed for third world use over a period of three decades. This first in the series has evolved in simplicity and power. The aluminum vanes are constructed from a building flashing roll utilizing the pre-existing bend of the roll in construction. Two 16 " sections are riveted together to make one vane. The vanes clip on the spokes of the bicycle wheel using a "bent nail" and a bend in the vane. Detailed pictures will be provided shortly. The generator is a surplus permanent magnet motor and the uv resistant endless belting is purchased to length from online sources.

Output is a respectable 2 amps at 12 mph (18-20 volts) providing a cost effective alternative to a solar photovoltaic panels (if wind is available). The windmill does have a tail (see new photo). The generator is a 24 volt DC permanent magnet motor. The generator is mounted using a simple L bracket. The windmill pole is electrical conduit that 1.5 inch PVC slides over. Lenz2 wind turbine. This instructable will show you how to build a Lenz2 wind turbine from materials you have around the house.

The design was developed and tested by Ed Lenz of The Lenz2 VAWT (Vertical Axix Wind Turbine) is 4 foot tall and 3 feet in diameter. It is a basically a Savonius style turbine but with the refinement that the three wings are shaped to provide lift as well because or their teardrop configuration. In the above link Lenz describes how he placed an ananometer inside the stational turbine and showed that the windspeed picked up passing past the solid portion of the wings. In my design I scaled down the diameter to approximately 18 inches and the height to 21 inches.

I was able to use materials I had on hand to build the turbine. [Note: Since this instructable was published, I learned more about how the wings should be shaped. Construire une éolienne à axe vertical. Accueil » Fiches techniques » L'énergie et la motorisation Présentation Cette fiche contient les plans pour vous fabriquer une petite éolienne à vitesse constante. Le but est d'arriver à la faire avec du matériel de récupération. Elle est capable de faire débiter entre 600 et 700 watts à un alternateur par un vent de seulement 30 km/h.

Principe de fonctionnement Quatre pales en forme de godet tournent sous l'action du vent (fig. 10). Liste des matériaux Construction des pales Elles sont au nombre de quatre et sont taillées dans de la tôle de 2 mm d'épaisseur. Les supports de pales Support inférieur Support supérieur La croix de liaison Biellette et accessoires Le socle Il se compose de quatre pieds reliés par deux plateformes. Position des pales en fonction du vent Principe Pour la suite Pour que l'éolienne puisse faire tourner un alternateur il faut rajouter une poulie U à gorge trapézoïdale sous la plate forme inférieure.

Auto-construction d'une éolienne. How to- Wind Turbine Made from Scrap Metal... This is my first Instructable so bare with me. This following Instructable is for A Wind Turbine that i Designed and Made out of Salvaged and Recycled Materials Because of the nature of the materials,everybody building them this way will all be different, don't let how i made this turbine affect how you make yours. build it with what you got. Wind turbines are not only Great to make but if made right can be good source of electricity. The way i will be using this Electricity is this. This is a simple wind turbine Design that i built in less than 1 day. MATERIALS (I cant really give any specific lenghs and sizes because... everybody is going to be different ... (ill keep this instructable just about the turbine for now so at this point i wont include all the batteries and instruments like the inverter or the voltage regulator) I should also mention This Turbine Project Costed Me 'Little to Nothing' I used Basic Tools In building this Wind Turbine Stay tuned for Power Output Readings.

DIY Wind-Powered Water Pump. The biggest problem with this wind-powered water pump design is that every single part of the assembly is a bit wobbly, and all the wobble eats up a lot of the wind energy that should instead go into pumping water. To solve this problem in the next version, I would: 1. Use a sturdier tripod. 2. Use a bicycle rim that isn't warped.

The bottom rim in this project is badly bent from some bike accident, and the motion it makes wastes wind energy. 3. Use tin or PVC for the wind foils and attach them directly to the bicycle wheel rims. Any solutions to the above would be appreciated. Unique Wind turbine. Very adaptable design. How to build a wind turbine. Here we are going to make the two disks that the turbine blades fit on. First of all, mark a centre point on your MDF board. Use a compass to draw a circle with a radius of 160mm. Using a band saw, cut the circle out and use a sander to smooth the edges. Trace around the circle and use it to produce another disk of the same size. Find the centre point of these circles and use it to draw a 5 pointed star on each one. These lines will be used to align the turbine blades further on in the project. At the end of this step you should have 2x MDF circles split into 5 segments.
