The SolarFlower Project has free Do It Yourself (D.I.Y.) Plans for Building your own Solar & Wind Energy Collectors!

At Last! Something practical: that you might be able to build for Yourself!

The Solarflower is an open source solar energy collector which tracks the sun automatically through a simple non-electrical mechanism.

It can be made almost anywhere from common recycled and salvaged materials using basic tools and skills, is portable, has no running costs or emissions, and can produce up to kilowatts of power per device.

Depending on available resources it should take one to three unskilled people less than a week to build, and cost under $100.

Potential examples of use could include:

    Electrical production with simple steam turbine/piston, with waste heat going to oven or hot water system.
    Dome oven with integrated water system for temperature regulation and hot/pasteurized water.
    Steam distillation of water for removal of chemical, heavy metal, and biological toxins.
    Medium to large scale food dehydration, processing, and roasting.
    Conversion of fibrous organic waste into charcoal for energy storage and low smoke cooking, with coproduction of bio-oil and bio-gas.
    And any other application utilizing heat.

Vertical Axis Wind Turbine v1.0 (VAWT)

Video For the Detailed Tutorial is here:



This is a Vertical Axis Wind Turbine which uses wind energy to drive things like an alternator/generator for producing electricity, or air and water pumps for cooling, irrigation and similar.
The turbine uses the 35-40% mechanically efficient Lenz2 lift+drag design. It is made almost entirely from scrap materials, and should cost about $15-$30 for the six vane version, which can be made by two people in four hours without much effort.
The three vane version has been successfully survival tested to 80 km/h sustained winds and the six vane version to 105 km. Both will do more, but exactly how much has not yet been ascertained. The current longest running version has been up since early 2014, through reasonable storms, with no noticeable wear and tear as of yet.

Full power curves have yet to be calculated for this particular build, but according to Mr Ed Lenz's calculations a six vane at 0.93 meters diameter and 1.1 meters high with a 90% efficient alternator should produce at least 135 watts of electricity in a 30 km/h wind, and 1.05 kilowatts at 60 km/h.

The materials listed in this tutorial are to make the three vane version. Double everything except the bike wheel for six vanes.
