Faroun Lenz v2/Delta is basically taking lenz v2 and Delta’s hard work and changing it to work with my twisted mind….
keep in mind that this one is easier to build than my Savonius.
i kept it very basic.
to build the turbine, you need the following material:
-3 bicycle 29" wheels
-12 lamm…

Ground source heat pumps (GSHP) transfer heat from the ground into a building to provide space heating and, in some cases, pre-heating domestic hot water. For every unit of electricity used to pump the heat, 3-4 units of heat are produced. As well as ground source heat pumps, air source and water source heat pumps [...]
A wind turbine must have a clear shot at the wind to perform efficiently. Turbulence, which both reduces performance and “works” the turbine harder than smooth air, is highest close to the ground and diminishes with height. Also, wind speed increases with height above the ground. As a general rule of thumb, you should install [...]
The Homebuilt Dynamo (as wired in this book) can be used from 12v to 36v with a top rated output of 1000 watts - 28 amps and 36 volts at 740 RPM.
The following is taken from the introduction to The Homebuilt Dynamo
Why this book?
1969: Decided to live the simple life. Bought a few acres of [...]

How to build a Solar Powered Trike
The purpose of this project is to build a vehicle that:
-Provides free, ‘green’ transportation for short distances (<10 miles), thus it must never

Goal: build a Savonius wind turbine made out of cardboard to see what
works. This is for the turbine only and not the generator itself. The main photo you see is the goal.
The need for a working model grew out of frustration trying to
jury-rig various designs of a Savonius turbine that in the end…

I’ve been feeling fantastic lately, and also not eating that much. I figure energy in = energy out, and this feels great, so I’m going to stick with it.
I’ve also long wanted to see what it’s like to live on notmuch, like half the world does. I already don’t spend a whole lot, but I’m sure it’s m…

This is a parabolic cooker I built a while ago, so unfortunately I can’t show step by step photos of it’s construction. However, it’s relatively easy to see how it was put together.
It makes a great science project. Unlike most, you’ll actually get some use out of it afterwards. Some of the princi…

This project will create a DIY solar hot water heater for less than five dollars (if you have access to a garbage dump). It will allow you to see the principles of solar water heating in action, and is highly customizable.
Its a great way to learn about using the renewable energy of the sun to p…

This is another good use for the solar panel used on the huge amounts of garden LED lights around, coupled to a portable radio that runs off 2 or 3 AA cells.
Most of us have an old radio lying around, so I based the $5 price on the cost of purchasing/ acquiring a solar powered garden L.E.D light.
