Here’s another thing that follows the same general idea as the Flying power from last week. This time they are using lighter then air helium to raise the blimp to over 330 meters above the ground. Like the other ones, it transfers its power to the ground via cables (come on science, invent wireless electricity already). However this one looks to be more stable in the air, considering it’s a blimp, and not a helicopter Detail... (Technology not D.I.Y)

Making and using a solar cooker
By Joe Radabaugh From http://www.backwoodshome.com/articles/radabaugh30.html
It was during those days that I saw my first solar cooker and began the hobby that led to the cooker described in this article. I started out building the most efficient styles I could come up with. Later, while keeping this efficiency, I strove to simplify the building process, the materials needed, and the actual use of the cooker. The cooker is now basically cardboard, aluminum foil, and glass. Yet, because of the design, it is remarkably efficient and durable.
It looks so simple now, but you should realize that this simplicity took years of effort and many accidental breakthroughs. The testing for this cooker is now complete.
What I have included here is a very good starter model that can lead you and your family to a lifetime of enjoyment without threatening your pocketbook. A solar cooker can easily be built for under $10. Detail...

How Biodiesel Is Made
by Graydon Blair from Utah Biodiesel Supply
Biodiesel is made by chemically altering an organic oil (typically vegetable oil) through a process called "transesterification". Essentially, the process thins down the oil to allow it to run in an unmodified diesel engine. Detail...

Double-Angled-Twelve-Sided (DATS) Solar Cooker
by Teong H. Tan Link...
DATS cooker employs 24 small reflective panels to concentrate extra sunlight to compensate for the heat loss from not using a plastic bag. DATS cooker design is similar to a deep-focus parabolic cooker, but instead of using a true parabolic curve, multiple flat panels concentrate sunlight onto the cooking pot. Two reflective surface-angles, 45º and 60º, are used so that a bend can be introduced in between for structural rigidity to hold the cooker’s shape. This structural rigidity allows for DATS cooker to be constructed out of cardboard material.
A DATS cooker, tested in Shanghai, reached a maximum temperature of 140ºC (284ºF) inside an empty black cooking pot, on a clear sunny day with 21ºC (70ºF) ambient air temperature and a slight breeze. Eggs became hard-boiled in 30 minutes and two cups of rice cooked in 95 minutes. The cooker should be re-positioned every 45 minutes or less for better efficiency. Detail...

Build your own solar thermal panel from garbage dump
From Instructables.com Source The Sietch
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 produce useful effects, in this case hot water. You can use these instructions to build a device that will actually heat enough water to use in the home, but it would require modifications. Detail...

garage heat - just drink a lot of soda
From Hemmings Auto Blogs
I’ve had a few days during the HMX build while I’m either waiting for parts or waiting for something to dry and had some free time. I’m not exactly one to sit and watch TV when I have nothing planned, so I set out on another project.
While I have electricity out to the garage now, heat has been an issue all winter long. Mattar graciously lent me his kerosene heater, which did an okay job of taking the bite off the chill. Insulating the garage would go a long way to help keep the bitter Vermont cold out, but that’s a project for another day. More...

A Homemade Solar Water Heater
From Motherearthnews.com
Last summer my family and I started digging out the foundation for our new home. However, after only two sweaty days of laboring under the Florida sun, I realized that we might be going about the whole project in the wrong order. Maybe, I thought, we should be erecting the solar water heater and shower — which we'd already planned as part of our new homestead — before actually constructing the house itself! Well, the more I considered this notion, and the more layers of grime that built up on my tribe's bodies, the more that bit of backward logic began to make a frontward kind of sense. Detail...

MiniMill: DIY wind turbine - small stepper motors
From: TheBackShed.com
The Mini Mill is a fun little weekend project, and can be used to light a LED, small light bulb, or even charge a couple of NiCad batteries.
It is not necessary to build your own complex and expensive alternator for a small DIY wind turbine - small stepper motors can be perfect for the job. Found in old computer printers (dot matrix, daisy wheel, and some laser), stepper motors are cheaply (if not freely) available and generate AC power at low rates of rotation (far lower than similarly sized DC motors for example). Therefore small wind turbine blades can be mounted directly onto the motor shaft rather than through a noisy and complicated gearing mechanism. Small stepper motors (i.e. under 1 inch diameter) are only really useful for powering a couple of LEDs, larger motors can be used to recharge batteries and much more. Detail...

Electricity producing Wind turbine
From: Michael Davis at mdpub.com
Several years ago I bought some remote property in Arizona. I am an astronomer and wanted a place to practice my hobby far away from the sky-wrecking light pollution found near cities of any real size. I found a great piece of property. The problem is, it's so remote that there is no electric service available. That's not really a problem. No electricity equals no light pollution. However, it would be nice to have at least a little electricity, since so much of life in the 21st century is dependant on it.
One thing I noticed right away about my property is that most of the time, the wind is blowing. Almost from the moment I bought it, I had the idea of putting up a wind turbine and making some electricity. This is the story of how I did it. Not with an expensive, store-bought turbine, but with a home-built one that cost hardly anything. If you have some fabricating skills and some electronic know-how, you can build one too. Detail...

Homebrew Hydro Electric
Source : Otherpower.com
Scotty's new homebrew hydro plant, using a Banki Turbine design built from scratch. The generator is a homebuilt permanent magnet alternator, very similar to our Brake disc alternators. In a Banki design, the water hits the vanes twice, once upon entrance and then again upon exit. There is only about 3 feet of head available at the site, and the system is producing about 2 amps at 12VDC, fed by a 4 inch pipe. Detail...

DIY 1000 watt wind turbine
From: instructables.com
We built a 1000 watt wind turbine to help charge the battery bank that powers our offgrid home. It's a permanent magnet alternator, generating 3 phase ac, rectified to dc, and fed to a charge controller. The magnets spin with the wind, the coils are fixed, so no brushes or slip rings necessary.
