How to Build a Wind Power Generator video How to Build a Wind Power Generator Harvesting the wind for energy is not a new concept. The origins of using the winds to to produce mechanical energy are lost in the mists of time . Mankind was using wind power to move his ships and grind his grain at least a couple thousand years ago. With the advent of electricity it was only natural to utilise this abundant source of raw power. Early wind turbines in the beginning of the 20Th century provided some of the first usable electricity to farms and businesses before the coming of the electric power lines. VAWT Lenz type. Stage 1. Converting wind power to rotary motion. Update April 2012 The first and foremost thing I must to say is that Edwin Lenz deserves every single bit of credit for this turbine design. check out his website below, this build was based on his designs although I added my own outside the box style thinking to the build design and use of unconventional materials. The wings are basically exactly to Edwin Lenz design specs, with a sign design change to suit the materials I used. I just discovered that the Intro Page has gone missing so I'm doing my best to re write it from memory, plus I want to tell how it has stood up to the weather over the last 3 years and what I would have changed if i was doing it again. This was built to see how this new unique design compared to various vertical turbines, squirrels cages and savonious types just created to much drag at one side that just lost way too much power leaing you with very little torque.
How I built an electricity producing Solar Panel 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. In my attempt to escape city light pollution, I found a great piece of remote 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. I built a wind turbine to provide some power on the remote property. Here is a video of the solar panel set up and in use on my remote, off-grid property. Let me state up front that I probably won't be able to help you out much if you decide to build your own solar panel(s). So what is a solar panel anyway? I started out the way I start every project, by Googling for information on home-built solar panels. After a while, I came to some conclusions: <a href=' seller. A solar panel is really just a shallow box.
PortableApps.com - Portable software for USB, portable and cloud drives Hybrid solar panel (photovoltaic and thermal) I am not going to repeat all the details on how to build a solar panel, there are plenty of other instructables for this (search tool is your friend!). I will give some basics, though... and then focus more on the "hybrid" nature of my panel (PV + thermal). General characteristics: - about 0.5 m^2 area, at a maximum of 1 kW/m^2 of irradiation and 12% efficiency this should produce UP TO 60 W of electrical power. (at the same time this means that about 440 W of thermal power could potentially be harnessed!). Materials: - 36 cells, 3"x6". Build a Savonius VAWT to Make Electricity 2012 Update Once upon a time, I wrote an instructable on this subject and it has changed my life. As things have progressed very slowly, to some it may have appeared that I fell off the planet. To those that know me, it has been a difficult and arduous but rewarding process. I want to thank everyone - over 100 commenters on my original project - for their input and knowledge as well as their questions that lead me further in my pursuit. I will try to take an approach on this project where I will give steps first and explanations of why following.
Homemade Lotion Recipe - How to Make Your Own Lotion If you are still using the cancer-in-a-bottle store bought lotion on yourself or your family, there are super easy natural alternatives! In fact, this recipe is incredibly simple to make and all the ingredients are available here. It only has three basic ingredients and literally takes ten minutes to make! You can customize your lotion to your skin type and desired scent, and you can even make it for baby (calendula and chamomile…) There are endless variations, but some of my favorites are: Calendula and Chamomile for babyRosewater and Almond OilPeppermint, Wintergreen, and Ginger for sore musclesCoconut and Calendula for faceMint and green teaLavender and vanilla I’ve included my basic recipe below. NOTE: This is an improved recipe since many people were having trouble getting the temperatures exactly right to get the lotion to emulsify (as per the comments below). Organic Homemade Lotion Basic Ingredients: Note: All ingredients and many essential oils are available here.

Additional Product Support Information Project Build A Solar Panel: Step by step guide to building a solar panel with complete illustrations Introduction A solar cell's purpose is to generate electricity through the release of electrons from a material that is bombarded by electromagnetic radiation or photons. Most crystalline solar cells are sensitive to visible radiation from 400 - 700 nanometers, which correspond to 3.1 - 1.8 electron volts, of the visible region as shown by ACEPT W3 Group (1999) and also into the near infrared spectrum. As the wavelength of the electromagnetic radiation increases, the amount of electron volts decreases. This means that infrared radiation has less electron volts than the visible spectrum of light (because it has a larger wavelength than visible light) and ultraviolet and gamma radiation has more electron volts than both the visible spectrum of light and infrared radiation (because they have a smaller wavelength than both infrared and visible light). Significance of Solar Panels A solar cell, in itself, is of little value in our energy consumptive world.

Step 1: Marking the pipe The first thing was to mark out the pipe. Step 2: Cutting Once the pipe was marked out i clamped it to the bead of my wood lathe for cutting. Step 3: Marking and cutting the segments. I marked each of the segments 1 1/2" in at each end and used a chalk line to mark a line along the segment. the chalk line did not show up to good so ...
