DIY wind turbine project goes open source If you live in an area that sees a fair amount of wind and you’d like to reduce your utility bill by harnessing some of that wind power, a wind turbine might be a good idea. The trouble with most commercially made home wind turbines, though, is that they’re fairly expensive, extremely tall and, if you have neighbors, they might not appreciate the new addition to the neighborhood. Washington state resident and do-it-your-selfer Make Marohn came up with an inventive alternative. It’s called The Zoetrope and it’s a vertical-axis wind turbine made out of easily attainable parts and, according to this article, it can be assembled by just about anyone. Applied Sciences indicates Marohn’s intention for this project was to reduce his water heating bill. So, he set out to make a wind turbine that could harness the winds of the Pacific Northwest and put the energy to work for him.

Make a Wind Generator Make: Projects With a motor and some piping, it’s easy to enjoy free energy forever. There are no limits to what you can do with wind power. How I built an electricity producing wind turbine 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. My amazing DIY solar generator I remember the inspiration for building my solar generator clearly. It was close to 20 years ago and we were camping at the dunes in Oregon. Our campground neighbor, in a huge RV, ran his generator for about two hours one evening. It was annoying beyond compare — we go camping for peace and quiet. We later found out from overheard conversations that the RV people were using the gas generator to charge their camcorder. Apparently they did not have a DC adapter or know about a thing called an inverter.
Wind Power Generators Annual Output (KWH/year) = 0.01328 (D^2) (V^3) source... Where D^2 is the blade diameter in feet squared, and V^3 is the wind velocity cubed in mph -- this is the year round average wind speed -- see wind maps below. So, a 10 ft diameter wind turbine in 12 mph average winds might produce about (0.01328)(10^2)(12^3) = 2300 KWH/year Note that the energy produced is proportional to the cube of wind speed -- having enough average wind speed is everything in wind turbines. Use the wind maps discussed below and a wind survey of your site to determine if a wind turbine will actually payoff.
Make your own solar power generator for less than $300 Whether you live off grid or just want backup power for emergencies, having a small solar generator at home can definitely come in handy. While most store-bought solar generators can be pretty pricey, you can actually create your own with parts easily acquired through the internet or at local stores for $200 to $300 – and you don’t have to be an engineer to do it. An online tutorial created by Phil Heiple features easy-to-follow instructions with amusing illustrations that guide you through each of the eight steps. Once you obtain the parts, which include a small solar panel, a battery, a DC input and an AC inverter, assembly takes about an hour to complete. When you're done assembling your new DIY solar power generator, place the solar panel in the sun for five to eight hours to charge the battery the first time.
DIY wind turbine beats solar on price You may have heard of William Kamkwamba, the Malawian teenager who built a wind turbine out of spare bicycle parts and scrap metal and wood. His turbine provided electricity in his home for the first time and allowed them to replace smelly, expensive kerosene lamps In 2001 his family couldn't afford the cost to send him to school, but he didn't let that stop him from teaching himself the basics of electrical engineering out of an old school book and building a wind turbine that powered four lights, two radios, and a cell phone charger. He built his own homemade light switches and circuit breakers and has dabbled in radio transmitters. Mr.
Off-Grid Power Off Grid System This section is dedicated to off-grid power as well as back up power systems. Articles: Brooks Solar Living Off Grid – 12/10/2010 Build Your Own Generator – 12/10/2010 almost free garage heat – just drink a lot of soda 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. I decided instead to take advantage of the south-facing side of the garage and build a solar furnace to collect some of that sunshine just bouncing straight off my garage.
My Home-Built Solar Panel Projects I am a person who loves to build things. I'd rather build something than buy it, if I can. Even if it something inexpensive, I like the challenge of figuring out how to build it myself, rather than just buying it and being part of the mindless consumer culture.
