With the population of the world growing larger by the minute, certain resources are becoming scarce, causing people to learn how to conserve and recycle. In other words, many people are turning to alternatives. Cars are being run off of fuel made from corn. Some are even run straight from electricity, which leads me to the point of this article: People are even turning to alternative sources of energy to power their homes, with wind power being one of the most popular!
So, how do you make wind power? Obviously, you will need a wind generator, which is basically a typical windmill. This is something that anyone can build right from scratch, using supplies that can be found at your local hardware store. In fact, you could build a windmill for less than $200, and even cheaper if you decide to incorporate recycled parts into your windmill.
Of course, in order to build a windmill properly, you will need to find a great set of instructions, because let’s face it: I don’t think the bulk of us could just figure out how to build one without having some sort of instruction to follow!
Having a great blueprint to follow will ensure that your windmill will be built properly and in perfect working order. Without a good set of instructions, you might not be able to figure out what problems you may have if your windmill doesn’t work or breaks down. You will also know what you can expect from your windmill, such as what you can power and the amount of power you can generate.
If you in search for instructions on how to build your own windmill, check out How to Build a WindMill. It is a complete guide that provides full, detailed instructions on how to build your own windmill!

Powermonkey-eXplorer portable solar charger uses the sun to power iPods, cell phones and other devices
Solar-powered outdoor gear seems all the rage these days, and with good reason. Harboring the useful power-generating abilities of the sun is an idea whose time has come, especially if out hiking, camping or anyplace where one can’t just plug…
Now that scientists can look at events the happen on a femtosecond time scale, they will be able to fully understand how plants convert sunlight into energy. Will this improve our solar energy technology?

I’m having a outdoor fish tank but not possible to have electical supply to power a water filter till there. But it’s often quite windy out there, so was having this crazy idea to build a windmill to power a water filter. Possible? How? Where to look for help?
Thanks
Also have many suggestions that I should go for Sloar-powered instead.. but as mine will be outdoor and open to public excess..so there’s also fear that the solar-panel will be easily stolen..sigh.

Rooftop wind turbines offer a relatively inexpensive way to participate in the rush to renewable energy. The principle allure is low installation cost. Typically, tower installations for larger turbines add 50-80% to the cost of the system. With a rooftop turbine, an $800 tower is replaced by a $39 roof mounted tripod, or a length of pipe attached to the side of the house.
According to Ron Stimmel of the American Wind Energy Association, “…rooftop turbines still account for only 1 percent or so of the 10,000 small wind turbines that are sold each year in the country.” For this reason, few performance statistics are available from actual owners.
It’s possible, however, to get an idea of the estimated power output of a rooftop turbine from the manufacturer’s website. For example, the Energy Performance chart for Southwest Wind power’s 200W Air Breeze predicts 20-30 kWh (kilowatt hours) per month from 10-12 mph winds occurring 6 hours per day.
To put this in perspective, 30 kWh is less than 5% of the power consumed each month by the average household. Overall, the payback from a single, roof mounted turbine in tangible financial terms leaves a lot to be desired; especially in light of the fact that unlike solar, there is no Federal tax credit for residential wind power.
But anyone thinking about installing a rooftop turbine(s) is probably aware of this already. The rooftop wind enthusiast is not motivated by financial relief, but rather the intangible rewards of pride of ownership, walking the walk, or simple satisfaction as a hobbyist.
Motivation aside, it doesn’t make sense on any level to proceed with a wind powered project unless the three following requirements are met:
1. Higher than average cost per kWh. The more you pay per kWh for electricity, the more economical wind power becomes. A rule of thumb in the wind turbine industry states a residential wind powered system shouldn’t be considered unless you pay $0.10 or more per kWh for electricity.
The easiest way to determine your cost per kWh is divide the current monthly balance on your electric bill by kWh usage (also plainly stated on your bill).
2. Building codes. Visit your building department to find out if there are any zoning restrictions for roof top turbines. Don’t build your rooftop system first and ask questions later – only to be told it violates zoning laws and must come down.
3. Minimum wind speed. Wind speed of 7 mph, or 3 m/s (meters per second) is the start up speed for just about every wind turbine. However, in order to get any “juice” out of the turbine, minimum wind speeds of 10-12 mph for 6 hours per day are necessary.
Although wind speed charts for the United States and Canada are available to help site larger turbines, they’re of little use for rooftop systems because the data is collected at a minimum altitude of 30 meters (98.4 feet).
However, you can get a good idea of the wind speed at proposed turbine locations by purchasing an anemometer (wind speed meter) for around $150. The kit comes with a rooftop sensor, 60′ of cable and mounting hardware for the read out display. These are not data logging meters, so you’ll have to keep notes on your observations.
If you’re really serious about wind speed data collection, you can purchase a data logging anemometer kit with tracking software for $400.
Depending on where you live, wind speeds generally fluctuate with the seasons. Readings taken during the hot summer months of July and August, when you’re begging for a breeze, are not usually a reliable indicator of average yearly wind speed.
Also, rooftop turbines located at the edge of a long flat roof experience much more wind than those located on roof peaks.
If, after a month or two of collecting data you determine there just isn’t enough wind for a rooftop wind turbine, you can always resell the anemometer and turn your attention towards solar.
