Wind Energy Voice

I’m in the process of building my first wind turbine and was curious if running it without a load (ie. battery bank) would be harmful to the generators? I’m using a 260VDC 5A permanent magnet treadmill motor as the generator. I’m about ready to put up my tower and wasn’t sure if I can go ahead and get it all assembled and put up and then add the battery bank as soon as I can get the batteries. This way I could also see how well it’s going to perform on the tower. It’s a 60′ lattice tower and will be hinged at the bottom but still will be a bit of a pain to lower and raise a lot. I’m really excited about getting this up and running but don’t want to damage anything before I even get started.

Also I’ve heard of people using old electric baseboard heaters as a load dump when the bank gets fully charged. I’m having some trouble locating any of these around here and was wondering if anyone would have any other suggestions on something I could use as a dump? Thanks for all your time.

You will wear the bearings a bit, but there
will be no damage to the generator from
turning without load.

How do you intend to prevent overspeed in
a high wind though?

As to the load bank, if its only 5A., the nichrome
wire units from an old toaster or two would do it.
(Leave em on the mica in free air.)

What is keeping wind power from widespread use and when is it expected to be easily accessible to the general public?

The last time you had a choice to pick your source of electric power, you may have had a choice for wind power produced electricity at about a 1-1.5 cent per Kw of electricity premium.Otherwise called "green", it is on the grid. It is generally more expensive than traditional power but it is improving.Estimates are that wind power could produce 20-30% of the grid power by 2030. The Bush years saw a reduction or elimination of tax credits for green power. The Obama years may see an incentive which would raise the expectations because of tax relief or incentives. After all, Connie Rice had a vested interest in big oil but Obama doesn’t seem to.

This video is taken when windmax wind generator is on the 5.9 feet test pole and the wind is 10 mph according to weather channel. the blades performs extremely well and spinning very fast at low noise. imagine much greater performance if this wind generator is at 26 feet high !! The blade diameter is 1.4 meter or 4.9 feet. While at the same wind speed, the old style wind turbine with mechanical furling with 8.2 feet diameter blades doesn’t perform, the blades barely moved. Instead, the wind generator head is turning around, which is very bad. the blades for these old style wind turbines have poor design and such low efficiency, it can’t capture the power in the wind even with the larger swept area, that is the myth about these blades with larger swept area, most people would think that the blades with larger swept area always performs better than blades with smaller swept area, that is totally untrue, if the blades with larger swept area won’t operate/spin efficiently as shorter blades, it can’t capture the power in the wind, and it won’t output energy !!

The energy output is the energy converted by the turbine blades into mechanical energy, the turbine blades need to spin in order to convert all the wind’s power to mechanical power. The low effciency turbine blades don’t spin or barely move, there is no energy output !!!

Rated energy output of the old style wind turbines with mechnical furling and low efficiency blades is very deceiving because the blades have such low efficiency that the larger swept area output little energy, some of the old style wind turbines with mechnical furling and low efficiency claim 1000w, 2000w or more, the actual output is much lower.

Wind power is one of the fastest growing forms of alternative energy in the world. More and more, wind power mills are seen in the countryside, in large wind farms and for the most part, away from city life. But a new form of wind power is now designed to work in an urban environment. VOA producer Zulima Palacio has the story. Mill Arcega narrates.

Can anyone show me how to build a home made wind generator. Or show me the site to it. Thanks and have a nice day.

Type wind power on Yahoo search.
Other related topics, alternative energy, free enery, windmill farms.

My suggestion, get a old electric fan or motor and rewire it to produce
electricty. You other parts like fan blades gears, battery, battery charger.
voltage converter etc.

Let me know when you have one working.

Has anyone seen this on Maui? We plan to move there and want to reduce our dependence on the grid. The wind speed of the Hawaiian islands is approx. 10% higher than the avg. on the mainland.

Any feedback is appreciated.

You will need a large piece of land or acreage if you plan on installing a wind turbine as most jurisdictions have restrictions. However, Hawaii may be the exception. I inquired about one on my property a while ago and the installation cost was over $20,000, with a 5-7 year payback. Below is an article I found that you might find interesting. Good luck!

Advantages : The power they generate is basically free.

Disadvantages: They don’t work when it’s not windy.
They are large and generally unattractive
There needs to be several of them at a given site
to make a meaningful amount of power.
