Wind Powered Generator Prices

A non-shrouded VAWT can lose as much as 95% of its energy to structural wind loading and anti-rotational wind loading. The non-shrouded VAWT is estimated to be only 5% efficient per wind sweep area. Thus, the price that you pay for it in wind loading per actual watt hours earned can be very high.

A correctly shrouded VAWT can lose as much as 90% of its energy to structural wind loading and anti-rotational wind loading. The correctly shrouded VAWT is estimated to be only 10% efficient per wind sweep area. Thus, the price that you pay for it in wind loading per actual watt hours earned can be very high.

A three bladed aerofoil lifting wind turbine can lose as much as 85% of its energy to structural wind loading and anti-rotational wind loading. In addition to that, it can lose as much as 96% of its potential for wind load convertible energy by the wide open spacing between the blades. In addition to that, it can lose as much as 70% of its energy to aerodynamic non-alignment ( see aerodynamic characteristics from sandia laboratories ), which is so variable that we will ignore it for now. Being generous, the three bladed aerofoil is estimated to be only 1.2% efficient per wind sweep area. Thus, the price that you pay for it in wind loading per actual watt hours earned can be even higher than the VAWT.

Our Wind Powered Generators, with our version of "flat plate technology" are estimated to be less than 40% efficient per wind sweep area. Even with ours, there is loss due to structural wind loading and some anti-rotational wind loading.

When you purchase, and the price looks good, THINK about what you are getting.

If we do not consider the supporting structure, and just the design of the blades themselves:

Non shrouded VAWT = approximately 5% efficient. NO !

Correctly shrouded VAWT = approximately 10% efficient. NO !

3 bladed aerofoil lifting wind turbine = approximately 1.2% efficient. NO !

Our Wind Powered Generators = approximately 39.65% efficient. YES !



We have used the "~" sign occationally. Some of our international viewers may have been confused by this symbol. It means that a number is approximate. "~" means "approximately", as in "~1" should be read as "appoximately 1".



Of course these are estimates. Different manufacturers will have different percent efficiencies. Even our different models have different efficiencies. These are estimates, but it is something that you should think about. Know what you are buying. Think before you purchase.

We have stopped publishing those.

We have occationally found some very similar (almost exactly the same) of these showing up on our competitors' pages. Sometimes, we are not saying who, but their product has not changed and yet their claims have changed and now they are saying that they produce (almost the same) the output that we produce. Of course the claim is slightly different, we guess to cover their butts legally, but their claims have changed so radically into line with our's that we have stopped publishing these. Do not call and ask for these. Do not email and ask for these. You will be told "no." Unless you have already actually purchased a Wind Powered Generator from us, then we really do not know if we are talking to another competitor. Our answers to seemingly simple, seemingly innocent, emails and/or phone calls have often shown up on someone else's web page as a claim that they do the same. No problem. We are being more careful in giving out information.

We have found a potential for a couple of types of customers; First type of potential customer are those that actually read, think, and buy. And second are those that ask for more and more and more technical information, and then they put up a web page imitating us and trying to sell those silly, illogical, waste-of-space, three bladed wind turbines. We already supply MULTITUDES of information on our web pages. If you are not sure, then read it all.

Think! You do not need a chart or a graph to tell you that our Wind Powered Generators are extraordinarily more efficient per blade sweep area than those silly, illogical, waste-of-space, three bladed wind turbines.

Estimating a standard U.S. homeowner's energy needs:

Multiply the current (amps) capacity of the incomming breaker box (commonly 100amp or 200amp or 300amp) by 240volts to get the maximum load capacity (wattage) of the system. Then divide this by 3 to get the average all-electric house needs. For a house with a combination of electric and gas, subtract 10% to 30% from that number. If they have teenagers, the energy needs could be radically higher. These are averages, remember that AFTER a homeowner's energy bills decrease (by having their own partial energy source) they might dramatically increase their energy use.

Wattage and watt/hours are seriously different. They should NOT be confused as being the same. Wattage is amps x volts. Watt Hours is amps x volts x HOURS USED. They are seriously different. If the customer tells you watt hours, that is NOT watts. A tiny little one watt source, if used for 10,000 hours equals 10,000 watt-hours. A 10,000 watt source used for one hour is 10,000 watt-hours. They are very different. Do NOT let our competition fool you by their advertising "watt hours," as that is totally irrelevant (by itself) to the customer's needs.

ALSO there is NO guarantee as to the watt hours that a customer will get. God Almighty controls the wind and if He decides to send no wind then there will be no watt hours available. No human can guarantee the watt hours available to the customer.

ALSO there is NO guarantee as to the percent of billing reduction from using wind power. Again, God Almighty controls the wind and if He decides to send no wind then there will be no watt hours available, thus NO billing reduction due to generated electric. No human can guarantee the billing reduction available to the customer.

If an advertiser states a definite future percentage billing reduction, then they are lying. If they give examples of other people's billing reductions, that is totally irrelevant to anyone else's billing. It cannot be humanly guaranteed.

We shall suffer that which is common unto man. It has been common for the wind to blow and for the sun to shine. But we cannnot guarantee either. We do not guarantee these to do anything at all.

Our Prices, Wind Powered Generator Prices

You need TWO numbers:

(1) Multiply the AVERAGE yearly wind speed by 1.538 ( or x 100/65 )

(2) Multiply the AVERAGE yearly wind speed by 1.25 ( or x 100/80 )

That gives you the range of the rated wind velocity that is used to estimate the maximum rated output.

Generally, the yearly average wind speed is 65% to 80% of the maximum estimated commonly usable wind speed.

This can be very easy. Follow the steps outlined here and then chose the Wind Powered Generator model that you need.

Calculations:

(1st number that you need)

( 6.0 m/s ) x ( 1.538 ) = 9.228 or we can round that to 9.2 m/s
Thus the first number is "9.2 m/s"
6.0 m/s is about 65% of 9.2 m/s or 20.6 mph.

(2nd number that you need)

( 6.0 m/s ) x ( 1.25 ) = 7.5 m/s
Thus the second number is "7.5 m/s"
6.0 m/s is about 80% of 7.5 m/s or 16.7 mph.

Therefore the rated wind speed in meters per second is from from 7.5 to 9.2 m/s ,

Or if you started with miles per hour, then it would be from 16.7 to 20.6 mph.

This energy conversion range can vary due to the density of the air passing through and other factors. If the air is dry and hot, the density of the air could be low and thus the energy conversion could be low. If the air is cold and wet, then the density of the air could be high and thus the energy conversion could be high. If it is raining with lots of volume then the energy conversion could be even higher. The density of the air also has to do with elevation, or height above sea level.

Use the following table. It is there for you.

Look on the next table. In the left column chose the kilowatts that you need. In the right columns chose the wind speed that is closest to your required rating.
