perfect bird-slicing machine

This looks like it was built out of the parts of an old jet engine.

@FatFred2U lol?

First of all, I know how turbines work, thank you.

There is no such thing as kw/h!

Either you list the generation capacity, which is measured in W (which btw indicates a measure of power per time unit, fyi, W = Joules/second)

OR you list the amount of energy it can produce during an amount of time, such as kWh/month (which is also a normal metric for wind turbines, considering the average amount of wind, circumstances, etc)

(k)W IS an indication of momentary power generation.

@TheRealXesc A wind turbine does not accumulate energy, it converts it. The battery bank connected to the turbine is where the output of the turbine may be accumulated (stored). Expressing the output of the turbine without a time constant is nothing more than useless trivia that describes a momentary amount of energy. The load is constant (would you buy a lightbulb that only illuminated for a split second at a time), so average output/time ( or kW/h) is appropriate for a generator.

Why can't people get simple units right? 3Kw/h is a unit that doesnt make sense.

@suawekm yes i can count the blades....\:) if you press the stop button ...or you forgot how to click on the mouse ?

[electrodacus]

If it relay starts at 0.4m/s is useless since there is not much energy at that wind speed.

From 3 to 4m/s it make sense to start producing power and stop at about 16 to 18m/s most wind turbine have the power specified at 12m/s in your case probably 3KW not KW/h that is energy and not power.

Having multiple blades is for sure not efficient.

Having a wind turbine that starts at 0.4m/s will only give you less than 1% more energy than one that starts at 3m/s in most locations.

[leovideolog]

Why has it got so many blades? That may be good for torque generation but the most efficient for power generation is two or three blades.

[TheRealXesc]

But the title's spec is wrong - kw/h (kwh) is the accumulated amount of energy in a specified amount of time, in this case, an hour.

The specs should be listed as Watt (or kilowatt), so, 3 KW or 3000 Watt (and not 3 Kw/h)

@steban629 no, about 0,9 mph

1 m/s = 2.25 mph

explained:

1m = 1/1600 mile (1 mile = 1600 meters)

1s = 1/3600 hour (1 hour = 60 Minutes = 60*60 seconds = 3600 seconds)

so

1 m/s = (1/1600) / (1/3600) = 0,000625 / 0,000277 = 2,25 mph
