Wouldn’t this be safer for birds, too?

The system will have an average power of 3kW. Assuming a production factor of 25% the nameplate power will be around 12 kW. It is difficult to estimate the size of the corkscrew tower, but I guess it will be at least 30 meters high. On a mast of that size you could easily put a conventional wind turbine of 200 kW nameplate power.

Yes, I DO know the difference.
It was simple mistake, predicated by the information provided in the article:

“projected to generate 25,000 kilowatt hours of electricity per year”

Any new articles on VAWT systems coming up???

3kW per hour?! I didn’t know it had a ramp up speed!

A kW is a measure of instantaneous power, literally Joules per second, or volts multiplied by amps

A kWh is a measure of total power used – if something uses 3kW for an hour, it uses 3kWh of electricity. I think this is what you mean?

kW/h (kilowatt per hour) is not very common, but you could measure how fast a power plant starts generating using such a metric. (i.e. “This plant has a ramp up speed of 3kW per hour”).

Could you explain what you mean a bit more?

Ya I understand that this project isn’t going HUGH dent and isn’t the point of the project.
But this thing only produces 3Kw per hour.

Conservation of energy says no. Perpetual motion machines don’t exist… as energy is always lost due to less than 100% efficiency energy transfer EVERYTHING has.

So no, putting a fan to blow a wind turbine can generate energy, but it will generate less energy than you input into the system. It’s like the idea of putting a solar cell under a lightbulb – it doesn’t work.

In the best theoretical case scenario, you can break even: P(input) = P(output)

But in reality: P(input) > P(output)

im thinking of putting a biggest fan i can get and put it on the roof facing my wind turbine since the wind doesnt blow all the time but this is all in my head..will it work??

can we harness an energy from electric fan wind?
