Interesting.
But I'd prefer the bicycle siren.
Wouldn't that be a blast?
Wish I could spin our 2t22 with a bicycle. Wonder how high a frequency I could attain?
What % of one-horsepower can a human generate?

That thing looks pretty sturdy. Nice gearbox I imagine if I had a stator and chopper laying around I would make something like that.

LionKing had a profile on the old siren board if I remember right, he posted the picture of the prototype there.

Yes. That would be fun to power with a bicycle.
My wife is going to write them, in Chinese, to see if we can buy just the
gearbox on up and how much they would charge.
13-hp seems too much power.

A nice, DC-powered siren is still the best way to go.

Rob, I remember hearing that the average man produces around a third of a horsepower, at peak.

Thanks, Peter.
So four Chinamen pedalling their bicycle siren would produce only 1 hp?

Many parts of China have a problem getting electricity. But gas and diesel are everywhere.
So this direct drive engine does make sense.
Too bad they need the 90-degree gearbox.
How much power is lost through that?

1/3 = .33

4 x .33 = 1.32 = 1 & 1/3 HP

You are forgetting to calculate the Chinaman factor!

Would you care to explain that comment Mr Gift? My mom's father was born and raised in China (making me 1/4 Chinese) and I am curious to know what this all-encompassing "Chinaman factor" term means and how it therefore relates to me and anyone else of Chinese descent.

This was meant as humor.
My wife is Chinese.
Compared to caucasians, Chinese are usually smaller in height and weight.
Except her son, 19, who is almost 6'2" and growing.
