Somebody can't do the math.

The usual journalistic nonsense.

" The water wheel produces one to two kilowatts of power and generates at least
24 kilowatt hours of sustainable green energy in a day "

I had a look at the page. 1 to 2 kilowatts is massively
overestimated. Without calculation I'd estimate it as
1 to 2W at most. From my experience it takes a few
liters a second at a dozend meter to get few hundred Watts.

Yes, as John said, someone can't do the math. It's not as if it's difficult either !

You'd need a flow of something like 50 litres/sec and a 2m drop to get 1 kW.
