A different water wheel design? Answered
I posted this idea on the makezine forums recently and got 1 answer but it seems I did not explain what I meant too well so I thought I would try here to see what you think.
See the diagram at http://www.nelliott.co.uk/maker/water-wheel.jpg
Would this produce more power than a conventional water wheel?
My theory is as follows:
In the case of a normal wheel each bucket/segment when full of water has the turning power equal to weight of water x length of horizontal line such as the yellow one in the diagram.
That is it's weight exerts a force to turn the wheel according to it's horizontal distance from the centre of the wheel.
If instead of the normal wheel the 3 blue circles represent 3 sprockets.There would be a whole series of buckets attached to the red lines ( which represent a chain ).Water would pour into the buckets as shown, so it would simply propel the buckets vertically down.The turning power of each one of these would be equal to to weight of water x radius of large wheel. So each would have the turning power of the best one such as the line from H to the center of the wheel.
As far as I can see this would mean a large increase in torque over conventional which I hope would easily offset the losses due to the chain drive.
What do you think?
