I'm sure Gloria will dig out the history of the Pelton wheel. The one shown is a double row of cups which are driven by jets of water. The shape of the cups suggests there is some element of axial impeller action to increase the overall efficiency, I seem to remember that some designs had a separate axial to take advantage of the water flow.

Yes, that's the first part of the question, it's a Pelton Wheel. Well done Gloria, but what about the inspiration for it?

I had no idea until I looked it up but Mr Pelton turned a hose on a cow to stop her disturbing his gold panning operations. The water hit her cup shaped nostrils and threw her head back which inspired him to design the turbine. :smile:

Exactly right Wendy and the ironic thing is that if you look at the Wiki page Gloria put up as an answer and skim down to the sources you'll find a link to the original news report on the story. 'The cow that assisted science'.

I would have thought that a jet of water up your nose or any other orifice would make you throw your head back. Sounds a bit like he's trying to create another Newton (Isaac) myth. :biggrin2:

Kev was first I think. Yes, a hand operated vacuum cleaner. From what I understand, not very practical!

Right. Have a look at THIS article on northern and eastern France’s Le Père Fouettard (Father Whipper), a sort of anti-Santa. And no, I had never come across this weird custom either.
Next for shaving?
