Vertical Axis Pinwheel

 Like a wind turbine, but smaller

There are a number of types of wind turbines for power generation which can use wind from any direction.

Make a scaled down one, for use as a child's toy.

Sainsburys: Vertical Axis Pinwheel http://www.quietrev...n.co.uk/sainsburys/
If this is what you mean (turbines that rotate about an axis that lies on the vertical) then they have these at my local Sainsburys. [zen_tom, May 27 2009]

       Could you link to what you are talking baout please? I googled but couldn't find anything. I put in your idea title and this idea was the first on the list.

       ... and this would be better than the gazillion vertical (and for that, any direction) axis wind kids' toys how?

       I'm thinking that a toy-sized version of any type of windmill, including a cup anemometer, is fairly obvious. This is just a "make it smaller" suggestion. [ ]

       [+] I like the idea, wouldn't have thought of it myself, and have never seen vertical turbines as a kids toy before. If I were a geek with kids, that's what I'd get them!

       zeno, search for "vertical axis turbine" and you'll see the type of machine that I want to shrink down to the size of a kid's pinwheel.   

       loonquawl, regular kids' pinwheels are *all* horizontal axis turbines. They only spin if the wind is coming from in front or behind. If the wind is from the side, they don't spin.   

       baconbrain, I guess it is just a "make it smaller" idea... but there's there's nothing in the rules against it :) ... if it were obvious, someone would have invented it already :)

       I thought those toys came in all different shapes and forms but you seem to have found a new one.

       // regular kids' pinwheels are *all* horizontal axis turbines. // They are, if held horizontal. If held vertical, thanks to the cup-like aspect of the wings, they work too.
