@DamienZshadow. It doesn't store any energy. The energy is coming continuously from slowing down the motion of the air relative to the ground. When the cart reaches its top speed, it will stay at that speed indefinitely (assuming that the wind keeps blowing at the same rate). In this respect it's...

Under the Yardstick, Faster than the Yardstick

Video demonstration and explanation of a cart that moves under the yardstick, faster than the yard stick.

coolaun said:

It's nice to see some more "under the ruler" machines appearing on YouTube. You need to check your calculations, though: if the ratio of outer to inner radii is 2.36, that will not make the cart move 2.36 times as fast as the yardstick. A hint: think of what will happen if you make the inner radi...

  Under the ruler 3: tilting the ruler
  
  Since some people say that I'm tilting the ruler to make the cart move right or left, a quick demonstration to show that this isn't the case.

  @UTJhn That's a very good idea. Unfortunately I don't have the elements to make a second identical cart: the cart was just made from bits and pieces I had around the house. Maybe I could find enough other bits and pieces to make a cart with the same dimensions.
