specific reference - Which research papers are referred to for the toy mentioned in the Arvind Gupta's TED Talk video?


I saw a TED Talk. You can watch it here on Youtube for your convenience.


At 07:17, he introduces a toy made with a pencil on which, a few notches are present; and on rubbing them with something, a fan attached to it rotates.(See transcript at TED if you are unable to watch it.)


And it is funny how he makes fun of LHC -



And you don't need the three billion-dollar Hadron Collider for doing this.



He mentions, it is a 100 year old toy, six major research papers, and one by little Feynman!


I tried to find any reference to the research papers. Considering that he mentions they are major, I had hopes I will find something on internet but I didn't find anything.



I have the following questions:



  1. What exactly is the toy called?

  2. Which research papers is he talking about? I mean, any reference to them? I really want to read them...

Can't guarantee these are the exact six he means! The same concept is being applied or suggested for micro and nano machines. For example "The rotation of the added molecule would then resemble that of a well-known children's toy in which a propellor rotates at the end of a rubbed notched stick." A.M. Stoneham The challenges of nanostructures for theory

Maybe the mention of Feynman is just Feynman's Ratchet
