What is it one of them there kiddiees linear motor demo kits? Idel for launching things that break ornaments. Brian

How does that work?

"selectively switches-on between the mating surfaces of each of the individual contacts, staying non-conductive between adjacent contacts" Are they saying you put it on the commutator of a motor and it conducts from brush to commutator but not commutator to next contact of commutator? How does it know?

I think this

that it conducts very well when it's thin, but insulates when thicker. So it improves a contact which was touching or supposed to be touching, but doesn't conduct a long way away, like to the next contact. Clever that stuff. Could it be described as intelligent? And how does it do it?

Do they use it in a lot of equipment? Sounds like it would be perfect in motors. Could I put some in my power drill that sparks a lot?

Where do I buy some in the UK? Ebay doesn't have any, Amazon is out of stock until further notice, Google shopping gives no results.

LOL! Hilarious!

Where else would Gremlin think the energy comes from? Amazing.

Another example of Gremlin presenting himself as a fraud.
