What this guy invented operates on precisely the same principle as Quantum Tunneling Composite (QTC) - the physical principle of quantum tunneling, however, it is completely different transduction mechanism - in mathematical term: as different as exponential dependance (QTC) and linear functional dependance (Quantum-Pi), vertical motion vs. lateral motion, 2D vs. quasi-1D electrodes. Lots of differences, sufficient to have patents granted in the USA, Russia, Israel, .. and some 27 other countries. But, it is cheap, reliable and has multitude of uses, just as Mr H. Ruiz has correctly observed.

Quantum Tunnelling Composite (QTC) has been around since 1996, its primary use being sensors. It's cheap, reliable and has a multitude of uses. What this guy has "invented" may operate on a completely different principle but I doubt it.

Years Ago heard about Nanotubes & Graphene. Well, you know response, its old lubricant. Yet, it turns out, Old showing Up in New Places.

Heres article: http://www.technologyreview.com/computing/22503/?nlid=1957

Explaing how one single carbon atom can not be made to change power state. its one shot deal. how 5-50 Nm carbon bundle, when oxygenated, grows cylinders out of its side)W/Pics). finally, how this might be new tranistor material. except, cutting atoms apart ain't easy, so long, long way out. Yet heres device that use name, nanotube for sales. drashek
