If yi would have to do more reading to understand the lattice stuff, it seems reasonable though.

As far as usefulness, the idea I had was you could layer a substrate to dissipate the heat really well. My limited understanding is 85% of the heat jumps the wires somehow and is absorbed by the substrate, which could be engineered arbitrarily. This is important because cnt are very good electrical conductors so you could pair them with a good head absorbing substance and achieve separation of heat and current in ways we have not seen before, which one could speculate as a way to restart moores law progression of speed.
