Electricity can flow through graphene at high frequencies without energy loss

[Confounding]

This is huge. I didn't think it was possible to conduct electricity without energy loss.

Electrical signals transmitted at high frequencies lose none of their energy when passed through the 'wonder material' graphene, a study led by Plymouth University has shown. Discovered in 2004, graphene – which measures just an atom in thickness and is around 100 times stronger than steel – has been identified as having a range of potential uses across the engineering and health sectors. Now research has shown graphene out-performs any other known material, including superconductors, when carrying high-frequency electrical signals compared to direct current, essentially transmitting signals without any additional energy loss.

An atom wide? Sounds expensive as hell to produce. Something for the future for sure though.

It is, but hopefully not for long.

The Price Of Graphene

In several years, bulk graphene prices may drop below that of silicon, enabling graphene to enter all markets now dominated by silicon, such as computing, chip manufacturing, sensors, solar cells, etc. In the meantime, graphene will continue to be used for applications that other materials simply cannot support. For example, silicon cannot be integrated into future flexible smartphones, because silicon is brittle and will break upon bending. Graphene offers a competitive solution.

With out energy loss? That's impossible.

you can make a cheap graphene-like circuit by taking a piece of tape and sticking it to a piece of carbon, then pulling the tape off.

we've done it for shits and giggles in the lab and it actually works.

graphene is nothing but a very, very thin layer of carbon. it will become extremely cheap at some point. Only thing holding it back now is that it's relatively new, but that will change, as graphene rocks.

There are a lot of ways I can already think of to make it cheaply. Similar to how it's done with carbon nanotubes you could grow the circuits, or you could flock the material, or ?

Yeah, we'll be seeing a looooot more of graphene in the very near future....

Graphene has some properties that make it very interesting. I think it has some properties that may lead to anti-gravity. But that's me.

There are some very interesting things about how it affects our measurements of mass...
