Looks like some #humans have invented something extraordinary. First take a look at the wire resistance for copper of 0.006" diameter...260 to 390 ohms per 1000ft or 1ohm per meter
http://hyperphysics.phy-astr.gsu.edu/hbase/Tables/wirega.html

Then look at the new material by dexmat.com:

150um/25.4=0.0059"
And it's conductivity is 10ohms per meter. So you need around 10 times the cross sectional area to match the conductivity of 35Ga copper wire. But let's look at the total mass....

1 meter of the #dexmat.com carbon #wire is 19mg, and for #copper, that is 142.9mg. not quite 10 times but not far. The material is fairly #equivalent and it's all carbon.

However, they gotta work on the #affordability. 0.5 meter of 35Ga strand is $75 bucks! They need to #industrialize the #bejisus out of the #process to make it worth anyone's time. But it's #carbon and it's real not like #graphene.

That $75 for 1.6ft. by comparison, you can buy 25ft of 18gauge copper wire for $6.23!, That's 15.6 times more or 49 cents for the 1 meter. The #carbon #wire costs 153 times more for same diameter and length, and 1530 times more for the same conductivity as copper.

If I were an investor, I would see this as having #1500x return on my investment once they really get cranking out miles of this stuff via subcontracts and other such #patent sharing business.
