How long before they jump on this..?

This stuff is comprised of nano tubes.

Sounds an awful lot like Carbon Fiber ?

Would ,   planar-magnetic speakers ,   be the kind of use , in audio , for this kind of new material ?

Electrically conductive .

Very interesting prospects for this new material but as jond pointed out, half the members here will be diametrically opposed to it because of its connections to green energy. 

The only other new speaker driver material I know of is basalt (lava rock) that Revival Audio uses in its mid woofers and woofers. (akin to green energy as it's naturally occurring).

All the best,
Nonoise

It will be interesting to see how this ends up in the long run. There are many flashes in the pan but every once in a while something really innovative pops up.

The stuff is already available for sale at the company’s websites:

My best mate to you...

That does look really cool carpathian! However it's also describes as "green technology" so half the folks here will hate it. 🤣
