Supercapacitors made from it have an energy-storage capacity, or energy density, that is approaching the energy density of lead-acid batteries, while retaining the high power density - that is, rapid energy release - that is characteristic of supercapacitors.
"This new material combines the attributes of both electrical storage systems," said University of Texas team leader Rodney Ruoff. "We were rather stunned by its exceptional performance."

Hey if Eestor bought that technology, they might actually be able to deliver a product in a few years from now!

If Bill Gates could do it with DOS, why not.

Gates didn't
buy DOS:

Kildall was particularly annoyed when the University of Washington asked him, as a distinguished graduate, to attend their computer science program anniversary in 1992, but gave the keynote speech to Gates, a dropout from Harvard. In response he started writing his memoir, Computer Connections.[11] The memoir, which he distributed only to a few friends, expressed his frustration that people did not seem to value elegance in software,[14] and it said of Gates, "He is divisive. He is manipulative. He is a user. He has taken much from me and the industry." In an appendix he called DOS "plain and simple theft" because its first 26 system calls worked the same as CP/M's.

Huh, thanks. The movie "Pirates of Silicon Valley" gave me a completely different impression.

Perhaps EricF was thinking of
QDOS/86-DOS, which Microsoft first licensed, then bought outright before IBM released the PC.
I'm not sure I would call cloning system calls "plain and simple theft". The law tends to agree on that point. And I'm sure Microsoft doesn't much like it these days, since they're often on the receiving end. In fact, Microsoft's system calls are about the only thing you would want to copy from them.

i can see this being really useful - especially in pulsed IE fusion schemes. no mention yet of when production devices might be available though.
