They are apparently 'belly-up' for civilian use.
There is still the large military licensee . A fully charged EEStor capacitor probably makes an excellent explosive device, but they have never owned-up to that possibility. From: Esa Ruoho Uhh, I guess my mind lapsed into oblivion at some point in time and I forgot to pay any attention to EEStor. Are they alive, are they going to produce something, etc? Some facebook numpties (who have a habit of quoting Rockefeller) started going off about EEStor being a nonexisting company with a nonexisting product. I'll trust VO opinion over FB randomquoters any time, so have at it, was it real, is it real, etc.
