I believe that EEStor is the only energy storage company with a tribute folk song.  I checked the Maxwell website and they are lacking an ultracapacitor jingle, having to settle for actually building and selling ultracaps.

James Schultz, Quaker songwriter, begins his song as an earnest paean to our favorite stealth energy firm.  The minstrel regales us with the tale of "DW," "CWN" and "IC" and the saga of permittivity and barium titanate purity.  Very few folk songs manage to fold in these terms save for the lost verse of Woody Guthrie's "This EESU is Your EESU."

Brother Jim's song continues with EEStor saving the planet with the miracle of energy storage.  Energy crisis averted.  Case closed.

But the song does have an alternate ending in which "DW" and "CWN" end up in a "penal colony" for evidently defrauding their investors.  The alternate ending is much more Guthrie-esque.

Meanwhile, in non-musical EEstor activity, we've had the "leaked" Dick Weir phone call courtesy of Paradigm Capital, the non-enthusiasm of non-investor Vinod Khosla, and the seeming non-enthusiasm of early EEStor investor Kleiner Perkins, allegedly not participating in a recent EEStor funding cycle.

Rock on, Brother Jim.
