Re: [EVDL] Firefly's press release

I actually got to meet Kurt Kelly, the designer behind the Firefly
battery, and a David (forgot last name, engineer there) at a battery
conference this summer - it sounds like this truck battery, or maybe the
next battery after it, has just one electrode (forget which) replaced by
their graphite system, and they hope to get both replaced in a following
iteration. These truck batteries don't seem quite designed for ev use yet,
unfortunately. It also sounded like they are working on a version of their
battery for hybrid applications, though we pure ev'ers are of course waiting
for a high energy rather than a high power battery.
Ironically enough, Kurt Kelly originally studied something like
ethnobiology to work with oil exploration to discover where lots of (little
or otherwise) animals died to better locate good oil drilling sites, but
likely due to Hubbert's (continental US) oil peak, predicted in 1950s and
verified in 1972 or something, oil drilling business took a nosedive and Mr.
Kelly ended up at Caterpillar (though I'm not exactly sure doing what, until
this came along).

my .8 cents worth of knowledge on this subject,

Seth Myers
