In fact I would even argue the cost per barrel could even by closer to $50 or even higher. The major problem with these machines like you say is just getting them to run consistently. And so far they cannot even do that with what they describe as optimal, purchased plastic and lots of purchased HTF.
with mgmt's intent to sell prox is thinking all potential buyers will move in lockstep they don't and they won't even more realistic is they'll have data from many sources that can't be impeached including the national co. noted via mgmt's last update on 7.1.14
personally i suspect the first round of sales will be done at a discount to what future prox sold will be
(it's an emerging tech with the only publicly traded co. trying to get their foot in the initial doors)
i also believe after the first 10 to 12 are sold ..
prox will be tweaked for those buyers who don't need the beast's size (flagship)
interesting to note that executive summary used 600 sites
for those keeping score, it once was claimed to be an $80K processor (that's only 1% of the now touted $8M based on Madison county "DD"....100 times greater price tag now if one uses The Memos from Madison County as the new metric)......
great post about keeping it "real"......worthy of its sticky status....
