JBI seems to have designed everything itself. At least that is my impression. I realize that thye ae a small shop and cnanot afford a large engineering firm (and neither would a large engineering firm really want to work with JBI..), but I have to think that in the long run it is not a cost-effective way to operate. I would have thought that beyond the prototype, it would have been better to outsource the engineering and focus on marketing and sales (and finding feedstock, LOL, as Procurement seems to be an expensive endeavor).
