Hmmmmmm.......maybe even the problem could be a benefit to us? If D-20 should be formulated at the user, each user would need a NPU.....and if you any spend 70,000 USD per month on fuel, you would probably not mind investing in a NPU if it pays off in the long run......or possibly ECOS should make a discount NPU/Mini NPU which could be affordable to the farmers? Who says it needs to make xx thousand gallons per hour?
I know I'm dreaming, but why not?
