Without describing the problems you mention, we may as well be barefoot and pregnant on Fairy Tale Farm. Please describe this hopelessness in front of the people. We hesitate to describe our system until it is up and running and we can simultaneously defend it in three dimensions. We are not rushed. Our system, while labor-intensive, certainly does not need to be in a hurry until Spring 2018.
