So we built this piece of second grade work. this is my handywork and connected this to motorcycle batteries and ran some tests. it looked like it worked. so ukrainian engineers took the design and they built this and it looked like it would work. so then they took their own design and made it better and used a 3-d printer and made it resistant so there s only one way to put it together. and with crossed our fingers and took a $100,000 piece of equipment that the hus shipped over and plugged in this battery system to it. it didn t blow up. and then we had the ability to turn on the clue for training, to run it for eight to ten hours as a stand alone. and within 96 hours of us prototyping this first batteries, units that had been keeping their clues and missiles in storage were out hunting
