The answer to the cost question is I don't know.

The questions are,
1. How screening, washing and drying will be integrated into the low-cost production process in the production cell?
2. Does it require additional equipment to do so?
3. Will the further process equipment as easy as the production cell that can be assembled onsite of customers?
4. If the VFD is a further process to purify the produced graphene to single-layer, will VFD be assembled onsite of customers or make available to customers? If not, that means you still need a production facility to do it. Then the whole point that the production cell is easy to be assembled onsite of customers is pretty useless.
