Tim pls see the Money-Fuel Tree story, it explains how a minimal outlay of conventional funding can be "Grown" and replicated in further Money-fuel trees, with no further need of conventional funding. I can testify as an Engineer with Chartered experience if you like, there are no rare materials, my business throughout life has been Engineering, of course I have always had to pay attention to all costs, as to whether or not something is viable.

It is stupendously viable, the most viable project ever, the returns are infinite, literally infinite.
