Aside from the address, this is a scam because:
A) The variable cost of a chip comprised of photonic logic gates capable of performing SHA-256 calculations would far exceed $10k given the yield of the technology.
B) Photonic logic gates operating in the 400-450nm exist in labs right now. Diffusion is the leading defect present during manufacture, smaller wavelength only exacerbates the previous claim.
C) In non-inert gas bath systems (although CO2 has been used in some cases), it requires in place spinning of fiber glass "conduit". So either the system has to ship with a gas circulation system to keep gas density uniform or, again, they're using things that only exist in labs at this point.
I'm selling eye protection ware just so one could view the renderings once they become available.
