One processor costs less than $1 million and theoretically will produce more than $6 million in annual revenue.
More or less it goes, 1+6+36+216=259 processors.
So in theory, after three years 259 processors could be paid for by one processor commencing operations, assuming the processors successfully operate as company has projected.
The recently raised funds should cover general overhead for the next two quarters and also allow at least 6 procesors to be constructed. Six processors in operation makes the company easily self sustaining.
