17years - As far as funding production. I'm not sure it would be that difficult to fund. Machines are selling for $90,000, so a typical retail markup of 100% would mean $45,000 cost to produce. But this isn't typical -medication that is priced at $20/pill only costs the drug company pennies to produce - you are paying for the research - same here. Without knowing anything about Medizone's cost I would guess if these machines are priced at $90,000 it doesn't cost them more than $10,000 to produce - practically completely covered by a down payment.
