So Greenblatt had the idea that he would find a customer who would pay in advance to buy the parts. They would build machines and deliver them; with profits from those parts, they would then be able to buy parts for a few more machines, sell those and then buy parts for a larger number of machines, and so on. The other people in the group thought that this couldn't possibly work.
