I agree with the last two posts. If I remember correctly the worldwide market for these types of pumps is about $10 billion annually. If, over time, "our" pump captured 10% of that market and if, since it's protected tech, the margins were at least 20% you'd be talking about a lot of money.
The problem (IMO) is the same as it's always been---finding a buyer---and hopefully a buyer who "believes" and would aggressively push the tech. Z
