Idealism-induced myopia combined with the current "green tech" fad is breeding some truly bad business ideas. This is one of them.
Seriously, I'm supposed to wash my entire car with a quart-sized seventeen-dollar bottle of mostly-water in order to save a few gallons of tap water? There's a small number of people out there who are dumb enough to pay for anything if they think it's "helping the environment" (at least until the next fad comes along to displace the green-panic fad of the moment) but the market seems really very limited, both in extent and in duration.
Revenue, customers, and.. a logo?
They do have 2 out of the 3, maybe it's like the ol' "good/cheap/fast, pick any two" thing.
