OMG they are back
The old adds back in the day claimed to pull in over 150 CFM, which a car does at idle.
I tried it back in the day. I bought it online at a boating supply house, because all these things are, are galley fans. I paid $20 plus some wiring. When it didn't work, I sold it on eBay for $200
