Wooo, another great looking idea! I imagine I can pull the oil pump off the same engine I pulled that alternator off... Anyone know how fast oil pumps in car spin?
Also, I'll be on vacation till Wednesday so its not gonna get done real soon. If anyone has something laying around and wants to test it out that would be awesome!
I was also thinking... A closed system sounds a bit complicated with a high pressure pump. BUT, so you don't have to carry a ton of water, I was thinking of a semi closed system. Basically, you have the heating side and a condensing side. All the water gets collected in the condensing side after going through the turbine/pump/gerotor so you don't waste all that water (which should be distilled so there isn't build up). Now, you just dump the condensed water back to the heating side once its cooled down. You could do this manually or you could use a small cheap pump to do the same thing (windshield washer pump perhaps). You could have it run a few seconds before you start the car up. Simple and cheap! You could even throw an arduino on it with a temp sensor to automatically pump when it has cooled down if you wanted to automate it.
