Solar+Solar coolant heating hood?
Something I've been thinking about for the last few years...
If one was to take some thing (say, 1/4") aluminum tubing, attach it to the hood of the car, snaking up and down the entire hood (under the hood for aerodynamic sakes), paint top of hood black, tie in a few hoses and a small pump (connected to a solar panel) to the coolant system...
It seems like an easy enough task to accomplish. I've got my old Neon that's up for some experimentation! Summers here are plenty of sun and 90+ degree F heat. Cloudy days and winter could be less effective (or not at all).
Thoughts?
