Cooling with a heat pump is a pretty neat idea. I need to break out the thermodynamics book though. If Ford will only run it for 10 seconds or so, that probably means that it's not that efficient. But if you look at something like drag racing, it would be cool to have a system where you could temporarily use the AC to freeze your reservoir, switch it off so there's no power draw, and then have 20-40-60 seconds of super low IATs for your pass. An extension of that... use a Prius electric AC compressor dedicated to the reservoir and remote mount all that stuff. And then... leave room in the reservoir for drinks!
