What does HXU stand for?

The neighborhood will be constructed on a series of ponds utilizing geothermal systems consisting of a stainless steel plate system that includes Slim Jim heat exchange units, ClimateMaster high-efficiency water source heat pumps and utilizing glycol for the heat transfer fluid.

It says it can generate large amounts of electricity by adding two propane heat exchange units to chimney stacks, thereby not only saving carbon dioxide emissions on a massive industrial scale, world-wide, from wasted heat, but also reducing the emission of harmful trace elements, such as cadmium into the atmosphere.

Problems to watch for are general abuse, bad crash repairs and poor maintenance (go for cars with service histories), dodgy, cheap left-handdrive models, worn engine heat exchange units (possibly disconnected to stop fumes filling the car), worn clutches, seized brakes, bad oil leaks and a lack of regular, hard use causing the engine cylinder bores to wear prematurely.
