We have some ideas for further modification that we may or may not implement. For starters, we will probably connect a hose to the heater core output. This will eliminate the burbling, trickling sound that is hard on one's bladder, as well as make it easier to drain. The ArcticAir units have a valve inside that you turn to redirect the output to an external hose so that you can drain the cooler out the window onto the flight line without wrestling it through the door. Another option would be a drain plug on the bottom, which is already on many models of coolers. We also are considering a vent system, so that the lid could remain closed while still allowing air to circulate. The ArcticAir units have a louver vent on one side for this purpose. A third modification would be some way to redirect the airflow. ArcticAir units have adjustable flaps over the fans, which could work, or some have a duct hose assembly to redirect the airflow where it is needed. A fourth, and painfully obvious, step would be to enclose all the wiring inside the lid or in a project box to make it look neater. However, for the time being, the zip ties are plenty for us. Also, we may try using Blue Ice-type ice packs, so that it would be reusable and not waste water.
This being a Go Green contest, I should put in a spiel about why you would bother with this. The main purpose is to make it more comfortable to drive a zero-emissions electric truck in Kansas in August. This runs off any 12V power source that can shove out 3 amps, so it can be used in other areas that need cooled, such as a hot workshop. Also, the ice lasts for hours when it's not running, and you can leave it on while you run into the store. The only disadvantage is that you could say it wastes water in the form of ice, but you can empty it out on your garden or lawn. It uses only ice water for cooling, which is about as non-toxic and environmentally friendly as you can get, and it kept a hose, a cooler, and a heater core out of a landfill. In other words, it uses environmentally friendly power to run environmentally friendly coolant through recycled parts in a zero-emissions vehicle. Can you get greener than that? I mean, this is #008000 at its best! Just make sure to recycle batteries.
