Jared developed a design for a shelter made out of two polyiso panels that has just enough space for sleeping and nothing more. A shelter made out of two 48x96 inch walls and a 48x96 inch floor of some other material produces an equilateral prism with cut ends that is 41 inches high - larger in every dimension than most single person tents.
Obviously polyiso is a bad material for the floor, so Jared's next step is to look into semi-rigid plastic sheets. A tarp with wood boards at each end is another option or even a sheet of plywood. His plan is to make it semi-folding, and install a small swamp cooler at one end and a furnace filter in the other.
It's been suggested it's best not to have a floor for the Playa, as the ground acts as a heat sink.
