I was recently abducted by aliens in the middle of the night. I was sleeping soundly and I did not hear the UFO floating outside my window because I had my window air conditioning system running on high. When I woke up, I was in a cool white room with little alien creatures surrounding me. I sat up and looked around; The aliens were honestly friendly to me and they gave me a tour of their ship. I, being a heating and cooling professional, wanted to see how their heating and cooling systems worked in the UFO. The aliens took me to a massive, glowing A/C system. They let me take a look inside and I was amazed and a little confused on how the device worked. The air conditioning system had some odd green glowing liquid that they used to cool the air. The actual ductworks were clear tubes that were installed on the outside of the ceilings of the UFO. The odd green liquid was still visible in the air as it was blown by the air conditioning system into the ductworks and out the vents. It was incredible to see! Then I took a look at the furnace for the ship. The device was made out of stainless steel and inside, instead of using fire to heat the air. There was lava inside of it. The air would be pushed through the chamber with the lava in it, and then blown into the ductworks and out the vents. It was an easy yet incredible way to make a furnace. Once I returned home, I began inventing my own heating and cooling systems similar to the alien’s systems.
