I was recently abducted by aliens in the middle of the night. I was sleeping soundly and I didn’t hear the UFO floating outside my window because I had my window air conditioner 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 very friendly to me and they gave me a tour around their ship. I, being an HVAC technician, wanted to see how their heating and cooling systems worked in the UFO. The aliens took me to a massive, glowing HVAC system. They let me take a look inside and I was amazed and a little confused on how the unit worked. The air conditioner had some strange blue glowing liquid that they used to cool the air. The actual air ducts were clear tubes that were installed on the outside of the ceilings of the UFO. The strange blue liquid was still visible in the air as it was blown by the air conditioner into the air ducts and out the vents. It was incredible to see! Then I took a look at the furnace system for the ship. The unit 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 air ducts and out the vents. It was really a simple yet incredible way to make a furnace. Once I returned home, I began inventing my own HVAC system similar to the alien’s system.
