Outer space is the coolest, most mysterious thing I will ever know in my life. Second to none, the closest thing I could experience to a trip into outer space is the depths of the ocean. In a sense, the two are very similar – diving deep into the ocean places a ton of pressure of the human body, and quickly returning to the surface of the ocean after being hundreds of feet below the surface can easily kill you. The same can be said about venturing into space, as the extreme cold and pressure variation would quickly turn you into a cup of human tissue once the pressure got to you. When I go scuba diving, I’m very careful about slowly returning to the surface of the ocean, which can be agonizing since the scuba suit won’t keep you from feeling extremely cold in the ocean waters! Thankfully, the boat I used to head out into the ocean for my dives has an excellent little cabin below deck that is equipped with a set of electric space heaters. Typically not the safest thing to have indoors, especially aboard a ship, these space heaters work wonders for rapidly thawing me out after several hours deep in the ocean. Plus, these space heaters work incredibly well for rapidly drying out my scuba suit for the following day’s return to the ocean depths. All this happens without sacrificing the indoor air quality of my boat’s cabin too, as the space heaters work through convection but cannot offset the humidity caused by being out in the ocean for days at a time! If you haven’t tried it, I can’t tell you enough how humbling it is to be in the depths of the ocean. It’s the closest thing most of us will know to being an astronaut in space!
