Conceptualized by Nikolai Kardashev, a Russian astronomer, the Kardashev Scale is a way to determine how advanced a civilization is, based on the amount of energy the civilization consumes. Kardashev had initially made three categorizations, Type 1 is a planetary civilization which is able to store and use all the energy available on its own planet from its own star, Type 2 being a stellar civilization which is able to harness and utilize the energy of its entire star and a stellar system (a close group of stars) and Type 3, a galactic civilization which is capable of harvesting all the energy from across its own galaxy.
“Space is big. You just won’t believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it’s a long way down the road to the chemist’s, but that’s just peanuts to space.” – Douglas Adams. Now, try finding your parking spot. Lagrange points may be ideal for permanent space platforms.
Since the industrial revolution, we’ve extracted and processed colossal quantities of resources from our planet. We’ve produced a lot, and the amount of waste we’ve created (perpetuated by planned obsolescence) is staggering. Our linear economy takes from nature and makes for people, who use and then dispose. Consumerism keeps the economy ticking; but how long can we maintain this system? Enter the #CircularEconomy. #WickedProblem
