there are more tyrannical equations if you are promoting space colonization. I mean if you compare earth to a petri dish, what do you think a small domed shelter on some other planet will be?!?
I like space, lots of neat things to learn, but the discussion always seems to get a little religious and doomsday-ish, and I find it less than genuine. Like have people thought about where the energy to get massive numbers of people off the planet will come from, and how that will leave the planet in even worse shape for those that can't leave?
It is folly to think technology can fix everything, and I sometimes wonder if it has actually "fixed" anything, aside from helping to enable overpopulation.
- groby_b 8y agoThe energy to get a human off the planet is relatively small. Let's call it an MWh. (It's 9.1 KWh/kg) A billion people is a PWh. That's 0.5% of the earth's annual energy use. It's a blip on the radar, especially since it will subsequently reduce annual consumption in the 10% range.
- hackerpacker 8y agofactoring in Tsiolkovsky's equations, it seems more like 30mwh, and that is just one person, and just the fuel, not the processing or the preparation or even building a rocket, without any life support, or landing plan. plus where are you going to send %10 of the population where they will be immune to human nature, whatever that is.
