Anyone else hear about this idea, I think its pretty clever. Building non-atmospheric water ice/liquid inflatable craft and using the water as a low thrust high impulse engine fuel. This design also, potentially, solves other issues like hull integrity, radiation shielding, self-sustainable life support and maybe even supplying oxygen and hydrogen gases.http://spacecoach.org/
Why aren't we building a moon base yet?

So hear me out guys, getting on the moon is seriously important. Why is it so expensive and difficult for us to send things to space? It's because of 2 things, breaking free from the Earth's gravity and surviving re-entry into the atmosphere. All of our rockets, satellites, space probes, etc. have to have a massive amount of fuel and ablative armor. The moon is located in a strategically beneficial spot, right at the top of Earth's gravity well. Once we spend the initial capital to establish a permanent or semi permanent settlement on the moon, the door to space really opens. We can then design our spacecraft without the need for massive thrust and armor, and wont need to spend nearly as much fuel to get around out there. It doesnt take much to move an object through space, and breaking free of the moon's gravity is exponentially easier than breaking free from Terra. And moving resources from the moon to earth is even easier, just a little push and they fall back to earth on their own. With even a tiny colony on the moon to act as a port of sorts, the trouble of monetizing space mining is essentially solved. Not to mention the insane amount of solar power that can be gotten from the raw, unfiltered power of the Sun. We need to do this guys, we're quickly running out of several natural resources, rare earth metals in particular, which we're only just beginning to rely heavily on (theyre used in just about any battery, especially phone batteries and electric cars) and they can all be found in the asteroid belt. The Moon is the answer, and it's right at our doorstep. If we could get there in the 60's with the computing equivalent of a dollar store calculator, then we have no excuses to not go with today's technology.>TL;DR- fuck solving world hunger or social issues, lets just go to the moon. 22 posts and 8 images omitted.

We won't be having hamburgers in space. Or milk or eggs, for that matter. For every cow slaughtered for food there must be an incredible amount of food grown to sustain the cow. In space stations this may not be feasible due to limited space and resources. We'd be better off focusing energy on hydroponics and a vegan diet would probably be necessary in a long term colony or space station. 19 posts and 5 images omitted.
