I'm not sure I know what you are talking about.SpAc3man said:We must make a giant red mining ship called "Red Dwarf". There must always be somebody called "Lister" on the ship at any one time. There will also be a ship cat. Every Friday the crew will be served curry and lager.
Red Dwarf is the greatest space comedy of all time.blackrave said:I'm not sure I know what you are talking about.SpAc3man said:We must make a giant red mining ship called "Red Dwarf".

Maybe you could explain please
Water? Running low? You mean that wet stuff that covers most of our planet?Wakikifudge said:Ya they aren't really concerned about iron or gold.

The reason why iron is more common than than gold is due the laws of physics, the heaver the element the less of it of created by fusion in stars or by super novas. Yes there are vast quantities of minerals out there but they are going to be in roughly the same distribution you find on Earth. In other words you going to find vastly more iron than you are gold. Even at todays prices iron ore is dirt cheap. Even if you do find a 20 ton lump of pure gold, what do think that's going to do the price of gold? The markets can respond quicker than you can get the gold on the ground. The more you find the less its worth.
There was a great article I read not too long ago about some of the elements we use for electronics that is running desperately low but is found in great abundance in asteroids, if only I could find it.
I never said we were running low but they plan on collecting this water and keeping it in space to save on the costs of having to launch it from Earth. Here's a link that goes a bit more in depth than the one provided and which gives a couple paragraphs to the possible uses of space water: http://news.yahoo.com/asteroid-mining-venture-backed-google-execs-james-cameron-011205183.htmlarc1991 said:Water?

Don't mean to sound stupid, but how on earth is that running low...surely if worse comes to worse they could just purify seawater, removing the salt and making it safe to drink? :S
You obviously had the same thought as me. As soon as I saw this article, I went straight to Netflix to watch Red DwarfSpAc3man said:We must make a giant red mining ship called "Red Dwarf".

Bout the time we get carbon nanotubes perfected. The main problem right now is that we don't have anything capable of withstanding the stresses that such an elevator would withstand.juyunseen said:This is all well and good, but when are we finally gonna figure out how to build a safe space elevator?
Well at least I got an actual answer on that. I was fairly certain we didn't have the right materials, or at least not enough of themCpu46 said:Bout the time we get carbon nanotubes perfected.

Yea but a lot of people predict that Carbon Nanotubes are going to let us make stuff like space elevators and massive structures. And once we have a way to easily and cheaply (well relatively cheaply) move materials to space there should be a whole new space revolution.juyunseen said:Well at least I got an actual answer on that.

Not really. as far as comets and fly-bys go, such huge bodies as saturn or jupiter with their gravitational pull serves as a much better shield. as far as gas clouds and radiation goes, asteroid belt does not affect it, the sun radiation cloud behind planets does.Am I'm only one concerned here?
Asteroid belt of solar system serves as a shield for Earth
Mining them would be risky
if the consumption trends continue, the drinable water will run out in 50 years around. purifying sea water at such high amounts as we consume would take enormous efforts.Don't mean to sound stupid, but how on earth is that running low...surely if worse comes to worse they could just purify seawater, removing the salt and making it safe to drink? :S
