Mining the Heavens: In Conversation With Planetary Resources' Chief Engineer
cylonlover writes "It wasn't long ago that asteroid mining was only found in the pages of science fiction. Now, with increasing interest in the commercial exploitation of space, companies are springing up to turn asteroids from things that Bruce Willis blows up into raw materials for future travellers and colonists. One such firm is Planetary Resources, which is currently winding up a Kick Starter campaign aimed at raising public awareness about asteroid mining by offering the public access to a space telescope. Gizmag visits the company's Bellevue, Washington headquarters and talks to the President and Chief Engineer, Chris Lewicki."
Long, but worth the time.
There seems to be an attitude amongst certain people that space resources should belong to those rich enough to grab them. There hasn't yet been a serious discussion of paying for this exploitation of nature, and I suspect that is because many of the people involved have a libertarian agenda, and see space as an opportunity to escape any form of public restraint on their activities, and construct their Randian utopia off world.
Given the immense resources of the solar system compared to those found on Earth, this is a recipe for immense, cruel and unfair inequality. Those of us Earthbound, who have motivations other than money and so are not billionaires, will be plunged into poverty by extraterrestrial energy magnates whose obscene resource wealth will make the Saudi royal family look positively frugal.
Quite timely then that someone appears to be making a movie on this theme :)
"Just one has enough hydrogen and oxygen to fuel every Space Shuttle thatâ(TM)s ever been launched."
Providing you have a free energy source, and lots of time and gas storage, in which to convert it all.
Yes, you might get away with a solar panel churning through it for a thousand years, but more likely the energy you need to separate it from the water will cost you more than the energy you get from recombining it with an ignition source to go boom at a later date.
This is one of those "there's enough carbon in a pencil to make 50 diamonds" kinds of things - utterly true, and completely misleading at the same time.
You don't want to be using asteroid water to make hydrogen and oxygen, in space, in large enough quantities to fly a spaceship by the sorts of processes available today. From Earth - yes. But that's because you accept a certain amount of resource / energy loss to achieve orbit.
You can't get more out of banging H and O2 together than you have to put in to separate H and O2 in the first place.
You stupid monkeys have a perfectly useful 3.839Ã--10^26 W fusion reactor only 93 million miles away. Get off your asses and figure out how to use it.
