NO ... we need to perfect our comet mining techniques ... there's gotta be a ton of good stuff out there ... or maybe the first ... MMC ... "Mars Mining...
... I'm just starting a course researching a cutting edge topic in chemistry. Going to do something on fuel cells. Probably related to their use in portable...
I'll be at WWDC [1] in San Francisco from 10th to 16th June if any of the Californian Talk Science members (or indeed members from anywhere!) fancy dinner some...
... I think we're actually pretty close to cracking that part of the problem. We've got cells. The problem is they won't charge fast enough to be really...
... This is true, at least to get off of the surface -- unless JP Aerospace's "blimp to orbit" concept works. If we build space solar power systems, though,...
... I'm thinking more about fuel cells that you supply a constant flow of a suitable fuel to, rather than one like a battery that you can recharge. So when...
Speaking of gas ... I saw a banner on the outside of an autoshop to "ASK US ABOUT FILLING YOUR TIRES WITH NITROGEN" ... anyone ever heard of this or done it? ...
... Yes. The Space Shuttle's landing gear tires are filled with nitrogen; this was discussed at length as part of the analysis forums working though the...
... Quite true, since virtually all of it ends up back as water when we use it, the supply is pretty much inexhaustible. Plus there's LOTS of water kicking...
... Yes, something that you could pressurize with hydrogen in a minute or two would work well. The thing is, the changeover will be slow until it becomes...
I've been thinking about something ... I'm going to pose this idea from a purely acedemic point of view with no particular problem in mind to solve. But lets...
... You would need to control the descent the whole way down to the surface. Once the material you wanted was subject to the Earths gravity it would accelerate...
... Asteroid mining is much better for metals. Comets are lightweight fluff, for the most part, though there are intriguing comet-asteroid hybrids: ...
There have been a few messages recently posted to Talkscience that have been stopped by the Yahoo Spam filters. I'm not getting emails to tell me that there...
... This is actually pretty straightforward. Happily, we don't need to build an enclosure or craft to deal with small chunks -- a very small maneuvering...
... I actually had a misfire earlier today and inadvertently transmitted a reply containing nothing but the original quote. That one can be discarded. ...
... Many of the long term comets that come from the Oort cloud are in retrograde orbits as well. The Earths orbit is prograde and a collision with a retrograde...
Interesting indeed ... I remember a converstaion on debunk a while back talking about the seemingly impossible task of identifying a life threatening asteroid...
... It's just barely possible. A decade ago, C-band satellite dishes were very common -- these are typically 7 to 13 feet receiving antenna for television...
... We need orbital information from potential disasters not just hours before they arrive but years. Optical discovery and tracking is probably the best way...
... Well, I'd agree that it will likely become the primary use. This doesn't mean that providing rare materials on Earth from space sources isn't "real" -- no...
Trying to relax from literally 30 days of working without a break, I plopped down in front of the History channel yesterday and watched a series of shows about...
... Both but mainly the later at present. As more greenhouse gases (not just CO2) are released into the atmosphere more heat gets retained. This rising ...
... That was the "Tunguska event" of 1908, a meteor that exploded just before impact, with a force calculated to be around the Hiroshima bomb in strength. We...
