Just in time for Japan to have no exchanges to regulate. (Other, I guess, than LocalBitcoin. Which may or may not count, and would be hard to deal with anyway.) Or does someone know of one that doens't show up on any of the charts? Gox

You can get USD in and out of CampBX. You just have to do it with money orders. (Which is nearly as fast as ACH, though much less convenient.)

If you watch your browser you can see if it does or doesn't. You only need trust your browser at that point. If you don't trust your browser, you can monitor network activity as the OS level. Should provide a pretty good assurance

Legal reasons, almost certainly. I don't know about Finland or Germany or EU specifically, but it seems likely they have "money transmitter" requirements to combat money laundering. I doubt the regulators and/or law know

by jccooper 13y ago
Quite possibly. I'm not concerned with power transmission so much; that's just engineering, and the tiny Centennial Challenge teams were doing well enough over a few years that it seems quite soluble. We will probably have UAVs fl

The counterweight platforms would be a great place for services now performed by geosync satellites. Probably you would also have major GEO platforms in areas not (yet) served by a tether. Take a tug there from the nearest tether. Would rea

It will likely be much thinner than that. But that is a problem. Most plans assume "once manufacture becomes possible and cheap enough". Of course, ordering that much (once a process is proven) will quickly drive down the price. T

1. The counterweight is in geosynchronous orbit. It is "held up" by its absurd speed like any other satellite. 2. One of the reasons you need a very strong material. The tether will be in tension, but probably will have quite a bi

by jccooper 13y ago
Impossible. It must be on the equator. Attaching a line from the ground to a large object in geosynchronous orbit is the essential plan, and GEO only happens above the equator.

We already monitor very small debris (anything 1cm or larger), and move things out of the way if needed. The ISS moves about 6 times a year, mostly to maintain a very large margin. Orbits are quite predictable, and moving the tether around

Not all that much, really. An almost-empty rocket stage is very light, and it doesn't take much to slow it down from terminal velocity (which can be rather low if you fall right) to 0. In fact, one of their main problems seems to be th

I repent using the broad brush against NASA. It's a very diverse organization, and above I mean the "big ticket vehicle design" side of NASA. And the core of their problem is that the whole program was basically designed by C

by jccooper 13y ago
NASA would design a new feature, send it through half a dozen design reviews, apply a few pounds of paperwork, test it on the ground, test fly it (maybe) once, and then deem it "correct" and fly it as-is forever. Manned. This happ

A touch (on a physical object) can make a change in half a second, requires no thinking, and can be done without looking. Voice control (even if it works reliably, which it does not today) takes several seconds and requires thought in compo

A proof-of-stake system (see PeerCoin) might be nicer than encouraging Bitcoin-style proof-of-work mining throughout the network. Possibly it could even be run on simple nodes, as it doesn't require gobs of processing power.

Not too far into their paper, they posit "tunnel nodes" that connect isolated mesh clusters through the normal Internet. As the network grows, they imagine that tunnelling through the Internet will become rarer.

Hard to say what happened from the sketchy reports, but there's been some mention of "mechanical problems" due to lunar dust, and hibernation problems. I guess they have some mechanical movement involved in hibernation mode.

About time. There's long been a "MtGox price" and a "real price", and a price index should not include MtGox unless and until they're liquid enough not to distort the price.
