No, because Mark went into orbit in a fair dinkum Russian spacecraft, which he got to fly (partly) himself. The vehicle being discussed here won't go into orbit.
Too right. If you think a workmate has HIV then stay the hell away from their saliva.
Remember kids: AIDS is transmitted via sweat, saliva, tears, breath and mosquitos... or not. We are not allowed to talk about anything possibly related to sex so we leave you in the dark. Happy paranoia;)
More dangerous would be something like you sending off a workmate's saliva to see if they have HIV and then using that information to force them out of a job, etc. That's the sort of casual mis-use that we *don't* need.

Who says we have to restrict ourselves to the surface?
Then its a bit like putting the Earth at the focus of a mirror. We would need to find a source of cooling at the same time. Don't want wind up like the Puppeteers.
Burn the Hydrogen down to Methane, then use the methane with existing technology and infrastructure. Crack atmospheric CO2 to provide the carbon for Methane so you have a closed cycle.
>>Yes, but we don't know it works everywhere, and energy use rises with standards of living and we may not be able to afford that happing in the third world.
It has worked in every country where conditions improved, except Saudi Arabia and Israel, and there's reasons for those two guys.
Energy issues are mostly overrated. If Benin ever developed a strong middle class, there'd be plenty of options to supply them with power, not even counting coal or gas.
What about India and China, at the same time? Maybe you are right. The point is we don't know what will happen until we try it.
Microwave intensity follows the inverse square law so as the ball drifts from centre it experiences asymmetric force. Its picky but thats the name of the game in this experiment.
Also what about photons which naturally come off the inside of the cavity?
The solution to the Malthusian trap is to make everyone live at 1st World standards, not the opposite.

I do however think it is selfish to have a large number of children. Its bad for them and its bad for our species to overpopulate. I have one child and we would have stopped at two if we had the choice.
Shuttle can't reach Geosynchronous orbit... actually, if wiki is correct it only gets to around 1% of the necessary altitude:
Yeah though in energy terms it is much more than 1%, so the shuttle is closer than that. The real problem is that the shuttle was designed with so many shaved tolerances than it can really only operate in LEO.
The shuttle is much more specialized than most vehicles out there. It can pull fewer G's than a 747. Its heat shield can barely cope with a return from low earth orbit, once it didn't. I am sure a way could be found to get it to GSO, but you could never get it back. Heating could be a problem while in orbit because the shuttle was designed to spend half its time in shadow.
A reusable space vehicle which could be launched to retrieve or repair the satellite...
...which could fly to geosynchronous orbit. Apollo would have been the ideal vehicle for the job because it had legs in the sense that you could send it practically anywhere and it could aerobrake to a safe landing. A flight to mars would not have been out of the question and an asteroid mission was seriously discussed.
The shuttle was designed for low earth orbit and could only fly there.
Why are there so many stories on slashdot about how awful e-Voting is? Is there a large part of the slashdot audience that seeks a return to pencil and paper solutions, instead of this new-fangled transistorisation? I think your idea makes perfect sense, the situation where a PROM is touched is the same situation as where a ballot box has been broken open.
Perhaps because we know that the average application designer does a really crap job, and we don't want our votes exposed to it. Where I work they would email a spreadsheet around for everybody to fill in their vote.
You can't store up drag and then recycle it as thrust. It just doesn't work like that.
This is just like cycling in undulating terrain. I go faster down hill and experience more drag, so I lose kinetic energy and I am unable to make it up the hill. Just imagine that orbital debris roughly in my orbit provides the drag, like air.
I'd also like to note that I work for a large company that knowingly pays me to do exactly this all day. I write proprietary software using GPL libraries and such all day. We just don't distribute it.
That could come back to bite them quite badly. What if one department gets spun off as an independent business at some point in the future? Not solving this problem up front could create some hidden costs for your employer.

Doesn't Mark Shuttleworth feel like a sucker now?

No, 5 minutes seems about right to me...
OMG yes!
Asimov forecast this is "2010: A Space Oddity".
The monkeys are going to take over, so I'm off to buy bananas... !
Your geek card has been revoked under the Clarke-Asimov treaty of 1972.
Mmmmmm forbidden nipples...

Don't have unprotected sex with them either.

China has a massively growing middle class, and they haven't run out of power yet, case in point.
China are building more coal power stations, which is a major pollution issue.

This story appears to be a dupe.
Iridium, a form of unobtainium, is used. This costs upwards of $13,000 per kg. About 3 tons are produced a year.
We should hope for more cometary impacts then.

Some buses run on methane right now.

...I might consider it. There's no more selfish act in the world than having your own children.
If only your parents had the same views.

that sounds awesome - sign me up!
I'll do that for you right now...

Its not a good thing.
