Power is not a serious problem at Mars distances. For the cost and scale of a manned Mars mission, football-field sizes solar panels are perfectly affordable and practical for the spacecraft - also compact to launch (relatively) and deploy since they don't need to support their own weight against gravity like they do on Earth.
Yes I'm sure all those physicists have not "done the math" on how to get power out of a reactor. I mean it's just this big important aspect of reactor design which you could get a Ph. D in by running simulations and doing the math, so I'm sure no one anywhere is looking at it.
This is a hybrid rocket engine.
The problem with hard core security guys is that security is there job and they wind up being unable to imagine that it's not actually the job description of other people.
Good luck with that? My VPN endpoint is in another country as is the company. They're going to have to do a ridiculous amount of enforcement and blocking, much of which would wind up contravening WTO treaties, to actually limit it.
Of course the fact you need this service is still ridiculous.
If you're an adult, you got over being called names. Expecting others to sanitize your environment wherever you go is insanity.
This exact same logic works right back at you.
They're probably doing both? The recent mystery star discovery was a result of human analysis of transient light curves which were missed by the current side-effects.
There's no practical reason you couldn't fill unmanned high altitude balloons with hydrogen.
Judging by Oracle's previous updater efforts, nothing. This is the same company which couldn't be bothered to make a Java updater which could check for updates without producing a UAC pop up.
"a power transfer rate of 6.9 kilowatts" is absolutely meaningless. Rates involve Time. 6.9 Kilowatts per _what_ exactly?
You might want to look up the definition of a kilowatt.
"People" don't do that.
Americans do that.
Countries with the metric system use metric as natural units because its what they're familiar with.
It is however a threshold situation. The tools and technology to build a solar panel to sustain us like that would make it cheaper to build the next one. Once we can do it once, economic growth would dictate that we pretty obviously should build another to get the most out of the investment. Repeat to the logical conclusion...
It could also simply be *not a dyson sphere*. A matroshka brain would actually be somewhat more consistent - clouds of thinly spread dust, punctuated by a few planets or planet remnants in the process of being disassembled.
Seeing as how the star is never completely occulted, but the predicted object sizes for some scenarios have to be substantially larger then the star, then it would be somewhat more consistent.
Planets are inefficient at providing living space.
Were there fewer fools, knaves would starve. - Anonymous
