In fact, the amount of money is inversely proportional to the probability of bugs. A perfect developer costs an infinite amount of money.
In that case, you'd end up with a gaseous fraction that's mostly hydrogen, and a liquid fraction that's methane plus everything else.
I would assume you'd have to cool the mixture to a temperature between -161.49ÂC and -42ÂC (boiling point of the next heavier alkane, propane), so you get hydrogen and methane in the gaseous fraction, and propane and heavier alkanes in the liquid fraction.
And on how difficult (read: expensive) it is to avoid unwanted byproducts. And on the possible market value of the byproducts.
If you can sell the liquid hydrocarbons that you want to produce and the methane that appears as a by-product for almost the same price, it would be economically counterproductive to spend money on reducing the fraction of unwanted methane. Just produce both and sell both.
Sudden evacuation might be problematic. But with less serious problems, the lower transit time to Mars vs. Europa might be advantageous. You're dead anyway within about 24 months from the lower gravity and radiation (or suicide, if sickness doesn't get you first).
There's no experience with humans living in low gravity conditions for more than a few days. We have plenty of zero-g experience, but none that would tell us what a few months of 1/3 g would do to the human body.
Radiation is a problem, though. Shielded habitats would be a high priority. Either underground, or possibly by using water (produced on-site) as shielding.
In effect, for a few generations, you could introduce intentional mutations that are known to be somewhere between "marginally harmful" and "beneficial", until the gene pool is large enough that things can be left to random chance again, if the colonists desire.
If "one-way" implies using your favorite method of suicide after a few months, then no.
Definitely not. "One eye for one eye.", at that time, replaced the proven concept of "You stepped on my toe, so I'm going to kill you, every male in your family, rape every female in your family and kill them, too."
At that time, when ever-increasing vengeance cycles and bloody vendettas were the norm, "One eye for one eye." was a huge limitation on any punishments the injured party could dish out. And don't forget the same piece of literature also demands things like having at least two witnesses in order to sentence anyone to death and forbid the common practice of punishing family members of the offender if the latter proved to be too elusive.
Maybe Kim Jong-Un wants one for his personal, private collection? The legitimate channels for buying one aren't an option here.
