China are only making so many emissions because we are buying stuff from them. It's not Chinese peasants who are driving Chinese demand. They are an exporting economy.

Not having descendants is probably a bigger positive contribution to reduce emissions that he can make. There's already enough humans around to ensure that the species survives, at this point him having children will not positively affect the species and will just hasten resource use.
In space, one of the most difficult things to do is dissipate heat. You can radiate, but you can't convect or conduct heat away from you. For a practical demonstration, get a vacuum flask, fill it with boiling water, put it in the freezer and see how long it takes to cool down.
The Death Star has a massive laser-of-doom weapon, which almost certainly produces a huge amount of waste heat. Dumping that heat is likely to be a priority, because you want the planet you're shooting at to be destroyed, not you. Being able to vent coolant in large amounts quickly from the middle of the station is probably very important.
The whole assumption that we should be discussing this for autonomous cars is a bit bizarre. There are millions and millions of cars driven by people, so we should discuss for them first.
As the summary says, you typically don't have time as a human to make a conscious rational decision about what to hit in a collision. In contrast, an autonomous car can do a lot of processing in a tenth of a second.
And the article is a bit stupid because it forgets a few things: One, a crash with a bigger car is worse _for me_
Not necessarily. A larger car can have bigger crumple zones. If its crumple zones are twice the size of the small car, then the acceleration that you'll experience in the collision is a lot less and so there's a greater chance everyone will survive (assuming that the relative impact speeds will be the same).
Second, it's unlikely that two other drivers made mistakes simultaneously, so it would make a lot more sense to crash into the car whose driver caused the problem
That contradicts your first point. Are you using your car as a weapon to punish the guilty driver, or are you using it as a means of ensuring your survival? It's quite likely that it would be better to swerve into a car travelling in the same direction as you that hasn't made any errors to avoid hitting an oncoming vehicle that is doing something stupid (like being on the wrong side of the road). The relative velocity of the impact will be considerably less.
You better not go outside then. You get a lot more than 100uW/ms of radiation from the sun.
SPARC isn't exactly hard to get, and it's supported by gcc. You can even download the HDL for the SPARC processor (which you can't do for intel).
If Iranians needed SPARC kit, they would get it in pretty short order.
The smartphone's biggest detriment to me is all the data that resides on it, and how much the apps track your every move.
