Cut the brown wire, not the grey wire
Eyes would be useless, as they would supply mostly noise and very little, if any, information. Deciphering this mess would need vastly more brain volume.
Oh, and designing a useful color monitor for computers would be horrendously complex.
This poll confirms this fact (assumption: Slashdot readers are predominantly male).
Use electricity to synthesize hydrocarbons, run trucks (and planes, and ships) with those.
or that Oil is used for more than just energy.
Oil (and natural gas) is also used as a source of hydrogen. Which can also be produced using electricity.
Oil is also used for making lubricants
Wind can NOT be counted on.
Wind availability can be determined statistically. And the more turbines you install and the large the area covered, the less likely you are to run into a "no wind at all" situation.
Also: Name the battery technology and I'll name the resource you'll run out of if you're trying to build capacity in the TWh range. (possible exception: sodium-sulfur cells).
Because some thing don't upgrade well individually.
Say you want a new processor. Unfortunately, that sometimes requires a new mainboard, and new RAM. The new mainboard might require a new power supply, and since the old PC case doesn't have front-panel USB 3.0 connectors, you're getting a new case, too.
While you're at it, you might as well upgrade your video card and hard drives, and at that point you've ended up with an almost completely new PC.
No, the test needs to be so difficult that no one can get 100% without cheating. Then it's easy to spot the obvious cheaters.
This might work for technical breakdowns, but not for external events. ("All coolant pumps and emergency generators fail - because the whole power plant compound is under three meters of water.").
Yes, absolutely. I can look up what kinds of radiation X emits and its specific activity.
You have a point. Lets put it this way: I don't really care if the OS eats up 5 MB or 50 GB of my hard drive as space is cheap these days. I do mind, however, if the OS or the software it is bundled with is annoying, obtrusive, obnoxious, useless, superfluous, unnecessary or outdated and makes me spend time to get rid of it.
Actually, that's the job of the PC manufacturer. You know, stuffing the recovery partition with four dozen marginally useful programs that make you spend two hours to remove them after a Windows reinstall.
