I've stood behind an 87 tercel and I've stood behind a new toyota. There is a difference you can smell. 1975 was one inflection point in emissions with the addition of catalytic converters, 81 was another point with the addition of three way converters, 94 was another with the Phase 1 standards, etc. The high mileage tercels were still carburetted, and there's a reason nobody tries to meet current emission standards with a carb. The new cars are definitely cleaner, and most of the emissions controls reduce MPG. (Other things have improved MPG, like aerodynamics, variable displacement engines, etc., so it's not a straight line downward.)

Refugees tend to be among the most productive people in the country.

Unfortunately, as every European citizen knows by now, that is usually not true in the case of Muslims. It is for most other refugees but Muslims think they are entitled to a pay, house and free everything for doing nothing.

Fucking bullshit.

They even said that the solar roads would be easier to repair - have a busted hexagonal panel? Pull up with a truck that has a robot arm that automatically unbolts and lifts the damaged panel and locks a replacement in. Each panel is supposed to be cheap because it's made in an automated factory.

This kind of thing comes up a lot, and seems to come from people with no clue how roads work. Repairing the surface is the easy part. Repairing the subsurface is hard, and putting some glass on top isn't going to change the fact that you've got a major repair involving a lot of earth moving equipment if the subsurface of a road is compromised. Just throwing a new piece of glass over a sinkhole isn't an option.

The problem with roof mounted solar is that people get upset when the government lends people money to pay for it, and each installation is unique. With a road the government (or in France's case often a private company) owns the road, and can lay large stretches of it using a standard process in a well understood and mapped environment.

Real estate management companies can do to the same thing for enormous square footage of basically identical industrial flat roofs, and already are.

Maybe in the US it does, but here it definitely does not. Possibly because we use an earth leakage system with three cables for AC. Earth leakage is much safer - almost all electrocutions have the ground as the return part of the circuit so an earth leakage system means those are virtually impossible. The US I understand uses fuse boxes but we use circuit-breakers and earth leakage. On the other hand, our home power is twice the voltage of US systems so that is probably what justifies using more expensive safety systems - the risk when you get shocked is much higher at 220V.

The US has used circuit breakers for decades. You may be thinking of "earth leakage circuit breakers" (ELCB) but those are pretty obsolete at this point. Current US code requires ground fault circuit interrupters (GFCI) extensively, which are equivalent to the residual current devices (RCD) which replaced ELCBs and have been required for quite some time in most countries, regardless of how the circuits are wired. (And arc fault circuit interrupters (AFCI) are increasingly required in habitable locations.)

None of that has anything to do with power distribution. In the US (and most places) AC is typically distributed multi-wire. Single wire is used in very isolated areas (especially, e.g., Australia). Single wire in the context of this thread refers to distribution, not household service. (Pretty much every place in the world now uses a hot/neutral/ground scheme for lighting service, with additional phases possibly utilized for high-power applications.) The economics of AC vs DC for long distance transmission have more to do with power loss and equipment costs than number of conductors.

Comment Re:Why not a roof? (Score 1) 407

Wouldn't it be more effective to build a "solar roof" over the highway, shading motorists during the hottest parts of the day, angling the panels to maximize insolation at the latitude, and for f's sake: not having to make them sturdy enough and grippy enough to safely drive trucks on them?

And wouldn't it be even more effective to build solar panels on all of the "roofs" that already exist, before building new roofs just for solar panels? There are a whole heck of a lot of really big buildings with flat roofs around the world, only a small fraction of which have panels at this point. Pick the low hanging fruit before trying the kool-aid.

Comment Re:Not Routing (Score 1) 154

Oh, my, it's not even routing. The script just tries a speedtest service without concern for whatever else might be competing with the Pi for transfer.

The usefulness and appropriateness of complaining like this can be debated, but when he connects to a big torrent and his Pi starts complaining that Comcast is being slow - well, that's just an asshole move.

Yeah, it seems pretty pointless/lame. Using a speed test at all for this is kinda sketchy. A better implementation would watch for signs of network congestion (retransmits, etc) and look at the bandwidth consumption at that time, preferably checking that there are multiple congested destinations. (To try to avoid blaming the ISP for a problem on the remote side.)
