Solar Roadways?

@Placeholder it's like this old Radio Yerevan joke.
Listeners ask us if it's true that in Moscow they give away cars for free. We are happy to confirm that this is indeed the case.
Except not in Moscow, but in Leningrad.
And not cars, but bicycles.
And not give away, but steal.

Yes, I know I'm bringing this back from the dead. But it's for the public good!*
Anyway, in what should come as a surprise to absolutely no one, the test solar road in France - the first on ever made - has been declared an utter failure.
*And if you believe that, I have a bridge to sell you.
-
Yeah. But it wasn't built because it made sense; it was built for political reasons.
-
@Zerosquare France was planning to build 1000km of them. I wonder if that's still on the table.
-
Since it costs money and doesn't generate any, I doubt it.
-
@Zerosquare nonsense. As long as it can enrich someone important at the expense of the taxpayer while putting up a thin veneer of environmentalism, that is really all that matters.

That would require a very big table.

@HardwareGeek Maybe even a table with solar panels.

There is also the German Solmove. It's doing about as well as the rest in the short bus class.

Ugh. Haven't you been reading the thread? Solar panels need to be inclined to face the sun and anything you set on the table would reduce their efficiency.
-
@Polygeekery Not if they're quantum.

The problem-plagued road is producing just half the solar energy expected -- although that's more energy than you'd get from an asphalt road. But Marc Jedliczka, vice president of the Network for Energetic Transition (CLER), which promotes renewable energy, offered this suggestion in the Eurasia Times. "If they really want this to work, they should first stop cars driving on it."

@izzion That's a good idea. Maybe they should put the solar panels somewhere cars don't usually drive, like on roofs of buildings. Too bad nobody's ever thought of that before.

It seems, since they don't mention anything about putting energy into the roadway, like a First Law violation, aka, a perpetual motion machine.
Yes, magnetized particles in a road could generate an electric current in a car moving over the roadway. But unless there is some sort of active component (e.g., electromagnetic coils in the road making the magnetic particles vibrate), the car moving over the road must be using more energy to move than the magnetic field is inducing in the car. The only place for the energy to come from (again, in the absence of an active component not mentioned in the article) is the car's own kinetic energy. You know what happens if you take the car's kinetic energy and convert it into electrical energy? It slows down or stops.
-
In a brochure, Magment said its product delivers "record-breaking wireless transmission efficiency [at] up to 95 percent," adding that it can be built at "standard road-building installation costs"
Uh huh. 95% transfer efficiency you say? Good luck with that.
If the final quarter-mile test track is a success, INDOT will use the tech to electrify an undermined segment of public interstate in Indiana.
I hope they meant to say "undetermined". I would not suggest doing anything to an undermined road except shut it down and repair the undermining.

Ah, but we'll only add it to downhill roads!

If it's undermined, they need to mine it more.

Put those kids to work mining cobalt and lithium and whatever for the batteries.

Not sure if you're whooshing or trying to play dumb to expand the joke. Either way, amusing.

@Polygeekery I thought it was just a pun. Under-mined. Not mined enough
-
@hungrier Not sure how well that turned out for the miners in The Expanse (which is worth a watch IMO).

They could always add a wind generator on the car as well.

Or just power the hydraulics from wind instead of the usual electrical pump. You only need power steering or brakes at speed anyway.

@Carnage I'm pretty sure I already posted that years ago but searching, warthog, nodeBB...
-
@acrow said in Solar Roadways?:

Not really. You can more easily do without power steering at speed. At low speeds and especially when stopped power steering becomes much more necessary. At even moderate speeds power steering doesn't help that much.

Also and because we're not in the garage, it's basically what @Carnage said, a wind turbine on the car. Then look at the pictures (not too hard for you?) to see what happens, and the end is "you did 50m, let's try again and this time you'll cross the Channel!" with an untranslatable punch line ("we'll strike a blow" which in French can mean "we'll make history", the other guy responding "OK, let me start").

What are the odds that they all have it - but it's disabled unless you pay for the option?
-

Many years ago, I used to drive a Peugeot 206 with a large and heavy diesel engine. That didn't have power steering, and manoeuvering around a parking lot was a tremendous upper body strength workout. But once you were going more than about 5–10 mph, the steering was not particularly heavy at all.
It was a good car… until it started rusting so fast that we couldn't really weld it quickly enough to keep the pieces together.

An old joke from back when a significant number of cars didn't necessarily come with power steering:
"Does it have power steering?"
"It has Armstrong power steering."

Around here no AC was sometimes called '4 zone AC'.

That was the 455 AC unit, in the US. 4 windows, 55 miles an hour.

Driving out of Phoenix, I had to turn off the real AC and turn on the 455 unit. It was so hot (117F) that my car was overheating on the climb heading north on I-17.

Some variation on "450 air conditioning" is the joke where I am from.
4 windows down, going 50 mph.

No, actually, that's just left out of the article. This brochure here actually makes mention of external power supplies.

Well, except this part of the brochure:
Electric planes, flying cars and hyperloop coming next. Right. I guess their charging devices could work — if the vehicles they're charging could.
