Because it's a retarded idea. Maintenance would be impossible and the roads are covered half the time.

it's about the worst place to put solar panels

>>107034071
If this succeeds your 10,000 can become 10 million. If it doesn't then one of your other bets will make up for it. It's fundamentally a great idea, just hard execution.
>>107034093
how so? There is nearly unlimited road, roofs are limited and powerplants are costly and built far away requiring major capital.

>how so?
they have to be made strong enough for cars to drive on them, they'll become dirty and torn up before too long. roads are made of the material they are because it's super easy to repair/restore
they're constantly shaded by cars, trees, etc
you can put solar panels around roads, either above/beside/between them, but not where the cars go, that's just retarded
i don't think it's practical to have LED signage on them, either, as neat as it'd be ignoring practicalities

>>107034267
>It's fundamentally a great idea, just hard execution.
No, it's a fundamentally flawed idea. Roads need a lot of maintenance, and you'd need reinforced panels that can take several tons of pressure (trucks drive over roads too).

Better idea: build a parking lot near the road. It would provide shade for cars, and the sun would be always shining on the top with 0 obstruction. The only maintenance you need is having to clean bird shit off the top every now and then.
Or like the other poster said, put it on the walls in the middle or on the side of the road.

The only valid use for this solar shit. But instead they cover square miles of valuable farm lands with it.

Why put solar panels on the road when you can put it next to it?
Why have LEDs on the road when you can just paint the road and exploit the fact that a giant ball of fire is shining light on it for half the day.

perhaps efficient would be a better word
like in >>107034296
the panels are;
- out of any sources of shade
- installed at a more efficient angle (can't angle a road, solar panels are rarely installed flat for a reason)
- don't need to use thick reinforced glass panels to support the weight of trucks, which probably also means light transmission is better
- easy to upgrade/replace/repair without interruption to traffic
just to name a few

Solar roadways are a interesting conundrum.
Everything that makes the solar roadways better also make regular solar panels better.
It is a situation where solar roadways will never be better than regular panels.

>>107034465
You can angle road panels, just not the glass on top. Glass can be a special cheap formulation and cost will fall below asphalt with scale. Advances in semiconductor manufacturing helps create supply-chain for ultra clear, yet durable glass. Panels are modular so local damage can be fixed in minutes not hours or days.

>>107034509
>You can angle road panels
Yes, but then the cars will just fall to the side of the road and roll.

perhaps, i'm not sure how solar panels would be affected if the cells and glass were at different angles
>Glass can be a special cheap formulation and cost will fall below asphalt with scale.
while everything costs less with scale, asphalt is highly recyclable, roads are less manufactured and more refreshed, you basically just melt it and repave it. i wonder how much more energy would be needed do the same with glass? remember, any more energy needed to maintain this road will be coming off any energy it creates, you can't only consider how much it makes when it's working

>Those all sound like engineering challenges, not theoretical ones.

So you are saying that instead of theoretical challenges, you have practical challenges preventing them from economical or even functioning, and wondering why people don't build them?

>Since the opening of the road, panels have routinely come loose or broken into pieces. In May 2018, 90 meters (300 feet) of the roadway had to be destroyed. It was quickly apparent that the solar panels couldn’t withstand the wear and tear of sustained traffic or the forces of nature.
>engineers didn’t take into account the damage that would be caused by thunderstorms, leaf mold, and huge tractors that would be using the road.
>In the first few months, the highest amount of energy generated from the roadway hit only half their stated goal at around 150,000kWh before falling to 78,000 in 2018 and finally 38,000 in early 2019.

A roadway could have trucks running over it and rain falling on it, who could have anticipated such a thing.

roads take an absolute beating, which is why we use a material which is extremely easy to recycle and reuse, because we know that there's no such thing as a permanent road

>>107034640
solar roadways are modular.
>>107034620
I can point to a million planes prototypes that failed to fly, yet today air travel is essential.

>>107034648
>solar roadways are modular.
that won't mean much when you have miles of panels where tyres hit them the most which are all worn to a smooth glass finish and warped non-flat after a few years compared to the rest which would probably mean redoing the whole road anyway
replacing one panel that got cracked for some highly-local reason is one thing, but roads don't typically wear out in one highly localised area

>>107034648

Simple, the panels as they are powered can even house their own hydraulics, they sense pressure and can expand, the middle panel will simply expand to be flush with the panels around it.

The idea is built under the idea that there is an advantage in placing solar panels on the roads instead of the sides of the roads, and this is false.
It's like selling tires made out of stone, going for the premise that "stone lasts more than rubber", and going all "we're going to improve the stone until it's better than rubber!"

You have a below freezing IQ. There is absolutely an inherent advantage to dual-purpose roadways rather than have a road taking up space and a solar panel taking up separate space. I don't think solar roadways are practical but honestly this might be one of the dumbest posts I've ever read on this site.

No, it's the type of idea that an idiot who thinks he's smart has. "This asphalt that I'm looking at appears to be flat and black, and solar panels are flat and black, therefore we should combine the two."
Anyone with basic critical thinking skills can immediately see why this is stupid.

He expects you to put effort in figuring out what this means, and trying to disprove it is futile since he hasn't committed to any definition of theoretical or practical problems.

Just nonsense, took zero effort to type it and it's very difficult to argue that it's false (it simply has no informational value).
Even better:
>What could be more useful than a road?
He doesn't even state a criteria for usefulness, just throws the statement over the fence and braces himself for (You)s.
Useful for transportation? Yes, that's why we fucking build and maintain them.
Useful for solar panels? Of course not, that's retarded and will never be done as long as there exist wheeled vehicles. When we all have flying cars then sure, roads may be repurposed for solar panels, just like roofs are currently used for this.

>>107035624
Who are you quoting? It's a fact that you have 0 experience in the field same as me. How many experiments have you run on the viability of solar roads? My guess is 0. Possibilities are unlimited, if you think outside the box I'm sure there is a viable solution to the really very minor problems (that asphalt already has btw, and doesn't generate capital).
When the cost of solar roads experiments are so low (a few million) and the benefits so high (easily trillions in value even if we don't consider LED utility), we would be foolish to ignore it over minor NIMBY quibbles.

>>107035840
>and the benefits so high (easily trillions
These benefits are only in your head. Electricity needs to be generated close to consumers, and there are no consumers anywhere near these sunny roads by definition, or else they wouldn't be sunny.
On top of that, intermittent electricity (solar, wind) is worthless, it is priced at 1/10th of gas/coal/nuclear/hydro electricity. Sometimes less, even zero, check the historical feed-in tariffs in your area.

the maintenance costs got higher than the money saved.

>>107035979
Electricity from the road can literally benefit every electric car driving on it via wireless charging,

>>107036489
>>107035979
Not only that, but once you have the wireless charging infrastructure your road doubles as a electric generator from the motion of cars through it's magnetic field.
