So it is more expense than just a road and solar panels by themselves and less efficient.

The ONLY benefit might be the government saves money by not needing to buy new land.

Solar panels are already horribly inefficient at extracting energy. In order to have a transparent road strong enough to withstand traffic, it'd have to be meters thick. The transparent material will absorb most of the energy from the sun before it ever got to the solar panels.

The first Solar Roadway installation was in Sandpoint, Idaho, where the inventor lives. Despite only having foot and bike traffic, they were constantly in need of maintenance. They also were often snowed over, needing the inventor or a city employee to clear them off, as the built in heaters that were meant to melt the snow didn't receive enough power from the panels to do so.
It's just another one of those ideas that sounds good when discussing from a high level but once you get into the implementation details, it fails miserably.

>In July, the French daily newspaper Le Monde reported that the 0.6-mile (1 kilometre) solar road was a fiasco.
>In December 2016, when the trial road was unveiled, the French Ministry of the Environment called it "unprecedented". French officials said the road, made of photovoltaic panels, would generate electricity to power streetlights in Tourouvre, a local town.
>But less than three years later, a report published by Global Construction Review says France's road dream may be over. Cracks have appeared, and in 2018, part of the road had to be demolished due to damage from wear and tear.
>Even at its peak, the road was only producing half of the expected energy, because engineers didn't take into consideration rotting leaves falling on the road.
>It was all smiles and high hopes in 2016, when the world's first solar panel road, called Wattway, opened. France spent US$5.2 million on 0.6 miles (1 kilometre) of road, and 30,000 square feet (3,000 square metres) of solar panels. It was hailed as the longest solar road in the world.

god these people are fuckin retarded to even think for a second that this is a good idea.
just put a damn roof over the road (a carport a long as the road) and cover the roof with solar panels.
would keep the road surface and the solar panel equipment separated as two discreet systems.
allow for the maintenance and upgrade of either system without interfering with the other system
would protect the road surface from a percentage it's exposure to the elements

not retarded

learn the difference

[Anonymous No.15228749]

Off of the top of my head:

1. Inefficiency. most solar power farms have a system that allows the solar panels to face the sun. Not doing this yields half (or worse) as much energy. Now combine that with cars constantly blocking the sun, along with the necessary rough "clear" coating for traction and you'd be lucky getting a fourth of the efficiency per panel.

2. Cost vs Practicality. Installing miles of customized solar panels is inherently expensive. You may say that the energy generated is worth the initial costs. However, when maintenance is needed it is no longer a one or two man job like in the case of a solar panel farm, but instead an entire bureaucratic operation of hiring entire teams to redirect traffic, replace parts, install signage, and so on. Not to mention maintenance workers will have to learn a new, privatized method of working, as opposed to the current ubiquitous methods of transport repair, and cities will have to pay a premium to a handful of companies with patents.

Overall, i think these two factors make remote solar power farms much more attractive to cities. The idea seems interesting and smart at a glance, but after a bit of thought melts into novelty in my opinion.

I swear the culture war kills fucking brain cells. It turns everything into a knee jerk response.

It's a cool idea. It's obviously not going into use everywhere any time soon. It's the type of thing you pilot at a loss to see if it makes sense, maybe only for small areas that are hard to get electricity too.

I could see it for a richfags driveway out in the desert to help with power generation.

Obviously not replacing most roads anytime soon, especially not in places with heavy wear, rain, or snow.

I think the small pilot solar sidewalk in Idaho spent $8,700,000, including money from taxpayers, and it makes about $1.00 of electricity per month.
Not exactly a good or worthwhile ROI, especially considering the fact that solar car-parks produce significantly more energy while also providing shade for vehicles.

They received grants for R&D, the projects have been donation funded.

150sq ft installations were never going to be a big power generator. The idea is to raise money and awareness to keep iterating because it only works if you get costs really low.

Tiling any town square with bespoke tiles, even ones that don't generate electricity, is always going to be more expensive than an industry with massive economies of scale.

there's this cool technology called 'sumulation' which allows you to approximate piloting new technologies like this, only at a fraction of the cost of actually piloting them. e.g., for the price of a mere few moments of your time, you can posit your query to a mongolian throat-singing simulator and receive near-instant feedback from dozens of board-certified weaponized autists on how monumentally foolish such an idea is

So all of the dirt, tire dust, oil, and exhaust particulates that build up on a normal road, are they going to magically not be a problem here?

[Anonymous No.15230359]

A typical panel contains about 33 grams of copper.
According to PDFs regarding the project, 7,500 panels are required per kilometer of road (these figures made no mention of road width, however).
There are about 4.17 million miles of road in the US highway system.
Therefore, 31.275 billion panels are required to replace all highways (probably more).
This comes out to ~1.03 trillion grams of copper, or 1.03 billion kilograms.
This is roughly half of the total amount of copper in Earth's crust. Not the amount that we can feasibly or economically access. Half of all copper. Just for the US. And not even all of the roads in the US, those are just the numbers for the highway system.
