Solar road Ségolène laughing

[Grelinette]

I wonder if the engineers working on it really believe it.

This is the reflection that I made myself!
But I also tell myself that it seems difficult to launch projects as technical and as expensive, requiring specialized skills, if there were irrefutable technical and scientific arguments proving the impossibility of the concept or its profitability ...

Either this project is very (too) innovative, which explains the criticisms it receives,
either it is a costly mistake that will waste a lot of public money (except for the companies working on this project),
either it is a politico-financial manipulation to fill the pockets of some promoters of the project (industrial, political, financial, ...).

We will know in 2020, in just 3 years, when this electricity should be profitable ... Wait and see!

[Petrus]

I especially think that the objective has never been to be profitable but to serve as a showcase.
High-tech patterns on the floor, it is visible and it looks good on the photos, so perfect for making com '. So politicians can show that they care about the environment and encourage innovation in renewable energy
As for the company that installs the panels, the viability of the project does not matter as long as it makes money.

For me that's it.

If the company researching and promoting such an aberration truly believed in it, they would not have waited for subsidies to do so.

when you showed this nonsense, I thought it would never go to realization!

I was not aware of this "project".
When they showed this to the news, my instinct as a designer whispered to me that it was a beautiful thing ... ie!
Thank you for confirming it digitally with this video. (https://www.youtube.com/watch?v=HOZBrHqTJk4)
And what about the maintenance, durability, and adhesion of this coating actually?

In general when you want to perform several functions with a single product, it hurts, look at the duck: it swims badly, works badly, flies badly.

when you see a road you have to be stupid to put the photovoltaics where the vehicles pass there is so much surface available elsewhere, the slopes, the roundabouts the noise barriers

putting photovoltaics on the south-facing slopes would cost nothing more than ordinary photovoltaics, would cost nothing for maintenance and could even save the flaking of the slopes

avoid mowing on condition of being well mounted, that is to say with real walls between the ground and the photovoltaics, so that nothing grows below ... do not take model on certain solar paneneu on the ground or the vegetation continues push between the panels which complicates maintenance

The solar route, a source of noise pollution according to journalist Cyril Biotteau from AutoPlus magazine. "Suddenly with the same coating we can not even imagine the noise on the highway". And in addition its roughness leads to an increase in fuel consumption.

it confirms debility!

solar on the road it makes noise

solar on noise barriers, it would cost less than on the road and it would reduce noise instead of increasing it

I see a different figure like 13 to 17 times more expensive for solar on the road compared to ordinary solar ... how can we be foolish enough to spend as much to look for the problem?

[Grelinette]

Without passing judgment on this project, which requires skills to assess its value, we must not forget that our environment minister Ségolène Royal is not a specialist in the matter either, and that she promotes of this project probably on arguments that specialists have kindly presented to him.
The real question is to know who are the "specialists" who put such a project on the minister's table, and what are their real motivations ...

To be able to withstand the passage of trucks, you need a very resistant and hyper-expensive resin and polymers (energetically and economically). Resin and glue = Bouygues-Colas patents.

Since the yield is crushed (the PV cells are sensitive to temperature + effect of horizontality + shading + soiling etc.), it is necessary to consume a lot more PV cells per unit of energy delivered, as well as all the material which goes with: cables, electronic equipment etc.

From the start it is easy to understand that this techno leads to an impasse.
But Ségolène thought that this "red carpet" would be a good way to get people talking about her. The road is jolie On the photos.

For the energy media of the Heinrich Böll foundation (German ecological think-tank with international influence):

"What this new project in France demonstrates most of all is that French decision-making structures do not have enough internal review mechanisms." Is there really no one within the French Environmental Ministry who understands that at least 6 euros per watt for just the panels is an awful deal? ” (...) asks. In comparison, roads could be shaded with solar - put solar on stuff, not stuff on solar - at a cost of only 1.5 euros per watt, and ground-mounted arrays now cost less than a euro per watt in France. In order to build nuclear, France relied on its elite system of experts, which tolerates no outside criticism; if you want to have a career as an engineer in France, you toe the line. "
