You never go full Brusaw!
Germany has it's own Solar Freakn' Roadways trial, guess the  results...

I am shocked, SHOCKED, that you doubt German engineering cannot triumph where everybody else has failed!

I noticed a lack of mechanical and material engineers on the team.  These guys just get in the way of progress.

€784,000 €150,000 for a 90m run!  :-DD

These solar roadway projects gotta be a money laundering scheme- the manufacturer, the politicians, the installers, the funding, bullshit marketing... keeps everybody smiling and loading up their pockets.
The manufacturer blames the installers who blame the weather and meanwhile the politicians are putting tarps over it. Unbelievable.

I would guess the interconnects are failing, the module "the surface may be made of glass" I assume it's just cast resin over solar cells and I didn't see any cracked.

In Canada, the winters, ice, frost heaves would trash these. Any water freezing up will kill these with ice-jacking, and sand/silt build up inside that mounting frame.

It was EUR 150,000, see here for the clarification.

Here is the start of my posting, with all the photos you can see in Dave's video, and the high resolution versions (linked for each photo).

Fixed: I took that number from your post as shown in Dave's video. Surely that €150,000 is not including the grants to develop the solar modules. I'm wondering where the money is coming from for Solmove, if it's private investors or just government funded. I've never seen so many institutes, "networks"  etc. involved in all the hoopla. So this is how Europe thrives, everyone works on "fake" projects?

As a sanity check, I tried some math: Each tile 60x60cm, walkway 90m long and 1.44m wide (24 modules), total about 3,600 tiles and 130m^2. Eight screws each- maybe four of those are for interconnects. A bit much.
So that's €41.67 each, installed- including wine and cheese for everyone  ;) €1157 per m^2.

There is no way the total cost of that trial roadway was only 150,000 euro. This is local government job, lots of 'experts' are involved.  A basic kids playground costs almost that much (not including the land) when finished and fully costed.  You have town planers, architects, health and safety, drainage,  electrical supply, street lighting, websites etc.  All this before they even brake ground.

Frank, ask them for a full breakdown of the costs to fully replace a set of traffic lights with pedestrian crossing at a standard 4 way junction.

I have come to the conclusion that Solar Roadways are just a Public relations stunts designed to attract the public's attention to the so-call green economy or anti-fossil fuel agenda.  or CO2 is evil agenda.  yes the Solar Roadways do work but only just work.  as it's all about Public relations!
the so called save the world from CO2 agenda, even thou CO2 is used by plants. even thou this dodgy 1990s computer modeling made its way into the United Nations and got used to get scientific grants & funding on this dodgy doom & gloom the world end by 2012 scientific theory

It might be for installation only? Having troubles translating and figuring out all these agencies and funds. It's this EU "European Regional Development Fund" that appears to have paid 80% of the €150,000?
I'm curious what the rip-off price for the solar modules was.

I did small solar projects in Venezuela and the solar panels were always getting stolen by the locals. I had to hide them in the jungle, and thankfully it's so sunny there that losses were not a problem. These solar roadways, I wonder if thieves will realize there's cash on the ground and pawn the tiles.

This whole solar roadways thing seems to be a "bullshit job", something that keeps many people employed and busy despite being a pointless project at the core.

It seems to me that there are two basic issues with these solar roadways.
 1. The capability of them to withstand the mechanical abuse to which they will subjected
and
 2. Their ability to provide sufficient electrical output to make economic sense.

Let's just assume that addressing the mechanical issues is just a matter of time and ask the fundamental question: Do these things make economic sense?

This is the question Dave has been asking from Day 1 - and the answer he has maintained ever since still holds to be the correct one:  While there are still other places you can mount solar panels - NO.

Let's not get distracted by the mechanical failure circus - although that is entertaining - the whole concept is waaaay down on the list of viable energy sources.

According to the answer I cited, at the moment everything was financed by Solmove. And I think on the webpage or in the interview the Solmove founder said, that he has invested large sums of his own money into this.

I don't think it is the EU fund. They say that the city Erftstadt got EUR 783,000 from the Bundesumweltministerium (Federal Environment Ministry), which funded 90% of multiple projects. Google translation of the official answer, slightly fixed by me:

Quote
In addition to the test route "Solar Bike Path" within the framework of the funding project "Climate Protection in Cycling" of the "Federal Ministry for the Environment, Nature Conservation, Building and Nuclear Safety (BUMB)", several building blocks in the "Infrastructure Ring Liblar" have been promoted, such as the barrier-free expansion of the southern area of ​​the promenade, the Construction of a cycle path along the former railway line on the Liblarer See as connection of the station Erftstadt with the Carl-Schurz-Straße, measures of the public relation, as well as the crossing assistance on the Bliesheimer road in the height of the ErftstadtCenters. For all these measures, the city of Erftstadt has received a grant from the Federal Environment Ministry for the proposed project "Infrastructure Ring Liblar - Changing the Mobility Structure" for 783,000 euros, a 90 percent subsidy.

The test track solar bike path including modules, installation of the modules, information tower, counting station and preparatory civil engineering work is expected to cost about 140,000-150,000 €, with a 90 percent funding, the cost of the city at about 14,000-15,000 €.

So far we have not been able to accept the solar cycle path due to the existing damage; it is not our property. So far, only the start-up has invested (high equity, far beyond the support of the Federal Ministry) and continues to work on expanding the solar cycle path.

The coverage of the station RTL, to which you refer, is unfortunately faulty. The infrastructure ring has been completed in the meantime. The short section with about 90 meters solar cycle path is not yet completed.

I asked the press contact, Mrs. Leder, on this page, with the online contact form.

I posted this in youtube comments, but here it goes as well.
At 11:05 of the video look at the left guy on the bike. As he brakes his front wheel locks up.
If he was riding for real and not cameras, meaning a little bit faster, and had to brake because a child jumped in his path, he would have smack his too-big-for-the-not-even-strapped-helmet head right into those hard glassy knobs.

It's raining and the glass is slippery. Who could have known?

 :palm: I don't see how in heaven's name can these engineers expect these things to be on a highway, where a semi truck or even a garbage truck on city streets may on occasion need to slam on the brakes in an emergency.  All the tiles on the road would be literally torn to shreds as the multi-ton vehicle skids along.  An with electricity there with to aforementioned magic smoke coming out, what do you think would happen there.

It's a clown world now and doesn't matter if it's a Boeing aircraft or these solar roadways, everyone goes along with it knowing it will crash, and collects a paycheque.

Politicians and investors who don't understand the technology are being sold a fantasy:
"This road is not just a road, but a sensor, communication element, power generator and energy carrier for autonomous, electric vehicles."
"Inductive charging of electric vehicles on traffic routes and thus at the place of consumption".

There are moving walkways in some of the subway stations in Chicago, not sure where else in the world they might be used. Not quite a sidewalk but pretty close. Kind of struck me as the epitome of stereotypical American laziness but they were fun to play on.

This would be illegal, you shouldn't do this, you and Dave could get problems.

BTW, here is some background information of the founder of Solmove. TL;DR: He started his job career as a cameraman, then office manager for a talk show production company. After this he founded a software company which went bankrupt. Then another software company which he had to sell to avoid bankruptcy again, and the new owner fired him. In the interview he says that he dreams about to use his solar modules for railway tracks, airfields and house walls as well.

These walkways can be found in other places too. Mostly airports but I've also seen them in subway stations.

This doesn't surprise me at all. If you look at Solmove's website and go to the team page you'll find they have no engineering staff at all. Lets see how this plays out but it is likely they can't fix the solar cycling road. I'm wondering how Solmove is funded. Perhaps they got a loan from a bank based on the forecast to sell a solar cycling road and paid themselves from this loan. Is there some way to get some financial records?
