My point is that overyone here seems to very seriously underestimate the cost involved with putting solar panels over a road.This is why you put them on roofs and parking lots first before you consider roads.
Just the aspect of poles near roads is dangerous, power pole impacts cause large numbers of deaths in crashes for example.
QuoteBut it is exactly the reason why companies with loads of money and smart engineers are trying to combine solar panels and roads.
No, the money comes from the government looking to virtue signal about the environment, and from the public who gets duped into slick crowd funding campaigns.
QuoteSo far not very succesful but technology needs time to develop. It took Werner von Braun years of experimenting and crap loads of money and effort to get a working rocket. That ended up with sending people into space about 20 years later.
The delusion you have is remarkable for someone on an engineering forum.

We have plenty of water, why not floating panels?
All in all it seems your entire solar roadway debunking is based on the idea that Colas and Solaroad got a bag with money for free to tinker with. And then you are calling me delusional? Epic!
For the record: I never said solar roads are the ultimate solution but you have to respect the engineering process and see where it goes. A more balanced approach is much more informative than pulling funny faces and slapping your forehead.
QuoteNo, the money comes from the government looking to virtue signal about the environment, and from the public who gets duped into slick crowd funding campaigns.That is a big urban myth. In Europe it doesn't work that way. One of the reasons is that government handouts aren't allowed by the EU. I've worked at a research institute and several smaller companies and I'm well aware of how government funding works (several projects I currently work on receive government funding). As I explained before the funding comes from tax cuts and discounts to have research done at a research institute but before you can take advantage of a tax cut or to get a discount you have to spend money.
For example: if I buy a piece of equipment for $1000 I can get a $400 tax cut. But I'm still $600 in the hole. If I don't spend the $1000 then I don't get the $400 tax cut. There is no free money flowing towards me so I have to make sure the piece of equipment makes me at least $600 to break even.

So can you tell us how those projects were financed--who paid for what and how much?? Were they expressly an experiment or was there a stated expectation of performance?
The projects I work(ed) on where financed by companies using own or venture capital. And no, there is never an expectation of performance. That is the whole point of doing research; to go of the beaten path and find something new.

Well.... 45% of EU fund money is suspect of fraud:
http://publications.europa.eu/webpub/eca/special-reports/fraud-1-2019/en/
Knowing that "low carbon research" is up-to 80% EU-funded, some business can get idea to write off other than "low carbon footprint energy research" expenses. Disclaimer: it's educated speculation.

And no, there is never an expectation of performance. That is the whole point of doing research; to go of the beaten path and find something new. The government funding is to help limit the risks if the research going nowhere. But it isn't a bag of money; just a tax cut or discount at the end of the road. So in general projects are executed in small steps in order to keep the losses to a minimum if it doesn't work out. This also works the other way around: if a company invests a lot of money in a project they are likely on to something.
Only very fundamental research at universities and government related institutes get money directly but these projects undergo a lot of scrutiny including peer reviews before committing any money to them and the result is usually nothing more than a scientific report describing the experiments which where performed and their outcome. Fundemental research doesn't produce a product you can sell.
No, this page says that 45% of the fraud cases lead to prosecution. If you read further you'll see that the number of detected frauds is 0.29% of all payments with the majority in Cohesion and fisheries.
I wish all this money was being spent on making nuclear power safer and more time spent on thorium breeder reactors.
My point is that overyone here seems to very seriously underestimate the cost involved with putting solar panels over a road.This is why you put them on roofs and parking lots first before you consider roads.But there aren't enough roofs to begin with in the Netherlands and probably large parts of Europe. So seeking alternative places for solar panels before all the roofs are used is a good strategy.

The project is funded by the French energy ministry, while in the summer Royal had also announced the mobilization of €5 million in state funding to support the development of the Wattway photovoltaic panel at the Société Nouvelle Areacem (SNA) factory, which is in the same area.
Currently there is no thorium reactor, so we can't be 100% sure what are the side effects, and it is more dangerous than solar cells. Solar cells already work.
There are power plants like this, which produces 115 GWh per year (note: "GW/h per year" which you wrote is physically nonsense) and needs 1.6 km^2 space. Don't know from where you got the 17 TWh number, but total energy consumption in Australia was 4,000 TWh in 2013. Of course, this includes all fossil consumption for heating etc. So one solar power plant of 56,000 km^2 could provide all the energy Australia needs.
Currently there is already 1/3 produced as renewable energy, with hydro the most with 17%, which makes sense, because for this you don't need batteries for the night.

So seeking alternative places for solar panels before all the roofs are used is a good strategy.Rubbish. Don't make me get out google maps and prove you wrong.
One every roof and parking space is covered, then come back and we'll talk.
There were no solar roadways, it had never been tried, so we didn't know 100% what the side effects were. Thorium reactors are far less dangerous than solar roadways, more people have died on a road than they have been by nuclear reactors.
The system only produced 110GWh from solar, and 2.5GWh of Fossil fuel.
"Fossil backup, night time preservation, and morning pre-heating, is provided by natural gas and provides up to 2% of total output.". So this plant produces more CO2 emissions than a nuclear reactor.
Currently there is already 1/3 produced as renewable energy, with hydro the most with 17%, which makes sense, because for this you don't need batteries for the night.
According to government figures. The actual percentages for 2018 are:
Wind: 5.74%
Hydro: 6.06%
Large-scale solar PV: 0.38%
Small-scale solar PV: 3.41%
Total Renewable: 16%.
I wonder, how difficult would it be where after putting panels on a building, they then work to cover areas like parking lots with them (just large enough to provide shade for cars parked in the spots, but to leave the aisle clear?
For example, like this

I'm not pulling numbers out of my ass. So please go ahead and prove a multi billion dollar firm wrong.

Yes, I think we all agree that solar roadways are a bad ideaBut comparing how many people have died on roads to emphasize the safety of nuclear reactors doesn't make sense. How many people have died because of Chernobyl?
And how many people have died because of standard solar cell installations?
This is also right. But it does produce 98% solar cell generated energy. And it is possible to replace the natural gas consumption by batteries, but might cost more.
You are right, this table was misleading, the numbers in parentheses was the actual output, the numbers I quoted was the registered capacity.
But your number seems to be too low as well. When I look at the table O9 on page 11 in the report you linked, it says "total per cent renewable generation: 19%" for 2018. But this is only for electricity generation. If we want to replace heating, car fuel etc. all with renewable energy, it would be much less percentage, and a long way to go. But I think much better than any non-renewable power plant, like a nuclear reactor.

From this Wiki article
"The steam-blast effects in the initial moments of the accident would ultimately cause two deaths of those in the facility, in the emergency responding that followed, 134 firemen and station workmen would be hospitalized with acute radiation syndrome due to absorbing high dose rates of ionizing radiation, of whom 28 died in the days to months afterward and approximately 14 suspected radiation-induced cancer deaths, would follow in the initial hospital admitted group of 134, within the next 10 years.[12][13] Among the wider population, an excess of 15 childhood thyroid cancer deaths were documented as of 2011.[14][15] Due to the often long Incubation periods for radiation exposure to induce cancer, the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) has, at multiple times, reviewed all the published research on the incident and found that at present, less than 100 documented deaths are likely to be attributable to increased exposure to radiation.".And how many people have died because of standard solar cell installations?
How many people have died from falling off roofs installing panels, or fires occurring as a result of falts in the solar panel installation?
From this article:
The fifty actual deaths from roof installation accidents for 1.5 million roof installations is equal to the actual deaths experienced so far from Chernobyl. If all 80 million residential roofs in the USA had solar power installed then one would expect 9 times the annual roofing deaths of 300 people or 2700 people (roofers to die). This would generate about 240 TWh of power each year. (30% of the power generated from nuclear power in the USA). 90 people per year over an optimistic life of 30 years for the panels not including maintenance or any electrical shock incidents.This is also right. But it does produce 98% solar cell generated energy. And it is possible to replace the natural gas consumption by batteries, but might cost more.
Lithium batteries are dangerous to the environment. Let's not mention Lead-acid batteries either.You are right, this table was misleading, the numbers in parentheses was the actual output, the numbers I quoted was the registered capacity.

But I think much better than any non-renewable power plant, like a nuclear reactor.
My numbers were based on table O1.
Don't get me wrong, I am all for solar energy, we just have to be real about it.
Arguing that nuclear power is more dangerous than solar is like arguing plane travel is more dangerous than driving by car. Just because we here about nuclear incidents or plane crashes, doesn't mean they are more dangerous than installing solar panels or driving a car.
Many parts of Europe have been safely utilizing nuclear power for decades and we can do even better.
.... ....
Nuclear accidents have terrible consequences ...

I'd like to see nuclear power development of systems where meltdown is not a risk and high pressure containment structures aren't needed.
