They have put in a trial footpath in the netherlands and it seems so work OK. 

 

it really has not https://www.youtube.com/watch?v=6-ZSXB3KDF0

 

 

I have watched all his videos on it. The cycleway is just OK, nothing more nothing less, it works but it is a novelty. Unless I am missing something, that is exactly what he says in the video too. It is nowhere near as good as rooftop solar and does nothing in my mind to prove the roadway concept is ready for using on real roads with cars and trucks driving on them.

 

Yeah nah, would you be happy for your local council to pay for a "novelty" that's otherwise complete junk?

Not quite sure why you are going after me on this, but no, I would not be happy with my taxes going into it when it works only half as well and costs a lot more than rooftop based solar tech. I am not defending the solar roadways and all my comments have said as such. Anyway that is my token fight on the internet for the month

Around here i see brand new seal sliced up to repair pipes after stunningly short periods sometimes.

 

Yes, roads take up a large amount of area but so do rooves (roofs?) and they

 

-don't have to support trucks

 

-often face North

 

-are above shading 

 

-are close to electricity connections

 

if i had the choice of a road or a factory/warehouse roof for my PV farm, guess which one is getting my money?

The dumbest part is that they suggest that the electricity produced by the panels could be used to power street lights.

When we have exhausted cheaper than solar renewables (wind, hydro, geothermal etc), then we can focus on rooftop solar. When we run out of rooftops, then we can look into putting solar other places.

Seriously we have heaps of rooftops, and they are a much better place to put solar panels than roads. i.e. Less shading, impact damage, less dirt / skid marks, less friction wear etc.

The notion that they could be used in car parks is probably the dumbest idea of the lot (and that's saying something!).  

 

Do you know what happens to car parks during the day? (you know, the time when the sun is up). They are full of cars that block the sun's rays!

 

Why on earth would anyone think fitting these into car parks makes any sense whatsoever instead of just putting the solar panels in a tiltable panel on building's roofs so they can actually get solar access all day  (AND don't need to be built to an industrial standard to withstand the weight of cars)

 

 

You might want to be careful about what you accuse of being a dumb idea unless you are sure that your own idea is not dumber.

 

How much of the surface of a car park do you think is covered by cars at the busiest time of the day?

 

Come on, give us a number?

 

According to google 33% coverage is good. Remember, car parks have access routes for cars to drive in and out and the spaces themselves are way bigger than cars so that sloppy wetware controllers can fit their vehicles in the spaces and still open the doors to get out. One reason for google to support the idea of self driving cars is to make better use of the hundreds of millions of dollars worth of real estate that they have to put aside for car parks. Typical car-parks only cover around 25% of the available space with actual parked cars.

 

Car parks have other advantages.

 

* Big heavy rip-up-the-surface trucks are rare or unheard of in most car-parks.

 

* Vehicle speeds and thus associated surface damage levels are way lower than on regular roads.

 

If the tech works then putting it into car-parks does not seem so dumb after all.

Even better would be to put it over the carparks providing shade for the parked cars than underneith them.

Let's imagine that at best only 25% is covered in cars.
Compare that with how much of a roof is covered - 0%.
Not only that but car parks (and roads), by being at ground level, are also going to be in shade from nearby buildings quite a bit. Roofs, being higher up are going to have less shade. (For example, the roof of my house is in shade 0% of the time, but the driveway probably 50%)

Roofs also don't have heavy trucks ripping them up, but not only that they also don't even have to bear *any* weight at all beyond a person. The panel on a roof also doesn't have to be flat, can even track the sun for maximum efficiency. Flat car parks can do that.

I stand by my assertion that putting these in car parks is dumb.
When all roofs that can see the sun are covered in solar panels, then *maybe* we could start considering other, less effIcient locations like car parks

Aredwood: The dumbest part is that they suggest that the electricity produced by the panels could be used to power street lights.

 

My favorite was that the panels could have heating elements in them that could melt snow. So in winter, when solar output drops from all solar sources whether they are on a road or a roof, you could use the energy from solar to melt ice and snow... something doesn't add up.

And in other news solar related, have you seen the megapanels on Apple's ugly campus:

Even better would be to put it [(solar)]over the carparks providing shade for the parked cars than underneath them.

 

 

This would be fantastic.

yep.

 

 

 

that would almost certainly be

 

a) cheaper to install

 

AND

 

b) lower maintenance

 

AND

 

c) waaaaaay more efficient in terms of KWH generated per square metre

 

than putting them on the floor underneath the cars.

 

 

 

Given the above three things that make it clearly and unarguably better than carpark ground based solar, and that there is no real technology limitation to anybody doing carpark roof solar power right now, the fact that you don't see widespread adoption of carpark roof solar should make it pretty clear that the idea of putting the solar panels on the ground is absolutely terrible.

Maybe they could add induction rails at the same time, power those with the solar cells, and run all the cars on 'lectricity.
