He does get a bit passionate, but is his science right?

Is it a con, or just a very starry-eyed idea?
Can other sources of power be used to make this possible? (Depending on the country, Wind, Water, even Thermal)

> If the science is right:
Are the people who think the SR is not possible energy company shills?
Will this give as much return as they claim?
Will this work in other countries?

Why would you put solar panels on the roads instead of beside the road or above them?
Or hell even better, put solar panels on dedicated spots that get maximum sunlight, like deserts - oh wait, those are called solar plants and already exist.

It's literally retarded.

Idea didn't seem terrible, but as a Canadian the most significant problem I see is that their plan is to have the roads heated to melt snow and ice during a season where we have the least sunlight reach the ground. The net loss in energy would be pretty massive.

It's a pipedream, anytime something good looks like it's going to happen, or is doing well, it never turns out. EVER. There are black niggers in charge of stuff, since then the only advancement since 1969 is that silicon printers got higher resolution, and therefor can print smaller microchips. (The higher resolution is due to faster processors, which was caused by higher resolution silicon printers, and they have fed this cycle since the 60s. If it looks like things are advancing, YOU'RE WRONG. Nothing is changing, the internet is just a mere series of tubes, that evolved into a series of glass wires (technology from the 60s) Supply and demand, and competition, along with lower manufacturing cost has provided technology that could have been developed in the 60s to the public, and that's why computers are better and cheaper.

There almost no major technological advancements, everything that is considered an "advancement" is just built on the original model built from the 60s

The great thing about solar roadways is that you can dismiss the idea with the same logic and facts that you can use to dismiss solar, then apply about a factor of 10 because of the way they want to implement them.

Solar power doesn't match grid demand. Peak demand falls after the solar PV output falls to nothing. What this means is that you need a number of fuel fired plants on standby that can meet all of the grid's demand, which would be producing no power for the daily demand.

What it means is that plants that have real construction costs, and ongoing depreciation costs will only run for about 4 to 6 hours a day. Yes it saves money on fuel, but it costs money due to the lack of selling a profitable product the rest of the day.

Their is no grid level storage medium that is even dreamed about today, that would be cheaper than building a gas plant that burns gas all day to keep it's turbines at operational temperature, just to run for 4-6 hours. (and that's even counting the huge loss of revenue for building something that only runs for 1/4 of the day).

If you by magic made a storage device that was economical, it would be cheaper to attach it to a nuclear power plant, or a coal power plant, or a gas power plant and charge it during the lower demand times so it could meet the higher and peek demand.

Solar panels are best used in locations without access to grid power, or in ultra low energy requirement applications.

Unless your grid power provider is running diesel generators (or solar PV) as it's only power source, home use of solar PV panels and the storage and inverters needed to produce useable residential power will never pay for it's self or ever cost less than grid power.

Even better, in case of a fire, a growing number of fire departments around the world will not fight a fire in a house with a large number of solar panels because of the real risk of electrocution from the huge number of batteries needed to make a solar system work.

It's a fucking pipe dream.

Solar panels of today's technology are not even close to being efficient enough to provide the power for even the LED road markings, let alone the snow melting heating elements they're talking about, and the thought of them piping excess power back into the grid is a fucking joke. It will be decades before the math works out, with the current progression of solar cell technology. You'd be better off going piezoelectric for the fucking things.

That's not even taking into account that these things are fucking *roads*, which cars drive across all day, blocking sunlight and depositing dirt/rubber all over them.
What about the optical properties of the glass they'll have to use? It needs to be tough enough to drive trucks over, so it'll have to be really fucking thick glass.
What about the grip levels of the glass? What kind of surface will the glass be? Will cars slide straight off during a rainstorm, or will a rough surface be applied, further disrupting light transmission?

Just basic examination of the current state of technology, what they want these roads to be/do, and what problems may come up, just doesn't pass the smell test.

Instead of shitty batteries, I'd store solar energy by chilling a large tank of water and running that through a radiator to help with cooling during the time between when the sun is no longer directly overhead and late at night when it's cool enough outside that the air conditioner can shut off.

It's probably still a shittier system than a geothermal sourced heat pump.

Residential demand peaks in the evening though, when people are getting home from work, turning down the AC, cooking dinner, etc.

Still far less demand than the actual peak during the day.

It's likely due to the LED, micro inverters, components to run as a network, components needed for other features, angle, dirt, etc, that solar roadway panels will cost more to make than they'll provide for in energy, installation isn't free, maintenance isn't free, etc.

So, in the end:
It costs more to make the panels than you get out of it
It's unlikely the panels will even produce more energy than they use
It's extremely unlike the panels will produce more energy than is used to make them.

protip: everything on kickstarter is a scam or developed by retards.

so you combine the worst way to generate solar power and the worst way to pave the roads and voila you have solar roadways and you are now officially retarded. sage sage sage.
>>
>>43203724
It's not the roads that freeze over it's the water that seeps into cracks into the road that freezes, expands, and makes the cracks bigger.

Unless these panels are tight between each other frozen water will cause the same problems.
>>
>>43203998
They can't be tight against each other, because cycling from -10°F to 140°F every year will tear them apart. Even regular concrete roads with gaps left between slabs buckle in the summer.
>>
The idea is insane for one reason alone
Asphalt currently works out for large scale road building to be around $0.20 per square metre. These panels will wor out to be around $15 per square metre to install and operate. The energy they use will be approximately 4 times the energy they save
Any government that tried to implement this would have to be certified insane and locked up
>>
It's so costly that we could give every driver in the US a top of the line electric car,and still have enough money left over for the electric car infrastructure.
>>
>>43204040
They also can't be tight together, because the surface of the road always has a tiny slope for rainwater. When the road is straight it slopes from the middle, and when the road is curved the slope goes down towards the curve. That would not be achievable without many different tile shapes, which would increase production costs even more.

If solar roads ever worked, it would have to be with a bendable, rolled, or paved form of solar cells, and not tiles/panels.

I've personally worked as a grunt on both on roads and on solar farms. Paving roads with glass would be like paving roads with an extremely breakable and expensive form of ice, except even more slippery than ice.

Yea, I'm sure these glass panels will be able to sustain hundreds of cars driving over them for 18 years.
Note that they've only driven a tractor on these panels. Sound impressive?
Not really. Roads need to be able to support the weight of hundreds of cars and they need to have good traction.
Also, how the FUCK do they think they're going to transfer the energy harvested from the roads to an electrical plant?
All small details, but important ones nonetheless. Fun fact, the cost to put just the LED's into these pieces of shit (assuming that they replace every single paved road with their shitty solar roadways like they claim they want to), the cost is in the billions.
TL;DR: This is all bullshit.

>Solar panels are best used in locations without access to grid power, or in ultra low energy requirement applications.
Photovoltaics are best used close to the point of load. Right now, with storage being what it is, it makes sense to have the grid available as a buffer when you can. If you have for instance an office, or some sort of industrial site with the roof space for PV and some kind of load that's active during the day (like when people are in and working), it can be a great complement. PV (concentrated solar thermal is another story) has a big advantage in that it can be scaled down easily in this respect.

Now, we do need better grid storage, if even to attach it to coal/nuclear/whatever. Or better yet, ones that could be distributed all around closer to the points of load. This makes the grid more resilient, and evens out demand.

Frankly, I wish there was more research into large-scale storage than into eeking out an extra 1% efficiency in PV.
>>
I think this is probably bullshit, but I kind of want to see them try. I mean, just to see how much it fails, or if by some chance it kind of works. I'm not going to give them any money, but I'll keep an eye on it.
