solar roads: a shining idea with a big price tag  -  all in one solar street light price
Bring the vast network of roads and sunshine across our country and turn them into energy. -
Build a highway.
The idea of solar panel roads is still in its early stages of development, but it has attracted wide attention in many countries around the world.
It will carry out a real experiment on the world's most iconic road. -Route 66 -
It is called "the main street of America".
A couple begins-
A company in Idaho called Solar Road has proposed replacing traditional asphalt roads with glass-based solar panels in an effort to turn roads into renewable energy sources.
Scott and Julie Brusa raised nearly $3 million through online fundraising to achieve their ambitious goals.
The company plans to test-drive its products on a small section of the landmark highway in the hope of generating enough energy to power a rest station.
The French government recently announced plans to cover 1,000 kilometers of roads with solar panels over the next five years.
The country's National Solar Energy Research Institute, in collaboration with a French road construction company, has developed solar panels less than a centimeter thick and laid on the top of the road.
This is an initiative that they hope will provide renewable energy to 5 million people.
The Netherlands is also experimenting with this idea and has built the world's first solar bicycle road in 2014.
After six months of testing, Dutch researchers said it was more successful than expected, generating enough electricity to power a machine. -
Family members for one year.
What is the following?
That sounds exciting, but there are obstacles to this idea, which some renewable energy experts question as inefficient and too expensive.
Andrew Thomson, a solar researcher at Australian National University, admits that the idea is attractive, but warns at this stage that it is a slightly misguided idea.
"It's a very attractive idea," Dr. Thomson said.
But although "technically feasible, the price is very expensive.
I really don't think it has a market. Its opportunity cost is very high.
However, others, such as the famous scientific personality Karl Kruszelnicki, who is mainly known as Dr. Karl, are more optimistic about its potential use.
"This is an interesting concept.
I like the idea, "Dr. Carl told the news. com. au.
"The advantage of using roads as solar cells is that people don't like roads, so they're glad you can put things there, like solar cells," he said.
Dr. Carr believes that these projects could pave the way for the construction of solar roads in Australia.
"I think the solar road is only a small part of the whole renewable beautification program.
I don't think that's the only solution, "he said.
This is a very attractive idea, but many solar researchers are not entirely on board.
They are concerned about high costs, relatively poor road solar performance and other options, such as roof installation and potential safety problems.
The price of building roads with thick tempered glass sheets is about four to five times that of typical asphalt/asphalt roads. -
The gap is unlikely to change.
If solar panels are made of recycled glass, the performance of solar panels may be impacted by more than 50%.
Supporters claim that the energy generated by roads will compensate for the cost, but that is meaningless if there are more effective alternatives.
"I don't understand how they will prove it economically," Dr. Thomson told the news. com. au.
Performance If the solar cell is partially masked, it will significantly reduce the energy generation of the panel.
Considering that roads are not sun-oriented and can be covered by buildings and cars driving on them, the performance of solar panels will be significantly reduced.
Idaho's solar road technology has many beautiful features, such as self-
Heating ensures that there is no snow or ice on the road, and the panel can alert drivers to animals crossing the road through a lighted panel.
But for some solar researchers, these potential benefits are not enough to outweigh the "relative inefficiency" of road technology.
Dr Thomson says it does have its place, but ultimately it is a niche market.
When the world disappears from roofs and other empty places.
"However, as Dr. Carr pointed out;
"As the cost of manufacturing solar cells decreases, it's not important that they don't generate maximum energy.
"There are also safety concerns about the long-term wear resistance of solar glass.
The wear of asphalt pavement is only to expose more rough asphalt layers with the same consistency and grip.
Although solar glasses will work with surface topography to increase traction, over time, homogeneous materials will wear smoothly.
Dr Thomson said: "It's a good PR campaign, but I think if you really launch it, when people start crashing, your PR campaign may be terrible. "
Dr Thomson has taken a step in the right direction, which is not the only criticism of the solar path.
Referring to the French government's plan to pave the way with solar panels, Craig Morris of Renaissance Economics said: "It's enough to despair you. "
"Can anyone tell French leaders that solar power is a bad idea? " he wrote.
At the same time, stocks.
Com calls the plan a "high-cost, inefficient prank".
Senior editor Joel Anderson severely criticized the idea as "putting government money into an inefficient and costly form of solar power generation, despite the obvious good options available.
"In fact, it is still a strange phenomenon that this idea continues to gain support in different parts of the world.
For Dr Thomson, he believes that there are some subtle psychological factors at work, which is related to-
Natural coercion to improve the environment is ultimately a very unfriendly activity that makes people so excited.
"I think that's where it comes from," he said.
However, he believes that this may weaken ongoing projects and move them towards a more energy-efficient world, preferring to see resources flow to more viable projects.
"We don't need to look for that silver bullet, we need to find something that really has the potential to succeed in reducing electricity costs," he said.
