  • A solar panel requires sun, let's put them somewhere where it can constantly be blocked. Makes perfect sense...
  • I'm sure dirt and abrasion on the surface can't possibly reduce their efficiency.
This green politics run amok, I haven't researched it but I can tell you why the road. Because putting them in the median or the side which may actually make a lot of sense would take up green space.
  • Panels generate the least amount of power while laying flat
  • Tiles are a very poor road surface (ever drive on a brick road?)
  • Using tiles necessitates tremendously more foundation work to be even
  • The required textured surface traps dirt, reducing efficiency
  • Unknown what the longevity of the texture of the surface is, and its coefficient of friction after wear
  • The glass/polymer surface has to be epoxied to the panel, making them non-recyclable. See other solar roads that have de-laminated.
  • The most efficient solar setups are in a centralized location. With solar already being low efficiency, why make it even more so?
  • Solar roads require inverters in short distances, greatly increasing the complexity and cost.
As for the median, it's already been done: https://www.fastcompany.com/3048661/...ile-solar-roof

In South Korea, they covered the median/bike path with solar. This a) provides shade to the cyclists, b) prevents all the issues of having solar on the road.

Interesting philosophy.
Who is we? You on the other hand are welcome to make your own bets in the casino.

Should the calculations look favorable, somebody will make the next (better) attempt. And so on.

We'd still be in the horse & buggy era if it was up to some folks.
Yep, "Solar Freakin' Roadways" the original promotion video has 23 million views now.

The calculations do not look favorable. It was always a silly idea and thoroughly debunked from the start by engineers. Road surfaces just aren't a good place to put solar panels.

Better to put your energy in solving problems, rather than arguing with people who are betting against humanity. The Trumpists don't care what happens when they are gone, as long as they can indulge for now, all is good with them.
You donít have to be a Trump supporter to wonder if it just might be more efficient to spend the money elsewhere. Protecting the environment is important to me and I do believe in global warming but this seems a waste of resources.

There is an abundant supply of rooftops yet to be used. Roads can wait.

As with innovations in the past, you learn a lot from the failures, and build on that for success in the future.

That's amazing that they even tried that. Wow.

That's what people said about going to the Moon.

You learn a lot from attempting new things,and you can use those failures to build on for future successes, and use parts of the projects in different applications. So many inventions that we use in the modern world arose from the innovations for the NASA projects.

The fact is there are plenty of roofs to use and in case you haven’t noticed massive failures like this provide political opponents with something to ridicule environmentalists and solar proponents.

You would think they could have duplicated what these tiles would go through and realized it wouldn’t work before spending all that money to provide political fodder for their opponents.

Exactly. Oops, Apollo 1 had a tragic fire that killed three astronauts. Let's scrap the whole Apollo program. Won't work, doomed to fail, better quit now.

Hindenburg disaster kinda made people rethink hydrogen blimps.
