Roads paved with...solar panels?

An Idaho-based company started a crowdfunding campaign to meet US's future power needs. How? By building solar panels into parking lots, driveways and roads.

Solar array at the Marine Corps Air Ground Combat Center in Twentynine Palms, Calif. Solar Roadways is a company that is crowdfunding a project to manufacture its interlocking solar panels into existing infrastructure.

If there's one big problem with centralized solar power facilities it's that finding the space to build them is quite difficult.

But what if you could take existing infrastructure and put it to other uses?

Idaho-based Solar Roadways aims to do just that, and is crowdfunding a project to manufacture its interlocking solar panels on a wider scale – with the ambitious (but laudable) aim to meet our future power needs, charging electric cars, and even homes, using our roads.

Before you even get to the product's application, the product itself is rather fascinating, comprising hexagonal glass tiles that act as a solar panel and computer all in one.

Glass doesn't seem a natural fit for a product that's designed to be driven on, but Solar Roadway founders Scott and Julie Brusaw have come up with a design and construction that stands up to the rigors of use--passing traction, load testing and impact resistance testing without issue.

To prove it, Solar Roadways has produced a video of a tractor being driven over its solar panels – without any nasty cracking sounds...

Each panel contains a layout of photovoltaic panels – currently covering around two thirds of the tile, with the eventual aim of 100 percent coverage--and is laced with microprocessors.

These allow for "smart" panels, that relay information as well as generating energy. Combined with a patchwork of LED units, the panels have nearly limitless potential as far as road markings go--from denoting lanes to active, real-time arrows, words and signals.

A thin mesh of heating elements is also buried within the tile, keeping them snow-free – beneficial for both generation purposes, and keeping road surfaces safe in winter.

The Brusaws have just unveiled their second-generation prototype, in the form of a solar parking lot.

It still needs work – Solar Roadways intends to cover the mounting holes for each tile, fill gaps between the panels and come up with a software system for controlling the LEDs.

The parking lot prototype also shows the couple's realism with the task at hand. It's wildly unfeasible that roadways will generate solar energy in the short term, and possibly even for decades and decades to come.

But by starting small – with driveways, bike paths, patios, sidewalks, parking lots, playgrounds, as Solar Roadways puts it – the concept can be tested thoroughly before its application on a larger scale.

The potential for parking lots in particular could be great, allowing them to go "off-grid" yet provide enough power for future electric vehicle demands. After that, Solar Roadways suggests its product could be used on quiet, residential roads--before a future move to highways.

Solar Roadways has started an Indiegogo crowdfunding campaign, hoping to generate $1 million in start-up funds.

The concept has currently raised $170,000 with 17 days to go – and Indiegogo's flexible funding plan means the company will be able to use any funds it generates to work on the project.

A nationwide – or worldwide – network of solar-powered roads is a long way off. But if Solar Roadways' panels prove successful on a smaller scale, solar sidewalks or parking lots may not be far off.

What is the Monitor difference? Tackling the tough headlines – with humanity. Listening to sources – with respect. Seeing the story that others are missing by reporting what so often gets overlooked: the values that connect us. That’s Monitor reporting – news that changes how you see the world.

Dear Reader,

About a year ago, I happened upon this statement about the Monitor in the Harvard Business Review – under the charming heading of “do things that don’t interest you”:

“Many things that end up” being meaningful, writes social scientist Joseph Grenny, “have come from conference workshops, articles, or online videos that began as a chore and ended with an insight. My work in Kenya, for example, was heavily influenced by a Christian Science Monitor article I had forced myself to read 10 years earlier. Sometimes, we call things ‘boring’ simply because they lie outside the box we are currently in.”

If you were to come up with a punchline to a joke about the Monitor, that would probably be it. We’re seen as being global, fair, insightful, and perhaps a bit too earnest. We’re the bran muffin of journalism.

But you know what? We change lives. And I’m going to argue that we change lives precisely because we force open that too-small box that most human beings think they live in.

The Monitor is a peculiar little publication that’s hard for the world to figure out. We’re run by a church, but we’re not only for church members and we’re not about converting people. We’re known as being fair even as the world becomes as polarized as at any time since the newspaper’s founding in 1908.

We have a mission beyond circulation, we want to bridge divides. We’re about kicking down the door of thought everywhere and saying, “You are bigger and more capable than you realize. And we can prove it.”

If you’re looking for bran muffin journalism, you can subscribe to the Monitor for $15. You’ll get the Monitor Weekly magazine, the Monitor Daily email, and unlimited access to CSMonitor.com.
