The Ray is constantly evolving our expectations for a highway. In this ever-changing environment, there's a good chance you might have a question. Here you can see questions we've answered and pose your own. We look forward to hearing what you want to know more about - let's talk!
Great question! The Ray is 501c3 nonprofit charity organization. We receive an endowment from the Ray C. Anderson Foundation and are also supported through individual donations. Many of our projects are funded through the public-private-philanthropic (P4) model, meaning that The Ray brings public/government partners and corporations together with The Ray to fund many of our demonstration projects. The Ray is at its best when we work together across sectors to achieve our common goals! If you go to the Technology portion of our website, you will see a "Powered By" section. This indicates the partners that support the project, financially or otherwise.

The end of 2018 marks the closing out of a five year pilot testing phase for Wattway. After that, they plan to go public with four commercial lines with will provide a diverse range of products from solar roads, like the one on The Ray, or some better suited for urban environments. But before you start a discussion with Wattway about your project, there are a few questions you can ask your team right now to get ahead of the game. What area do you have available for Wattway - is it a sidewalk, bike path, or road? Is it shaded or uncovered? Where will the power go (to a electric bike or car charging station, lights, or a larger interconnection into the grid)? Who owns the space? Who manages the area? The Ray has Georgia Department of Transportation permitting available as a model for anyone who wants to replicate our work. And if you still have questions, please feel free to reach out to us individually! www.wattwaybycolas.com/en/
The Ray has had the opportunity to demonstrate several technologies that are “firsts,” that really make The Ray unique. Our PV4EV (solar fast charge station for electric vehicles) was the first of its kind to be located at a rest stop in the south east. Our Wattway solar road is the first drivable solar road demonstration in the United States, and the second in the world. Our WheelRight tire safety station, which checks both tire pressure and tread depth without the driver leaving the vehicle, is the first in the world. Finally, our pollinator garden located at the Visitor Information Center was the first planted on Georgia Department of Transportation land.

The first thing to understand is that all along the right-of-way, decisions have to be made about the ground cover. Dirt and gravel are unsightly and lead to erosion issues, so departments of transportation look to vegetation. This is why you usually see turf grass lining the road. However, turf grass has a shallow, fragile root structure that makes it difficult to grow, and it requires extensive, regular mowing. We think there are better options and one that we particularly like is the pollinator habitat. Native pollinator meadows use native plants that are drought resistant and optimized for the local climate. They have deep root structures that prevent erosion and protect our water systems from roadside pollution. Pollinator habitats (obviously) provide a home for bees, butterflies, and other pollinators that are critical to the success of our agricultural communities. By choosing pollinator meadows as the ground cover management strategy the right-of-way, we can secure acres of land for these important species for decades. And did we mention that they’re beautiful and can make a road trip or long commute just a little bit better than it would be otherwise?

As long as internal combustion engines still dominate the road, growing crops in the right-of-way is impossible because of the chemicals and pollutants that make their way into the denigrated soil of the right-of-way. However, we see this as an opportunity. Choices are constantly being made about whether land should be used for food or energy production. Because the right-of-way is incompatible with food production, we have an opportunity to relieve some of the pressure for more energy production on food-compatible land and move it to the right-of-way. Additionally, other non-food crops can be grown in the right-of-way. On The Ray we have a perennial grain pilot. This grain will produce fibers that can be used in the production of highly disposable goods like diapers, napkins, and paper towers.
The Ray is a key logistics corridor for the region. There are over 40 international companies located in LaGrange and more than a hundred manufacturers in Troup County - that’s more Fortune 500 companies than anywhere in the United States! This presents us with a unique opportunity. We have planned a future pilot project focusing on connected vehicles (CV), focused on freight activity. A CV study of freight vehicles can help us understand how to make platooning safer, how best to synchronize routes, and how to maximize efficiencies such as drafting. In addition to the obvious economic benefit of this pilot project, there’s a human life component. The Ray is also a tourism corridor. That means that families are driving through on their way to the new Great Wolf Lodge or driving east to the coastal beaches. Crashes involving heavy fright are often fatal, therefore, increasing the safety of semi-trucks that drive up and down our corridor alongside family vehicles is an important part of creating a zero-death highway.

This is a great question! Measuring and effectively communicating the pollution impact of individual cars is a critical step to educating drivers. Connected vehicles outfitted with pollution sensors or drones on repetitive flight patterns could gather general data about pollution levels on the road. That data could then be made available to the public. Additionally, emerging sensor technology could be deployed on The Ray to capture individual car pollution levels that could then be communicated to the driver in an easy-to-understand format. For example, underbridge lighting could change colors based on the pollution levels of the cars underneath. Something like this could be a great public education opportunity to take abstract numbers that represent pollution and make them real!
A DC fast charge can bring most EVs to an 80% charge in 20 minutes. A KIA Soul has a 90 mile range so DC fast chargers need to be located every 50 or 60 miles to ensure adequate charging opportunities. It’s important to remember that while fast chargers are crucial for interstate and highway travel, most travel can be supported by trickle charging, a significantly cheaper option. In urban environments, many people will be able to trickle charge overnight. For charging necessary throughout the day, strategic locations (think shopping centers and office spaces) and infrastructure, like light posts that be retrofitted for a trickle charge hook up, can combine to ensure all EVs have enough options, without the high cost of DC fast chargers.
