Solar Roadways !!

Sustainable Issue: Energy Efficiency

Technology:  Solar roadways

The Solar Roadway is a series of structurally engineered solar panels that can be driven upon. It replaces all current petroleum based asphalt roads, parking lots, and driveways with Solar Road Panels that collects energy to be used by our homes and businesses. Solar Roadways Incorporated is a start-up company based in Sandpoint, Idaho founded by Scott and Julie Brusaw in 2006. The company envisioned in replacing asphalt roads with solar panels. The proposed system would require the development of strong, transparent, and self-cleaning glass that has the necessary traction and impact resistance properties. Their technology includes a transparent driving surface with underlying solar cells, electronic and sensors to act as solar array with programmable capability.

There are three layers for the solar roadways –

  1. Road Surface Layer.
  2. Electronics Layer.
  3. Base Plate Layer.

For solar roadways to be successful, the three layers of solar road panels need to work in unison. The road surface layer needs to be clear enough to let the sunlight pass through it to the electronics layer. The electronics layer collects solar energy. It consists of photovoltaic cells which converts this energy into electricity. This energy received is transmitted to the base plate layer and also it keeps the road functioning properly, and the base plate layer determines where the energy is supposed to go and distributes power (collected from the electronics layer) and data signals (phone, TV, internet, etc.) to all homes and businesses connected to the Solar Roadway. Because the road lines on solar roadways are LEDs, the baseplate layer needs to ensure that the roadway has enough energy needed before sending the rest of the energy out towards the grid. Solar cells produce DC energy. Homes and businesses currently use AC energy, so the DC solar energy is converted to AC energy by a DC-to-AC converter or solar micro inverter and then is fed to the homes and other places.

Stake Holders:

  • Manufacturing units
  • Energy Manager
  • Commercial building users
  • Utility Company
  • Federal highway department
  • Engineer

Deployment / Implementation:

Step one: Showcase the reliability of the technology to the public and private entities. Attract more investors and spread awareness about the usage to this technology.

Step two: Set up some full-scale prototype units to prove the principles in real-world conditions.

Step three: Form partnership with utility companies (Solar and automobile industry) that could use this technology to demonstrate the efficiency of the technology.

Step four : Implementation of the technology along with the government.

Portable Toilets by Harleen

I think the concept of Portable toilets should be appreciated for their durability, easy to use functionality, and modern design, light weight, easy to wash and move. However, my only concern is about cleaning. Proper knowledge about the cleaning process should be taken from the retailer from where you buy the mobile toilet to maintain healthy hygiene of the users.


One thought on “Solar Roadways !!

  1. I think roadway paved with solar panels instead of asphalt is a brilliant idea that could potentially change our energy generation portfolio toward more renewable energy. While the concept has been around for years, issues with its affordability, reliability, and durability still impede the implementation of this awesome technology. With the perfection of solar technology and energy solution, solar panel roadway may also charge our EVs wirelessly while driving so that EV drivers would not have to stop at charging stations. Having that said, roadway paved with solar panels also poses new challenges to stormwater management as it may increase the impermeable surface of our cities even more.
