Solar Roadways: Efficient, Cost-Effective, Scalable

We could literally pave the road in renewable energy.


One year ago, the Netherlands constructed a bike path made of photovoltaic cells, connecting Amsterdam and its suburbs. It was a pilot program to test and show the possibility of solar roadways as a profitable solution.

"If we can additionally incorporate solar cells in road pavements, then a large extra area will become available for decentralized solar energy generation without the need for extra space ... and just part of the roads which we build and use anyway," says Sten de Wit from the SolaRoad consortium in an interview with Fast Co.

The team plans to build on the experience they gained through the pilot program. The initial prototype was pricey. However, the team is looking for a solar road to pay for itself within 15 years of use. As technologies improve, cost goes down.

Elon Musk has demonstrated this kind of product planning with his Tesla series. He has already stated that Tesla will be moving into the third stage of its development plan, producing a mass-market car. It's expected to be priced at $35,000 and roll out before 2020.

“That was the goal with Tesla ... to try to serve as a catalyst to accelerate the day, the day of electric vehicles.”

The company says each square meter generates about 70 kilowatt-hours every year, and the entire roadway generated a total of 9,800 kWh over the course of the entire year, which is enough to power three homes. These are real-world results, which include blockage from pollution, passing cyclists and pedestrians, and weather. 

"Most people do not even notice the difference with a regular bike road," he said in an interview with Fast Co. "That is exactly what we aim to achieve: roads doing whatever they have to do to be a proper road, while harvesting solar energy on the fly."

Surprising Science
  • The new definition of a kilogram is based on a physical constant in quantum physics.
  • Unlike the current definition of a kilogram, this measurement will never change.
  • Scientists also voted to update the definitions of several other measurements in physics.

Understand your own mind and goals via bullet journaling

Journaling can help you materialize your ambitions.

Videos
  • Organizing your thoughts can help you plan and achieve goals that might otherwise seen unobtainable.
  • The Bullet Journal method, in particular, can reduce clutter in your life by helping you visualize your future.
  • One way to view your journal might be less of a narrative and more of a timeline of decisions.
