The concept is to build roads out of hexagonal plates of transparent hard material (tempered glass) with built in solar panels. You can also incorporate heating elements and LED lights. Buried alongside such roads could be a new energy grid, for transporting all that solar generated electricity.
Here is the vision as presented: With such solar freakin’ roadways we could generate much, if not all, of our needed electricity. We could replace telephone poles and hanging wires with buried lines, and upgrade our energy (and even information) grid while we’re at it.
The heating elements could melt ice and snow, removing the need for plowing or salting roads. Potholes or other damage could be easily repaired by simply replacing the hexagonal units, one at a time, as needed.
The LED lights could be programmable, so that all road lines and traffic notices could simply be programmed in, and changed as needed. Parking lots could adjust spaces as needed – making bigger spaces or adding or removing handicapped spaces based on demand. Recreational areas can also be programmed to be different kinds of courts as desired.
Pressure sensitive plates can also be added, allowing for the road to light up, for example, when an animal is walking across the road, providing real-time warning for drivers.
This all certainly sounds great – just like the roadway of the future you always imagined, maybe even better.
OK – now here comes the skepticism. First let me say that I like the concept, and I’m glad some some research funding is being dedicated to this idea. I also have no problem with privately crowdfunding the idea. If people want to invest in this, go right ahead. I wish them well.
But this is also a good time to consider all the possible roadblocks (pun intended) and potential problems with such a technology. I am just going to list my questions:
