I grew up in a house that was "green" before "green" was a way of life. It was an earth-berm home, southern facing, and designed to be energy efficient before energy efficiency was a global concern. My dad said that he plotted the land for two years before even breaking ground to get it at just the right angle and he did a lot of the design work himself. In the early 1980's, solar cells weren't great, but today it would be possible for a 1000 square foot house to be almost self-sustaining on solar energy, depending on location.
As we move into the internet of things and the growing digital divide, Harald Haas has a prototype of a solar cell using existing energy to stream videos at a speed of 50 mbps. His
Ted Talk from September of 2015 shows the possibility of using LEDs and solar cells to move from Wi-Fi to Li-Fi.j
What could that mean for learning? What could that mean for people who are in isolated areas of the world? What could that mean for closing the digital divide? I am anxious to see what the answers to these questions are!
