A tower of polished black concrete cylinders covered in cables and submerged in liquid is situated on a lab bench in Cambridge, Massachusetts. They appear to be accomplishing little to the untrained eye. Damian Stefaniuk then flips a switch, though. The LED lamp flickers to life when the man-made rock blocks are connected to it.
When the LED first lit up, Stefaniuk recounts, “At first, I didn’t believe it.” “I thought that I hadn’t disconnected the external power source, and that was why the LED was on.”It was an amazing day.
We invited students, and I also encouraged professors to observe, since initially, they were also skeptical that it was effective.”
What’s causing all the excitement? This harmless-looking, black lump of concrete might be the energy storage of the future.
We can obtain clean, limitless power from the sun, wind, and sea through most renewable energy sources.
However, the wind does not always blow, the sun does not always shine, and quiet waters do not run very deep in terms of megawatts. These energy sources are sporadic, which is problematic in today’s energy-hungry society.
