BUILD A SAND BATTERY!

April 27th 2024 03:00 pm @ Karakung Reef

Store Photovoltaic energy in sand with a heating coil to be dissipated later for space heat. We'll build this simple, dubious contraption together and see how it flies. No technical skills necessary.

We'll most probably be using versions of this at our HQ for space heating or for keeping our battery from freezing in winter.

at Karakung Reef / 6009 Cedarhurst (near 60th and Baltimore on the 34 trolley)
