Low-power IoT devices can harvest energy from wind, heat, and solar sources, and you can store that energy in a battery or a supercapacitor. With help from Eaton, James talks in this episode about what electric double-layer capacitors (EDLCs) are, considerations for when you'd want to use them, and a small demo where we harvest solar energy into a supercapacitor to drive a Raspberry Pi Pico W.
