For 4 years I started an investigation in the field of Ultra-Low Power (ulp) pulse motors. The first project was the Donut Motor on a 3V button cell as power supply. More motors and pendulums were made in 2020 and the technique became more refined. I started projects to run my ulp devices non-stop on solar energy. No battery, only a supercapacitor is used as energy buffer. Now in 2023 soil batteries are also used to feed my ulp devices. The soil battery endurance test is still on the go.
