Berto Aussems is the owner of this website. My experiments cover at this moment ultra-low power pulse motors and pendulums on solar energy with a supercap buffer. Also low-power earth batteries are made/tested to power the windowsill size devices for a long time.
Sometimes weeks of cloudy sky must be bridged. Daylight supplies enough energy from the small solar panel. A supercap has to buffer the ‘dark times’. Also energy harvesting is subject of my research. See the atmospheric energy post and the soilurine battery post.
