How to make continuously running machines on solar power?
My experiments cover ultra low power pulse motors or pendulums, on solar energy with supercap storage. The size of the non-stop machines is such that they fit on the windowsill.
Sometimes weeks of cloudy sky must be bridged. Daylight has to supply enough energy from the small solar panel. A big supercap has to bridge the ‘dark times’. Also energy harvesting is subject of my research. See the atmospheric energy page.
I made more prototypes of pulse motors. The electronic circuit I use is simple and reliable.
Working in the very low power field requires a specific approach in mechanics, electronics and measurement. The rotor needs to be light and has to run on very low friction bearings. The circuit has to deal with a very low current and has to be perfect adjusted.
