Solar cells are not the only form of energy
harvesting that can be used. It’s also possible to
harvest power from radio waves, kinetic energy,
piezoelectricity, heat energy, or other ambient
sources (see sidebar).
We hope you enjoy building this weather
station, and we hope you’re convinced now that
battery-free electronic devices are possible with
intermittent computing! Of course this is just a
beginning. Battery-free remote control? Battery-
free stock price display? You name it! We would
love to hear about your experience and your
ideas. Please send all of them as Github feature
requests via github.com/TUDSSL/BFree/issues.
