Mr Wojciech Gelmuda has developed a battery-free carbon monoxide detector using Figaro's carbon monoxide sensor TGS5042. He employed some Peltier modules to obtain energy from the temperature difference between ambient air and tap water to power his carbon monoxide detector.

Due to his very unique and forward-looking challenge, his project won in the International Element14 energy harvesting design contest.
