Modeling a Wave Energy Harvester for Supplying Data Buoys

Applied Sciences
An energy harvester scavenging the kinetic energy of fluctuating waves for supplying small sea monitoring buoys is studied and tested. The harvester exploits a magnetic cylinder that rolls on a track due to the pitching motion of the buoy.

A Harvester with a Helix S-Type Vertical Axis to Capture Random Breeze Energy Efficiently

Micromachines, 2023
Breeze energy is a widely distributed renewable energy source in the natural world, but its efficient exploitation is very difficult. The conventional harvester with fixed arm length (HFA) has a relatively high start-up wind speed owing to its high and ...
