Railroad Energy-Harvesting Tie for Powering and Charging Railway Applications

The proposed novel railroad energy-harvesting tie is capable of powering various trackside electrical and electronics equipment, including establishing remote charging stations for drones. The energy harvester tie (ETH) uses an electromagnetic generator that is coupled with an efficient motion transmission to convert the movement (kinetic energy) of...

Simultaneous Ocean Wave and Current Energy Harvesting using a Single Power Takeoff

Marine and hydrokinetic energy harvesting heavily depends on the type of Power Takeoff (PTO) that converts water motion into electricity. However, existing ocean energy converters can convert only one of ocean wave, tidal stream or marine current energy, which fails to fully exploit the potential when both energy sources are available, such as in the...
