Ocean Power Technologies' Autonomous Power Buoy® (APB) converts ocean wave energy into useable electrical power for remote and near-shore at-sea applications, where power from shore is unavailable or inaccessible. The APB has been proven effective and reliable in sea trials and can be tailored to meet the weight, volume and power generation requirements for a wide variety of marine, mariculture, scientific, communications, maritime safety, homeland security, and military applications.

Advantages of APB Technology

Powered by the endless source of ocean waves.
Proprietary power storage and management system allows energy
  production even when there are no waves.
Completely autonomous (independent of shore power) and not
  grid connected.
Environmentally benign.
Station keeping capability.
Oceangoing “platform” for mounting communications and instrumentation.
Accommodates and powers various payloads.
Provides a stable communications and instrument platform, including for
  cell phones, allowing “Talk on Water”™ capability.
Easily deployed and retrieved in all water depths.
Able to utilize various anchor and mooring systems.
Designed for long-term ocean survivability.
Low life-cycle costs.
