The necessity to improve the security of fishing's crew during their work can create a favourable condition to produce electrical energy. This solution to problem can do with a system that balance the forces induct from the sea to the fishing vessel. This device in this action generates electrical energy.

This article presents the result of an experimental meteorological buoy designed by the Department of Engineering of the University of Palermo, characterized by low costs and great versatility, and equipped with industrially certified measuring and detection instruments. This buoy can measure the parameters of the water column and continuously transmit the data to a remote acquisition centre. Maintenance requirements are very limited.
