Designing an innovative system for sea wave utilization
For the sea wave energy exploitation, the department of Energy of Palermo University is investigating a new approach based on the mechanical motion conversion from a linear motion into a unidirectional rotary motion. This mechanical output can be used to run alternators, producing electrical power with a very simplified energy conversion chain. First preliminary tests have been realized in laboratory using a small-scale prototype.
New solutions for energy supply: sea wave and offshore photovoltaic in Sardinia (Italy)
This work illustrates a study on the integration among sea wave farm and off shore photovoltaic in Italian island (Sardinia). In order to exploit both energy sources, the paper presents an innovative prototype, designed and developed by Palermo University. According the data about sea wave and solar energy potential, we evaluated the installation of wave-solar energy farms, based on the prototype presented in this paper.
A state of art on plastics in the oceans: Observation and Mitigation Methods
Marine wildlife faces a growing number of threats across the globe, and the survival of many species and populations will be dependent on conservation action. The aim of this paper is a presentation of mitigation methods overview about plastics in the ocean, in fact plastic pollution is increasing and in order to mitigate this problem, technology might give the solution
Energy savings for indoor lighting in a shopping mall: A case of study
The paper presents an application of energy saving in the final users. In particular, the case of study evaluates the energy consumptions of a big shopping mall, located in the middle part of Italy, illuminated by fluorescent lamps. In order to reduce the energy demand, the case of study shows a first solution based on LED lamps; a second step considers the adding of a building automation system, maximizing the energy saving, thanks lighting sensors that module the luminous flux taking in count of natural lighting through skylights.
