ENERGYFROM WAVES AND WATER CLEANING IN THE PORT OF GENOA

Transcription

1 International Forum on intelligent energies and the sustainable development of the city and the port ENERGYFROM WAVES AND WATER CLEANING IN THE PORT OF GENOA Presented by Prof. Paul Noja - Project coordinator

2 ENERGY FROM WAVES why energy from waves? O W CM Water energy module

3 why energy from waves?

4 why sea waves? Because sea waves, if properly canalized have a ready available power bigger than other renewable energy sources, and offer more possibilities of utilization: Are typically available H24 May be used to clean port water May produce drinking water

5 o w c m project Oscillating water column motor

6 o w c m Owcm is a multiple piston engine coaxially connected with a vertical pump, which uses sea waves as propeller, utilizing the combined factors: Archimede s prinìiple Clapotis effect Waves focalization

7 o w c m The project is a spin off of an origional idea of Domenico Bozano, well known inventor of several marine systems, and it has been refined through the cooperation of a few institutional bodies

8 Fase 1 a porto antico 0,6 km working principle Clean water from open sea is pulled up to the top of the sea wall through the vertical movement of the piston (a floating device) generated by the pushing of the waves. A coaxial vertical pump attached to the piston fills a very long water tank placed on top of the sea wall, from which tank the water precipitates in a turbine/generator placed a few meters below, and from the turbine, through ducts, the water is driven in dirty areas of the port to clean inner waters

19 Sea state other sources Study from companies building marinas wave height cm days useful days days per year with waves higher than one meter

20 o w c m Owcm is a piston engine coaxially connected with a vertical pump, which uses sea waves as propeller, utilizing the combined factors: Archimede s prinìiple Clapotis effect Waves focalization

21 Archimede s principle A body immersed in a liquid receives an up push equal to the weight of the lquid it moves

22 Clapotis effect When a wave approaches a vertical sea wall its height doubles Effetto clapotis

23 Wave focalization The entrance of the water has a parabolic section which has double width of the cylinder, so water flowing inside gets a further acceleration to better push up the piston
