"History teaches us that men and nations behave wisely once they have exhausted all other alternatives"

"Sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs."

The Report of the U.N. Brundtland Commission, Our Common Future, 1987
"You never change things by fighting the existing reality. To change something, build a new model that makes the existing model obsolete."

SDEWES Technical visit will take place on 4th October, when we will go to the University of Palermo to see the first thermodynamic solar plant in Italy directly connected to the national electricity grid and the first Thermolytic Reverse Electrodialysis Heat Engine.

Technical visit will start after the first morning conference session on October 4th, with organized bus transportation to the venues and lunch. Number of seats is limited so please sign up for the tour in your conference Comet account. Since the technical visit is organized parallel to mid-day conference sessions, participants signed up for the tour will not be scheduled to present in the mid-day conference sessions.

Technical tour is for participants only and is not a part of the accompanying person fee. Exact schedule will be available few days before the conference. Please contact us sdewes2018@sdewes.org for all questions.

Visit to the Solar Parabolic Dish system integrated with Stirling engine

The high-tech solar plant installed at the University of Palermo, exploits the concentration of solar light carried out by a parabolic dish; concentrated sunlight heats a Stirling engine that operates by cyclic compression and expansion of hydrogen at different temperatures. The cyclic pulsation of the Stirling engine moves an alternator which, in turn, produces electricity. The dish-Stirling solar concentrator can produce electricity in a sustainable way, not requiring combustion nor producing any dust or fumes and thus avoiding any pollution of air, water or soil. The device, which achieves a global record in conversion efficiency, is the first thermodynamic solar plant in Italy directly connected to the national electricity grid.

Visit to the Thermolytic Reverse Electrodialysis Heat Engine

A salinity gradient heat engine is a device able to convert low grade heat into electricity. The operation of the very first Thermolytic Reverse Electrodialysis Heat Engine will be demonstrated. This engine is based on a closed-loop reverse electrodialysis unit fed with two ammonium bicarbonate solutions at different concentration which will convert the salinity gradient into electricity. The solutions are then regenerated through a suitable stripping/absorption process which makes use of low grade heat as energy input”.
