near the Leaning Tower, Giacomo became interested in the cooling issues of space systems. His third year at University marked the beginning of a journey that took him to CEA Paris Saclay, MIT in Boston, ESA in Bordeaux and Thales Alenia Space in Cannes, ultimately leading him to design the smallest cooling circuit ever conceived.

and environmental issues are becoming increasingly more important, Tethys has created a personal cooling system for the well-being and comfort of individuals that can be integrated into the lining of a suit jacket, personal protective equipment, a uniform, a bulletproof vest and more. The system is designed to help those who work in extreme environments finding comfort and accomplish their work tasks.

Today it is about a person, tomorrow it is a city and the day after the planet will be concerned.

into the lining of a jacket to cool the human body in summer and warm it in winter, providing an elegant and comfortable solution. They are composed of a microfluidic water circuit that controls the interface temperature of the user through heat exchangers and thermoelectric modules. A pump ensures fluid movement to the heat exchangers, that cools or heats the human body according to the user’s chosen temperature.

Subsequently, the fluid is pumped to the condensers. The condenser system is a network of active exchangers where thermoelectric modules pump the heat from the fluid to the external plate of the circuit. Here, radial fans blow ambient air to cool the module. The cooled fluid returns to the pump and the circuit starts again.
