Searching for an application for a new solar panel technology developed by le Commissariat à l’énergie atomique et aux énergies alternatives de Grenoble « CEA tech »

Fictitious scenario:

It is now possible to take a shower on the streets of Grenoble, thanks to a concept that is both innovative and environmentally friendly. This simple initiative offers users access to a heated space for just a symbolic euro, where they can shower, perform their toilette, and even charge their mobile phones. This self-contained booth addresses environmental concerns by heating water using the COSTECO thermo-electric system and using the generated energy to power the entire shower. As for hygiene, everything has been designed to ensure a clean and welcoming environment: the Cleany booth is automatically cleaned after each use, and the wastewater is filtered and reused for watering nearby plants. Initially designed for urban areas, this project aims to serve a variety of audiences, with a focus on the homeless, travelers, and people in transit. The first prototypes have been deployed in partnership with SNCF, near the central station in Grenoble.‍

Technology for a more environmentally friendly future:

This project relies on the COSTECO system developed by the CEA in Grenoble. These showers are fully autonomous, thanks to thermo-electric technology based on cogeneration. A set of mirrors reflects photons onto an absorber, thus producing hot water, around 360 liters per day, as well as energy. Each booth offers an average of ten showers per day, and the generated energy is sufficient to make the system independent of external energy sources. Additionally, an outlet has been installed to allow the daily charging of approximately forty mobile phones.

A manifesto project:

This project highlights a crucial issue of our time: the transition to renewable energies. Our planet shows signs of depletion, with Earth's annual resources being exhausted eight months earlier this year than the previous year. It is imperative to rethink our world and our technologies to offer an alternative to the constant growth in our society's energy demand.
