The EDF Group is committed to French and European start-ups to promote innovation in the service of energy transition and new electrical uses... This sped up the development of projects such as Echy, which captures the sun's rays and redirects them inside buildings, DAMAE Medical, which limits the use of skin biopsies with a non- invasive medical imaging system, Energiestro, which stores solar energy from a flywheel made from a high-performance concrete, and Wandercraft, which allows people with neuromuscular disorders to walk again via an exoskeleton.
