Energy Observer: Sailing the world for a cleaner future
Issued on: Modified:
This week we bring you a special edition of Tech 24 dedicated to the Energy Observer. This ex-racing catamaran is set to sail around the world for six years solely on renewable energies. The goal is to prove that a cleaner world is possible. Before it departed on its incredible voyage, the vessel and crew stopped off in Paris for the expedition's official launch. We also look at what the French capital is doing to become a more energy-efficient city.
