The app, which now has 5,000 users, also allows everyone, with one slip, to condemn or applaud the policy carried out.

Sweetch Energy, a start-up from Rennes, is an offshoot of CNRS projects on osmotic energy. Kesako? Water always passes from the less concentrated medium to the more concentrated medium, in salt, for example. This is what causes the exchanges between the cells in our body. But extend this effect to large amounts of water, in estuaries, between a salty arm of a freshwater river and the sea, and you can recover energy. Whether mechanical, by capturing the movement of water to turn the turbines (low efficiency), or even directly electrical, by capturing the exchange of ions (charged particles) between the two media, through specific membranes. With its osmotic power plant projects, Sweetch Energy could develop additional electrical power. In France, the total potential would be 1.25 GW. But in South American countries, on the Amazon River, the supply of electricity can be more than 100 times greater.
