... Sol.Ex, the French autonomous solar glider
2022/10/24 ... At the origin of the Wings for the Planet project, Jean-Baptiste Loiselet developed a glider equipped with solar cells allowing its autonomy on take-off thanks to an electric motor powered by a Li-Po battery (lithium polymer). After a successful tour of France this summer, the engineer plans to develop a two-seater glider to continue exploring combined energy solutions ... A day of average sunshine easily offers one to three take-offs and the battery allows for 60 kilometer motor operation. For the Tour de France 2022, the pilot flew three to five hours a day, knowing that "in a pure glider, as long as it is daytime and there is wind, the flight is unlimited", recalls Jean- Baptist Loiselet ...

Lockheed Martin Flow Batteries Are Growing Up & Taking Over

US Army Tests A New Flow Battery From Lockheed Martin
2023/01/03 ... The US Army is testing a new flow battery that can suck up wind and solar energy like a high tech vacuum.
Flow battery technology is very different from conventional lithium-ion batteries. Flow batteries deploy the ability of two specialized liquids to generate electricity when they flow adjacent to each other. The setup mainly consists of tanks and pumps, which can be easily scaled to fit various applications. Fire hazards are practically zero, and the battery solutions can consist of nontoxic and abundant substances. Typically — but not necessarily — the solutions are separated by a thin membrane when in motion.  Flow Batteries Are Growing Up & Taking Over  More flow battery activity is taking place in the stationary energy storage area. In addition to smoothing over gaps in the availability of wind and solar energy, stationary flow batteries could be used in tandem with other clean technologies. In Scotland, for example, researchers are demonstrating a tidal energy and green hydrogen system integrated with a flow battery ...
