It is possible to get >100% from solar + batteries. All energy needs can be handled using only a small fraction of solar radiation reaching the planet’s surface

That said, using it in aircraft (and a number of boots/submersibles) economically is an unsolved problem, but many other places can use it.
- adrianN 1y agoUsing it in aircraft cheaply is an unsolved problem. We know how to turn CO2 and water into jet fuel with enough energy input. It's just an order of magnitude more expensive than the fossil alternative.
- Lightkey 1y agoWhat a koinkidink, I just saw a news about a research platform for exactly that (okay, it's for ships but still) starting now, with the idea being to use surplus offshore wind electricity which otherwise would go unused: https://www.dlr.de/en/tt/latest/news/2025/synthetic-fuel-from-the-offshore-wind-farm https://www.dlr.de/en/tt/latest/news/2025/synthetic-fuel-fro...
