@TechConnectify great to see a new video from you!

For some use cases, such as personal aviation, ye olde 4-stroke engine is not very likely to be replaced by electrics any day soon (unless someone invents a really lightweight extension cord). For these, synthetic fuels would probably be the most environmentally friendly solution.

Have you ever seen any research into turning excess solar power into e-fuels? The hard part is probably not the chemical or the physics part, but making the process economically viable with just excess electricity. That said, it might just be the stuff to fill a gap in the transition.

The good news is someone just made oil a lot more expensive so more people may realize that cheap fossil fuels are not a given.
