I haven’t really seen proposals for planes that are full electric beyond just toys for rich people to do short hops but you might be right that battery planes might make sense with future battery tech. I just don’t see anything justifying it right now.
On the subject of energy efficiency though, you’re absolutely right. Synthetic aviation fuel is an order of magnitude more expensive than batteries.
I wonder if short hops in electric propeller planes are gonna take over everything in a few years. Like it will be the cheapest option for any trip under about 800 miles. Cheaper than driving, even in an electric car. A few Canadian companies are already doing this with seaplanes, where most of the trips are under 30 minutes anyway.
This tech is mature, in the US we’re just waiting on the FAA to certify it.
According to this NPR article there are 4 million flights under 500 miles in the U.S. alone. Based on my quick estimate of the chart in the article, that’s about half of the flights made. Other parts of the world may be better or worse depending on terrain, etc. The number of short flights is going down due to efficiency. They mention pilots, but everything else indicates fuel costs. If these hybrid planes took over those flights, and are as effective as projected, they could maintain equivalent or better fuel efficiency on short hop flights, making them more viable.
Now, the point about trains is quite relevant, but the infrastructure for planes is already there and I don’t see regional train routes filling that gap any time soon. This would also make synthetic avgas more viable since you would already be using less overall.
