OTOH I don't hate everyone who's committed a crime, and I don't think the purpose of our system should be "punish the wicked" or exact retribution or anything, either. If we think a person can be returned to life on the outside without undue risk to the public, I'm all for that. but if OTOH we can identify that someone is likely to recidivize(?), then maybe it's best for everyone if they stay locked up. Meanwhile, I don't think we can look at the penal system in isolation to determine that - see e.g. comments elsewhere on this page about the quality and capability of the society at large to provide an environment that lessens the likelihood of recidivism.

You seem to be assuming that the difference between Nordic countries and the US is only about the penal system itself, as opposed to e.g. more social democracy i.e. a stronger social safety net for people once they are back out in society, which might them less likely to resort back to crime?

"In other words, they haven't fixed the problem of recidivism, they've just kept people in jail longer."

If they're keeping the habitual criminals in prison, and it means fewer crimes committed against decent law-abiding folk, then what's the problem? Isn't the purpose of our laws and penal system to protect the innocent?

Even if battery energy density started getting close to that of liquid hydrocarbons, and thats a looong way off still, youd still need more batteries than you would fuel because batteries dont get lighter as they discharge like burned fuel does, rocket equation stuff. A 747 carries ~150k kilograms of fuel, if that didnt burn off thats an extra 37k kg the first quarter of the flight, an extra 75k kg the first half of the flight and so on...

Battery planes may never make widespread sense, if we ever start generating enough carbon free energy cheaply enough and even if all ground transport goes battery electric or whatever, at some point it might still be worth it to just make carbon neutral jet fuel with air fuel synthesis. That seems closer on the horizon than the battery tech needed for large planes to be feasible, hard to beat jet turbines for that application.
