>Comparing battery energy density to fuel energy density usually ignores the fact that combustion engines aren't that efficient.

>>Jet-A has a much lower conversion to useful work than a battery


Jet-A that has been combusted doesn't require any lift.

Edit: Since I have an aerospace engineering degree, I'll post the 100 level concept. https://web.mit.edu/16.unified/www/FALL/thermodynamics/notes...


But at the same time you had to design an aircraft to be able to shed that much weight and handle a load that sloshes around. That has cost. Again though, the core point is you can't compare directly. It is more about the final design and final purpose. eVTOL to NYC shows this. We may see quieter, less polluting cheap taxi service, basically a superior ability to function, because of being electric. If you only look for reasons it is worse, you will find them and not progress.

Given the current state of battery technology, this is probably the only possible commercial use case. Even then, you have serious limitations like low passenger capacity, takeoff/landing still requires a helipad, recharge time, and the questionable safety in the event of motor or hinge malfunction.

And once this gets in use improvements will lead to bigger, longer range, etc etc etc. Batteries too are rapidly improving and this will push more emphasis on that. The first Write flyer couldn't do much either.

Ironically Imgur bans the UK

Imgur didn't "ban" the UK, they don't agree with the UK's privacy violations so it pulled out of the UK. That's their prerogative.

We've lost control of the machines already

I was at an "AI Security" talk the other week, that centred around. "Don't trust inputs from the AI"

Well duh


I did scroll across to the UK and was disappointed that there's none for here.

But I'll probably add my own receiver soon!
