> It uses electric motors for zero-emission short hops up to 124 miles and backup reserve generators for an extended hybrid range up to 300–500 miles.

I was wondering how they're gonna deal with alternate airports and "fuel" reserves, but it seems they also have generators on board (supposedly used in case of emergency / unplanned detours).

could someone explain to me how that $5 spend is lying to me. i know elec is cheap, but that cheap?

During certain hours of the day in California, electricity is essentially free due to solar overproduction, which sometimes causes negative wholesale prices.

They’re using wholesale prices. The entire flight was 27 minutes, peaked at a megawatt of power, and a wholesale megawatt-hour is $40-50 these days.

I've never quite understood negative electric/gas/oil prices.

Are you literally paid for agreeing to receive the energy?

I tried to run a napkin calculation, and that 5$ figure must be quoted per seat (30 seats). And a 'first flight' might be very very short, like 15 minutes of flying or less.

Yes, if you’re a battery in the system. Basically discourages generation because there’s too much supply. But this generally doesn’t trickle to consumers afaik.

Yes. Counterintuitive, but it make sense when you take all the factors into account (such that completely shutting down and then later restarting turbines may cost a generator more than paying someone to take power off their hands).
