could someone explain to me how that $5 spend is lying to me. i know elec is cheap, but that cheap?
eliben•37m ago
During certain hours of the day in California, electricity is essentially free due to solar overproduction, which sometimes causes negative wholesale prices.
cj•33m ago
I've never quite understood negative electric/gas/oil prices.

Are you literally paid for agreeing to receive the energy?

vlovich123•28m ago
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.
eliben•28m ago
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).
robin_reala•24m ago
Yep. Last August the total cost to charge my car for the month was -10SEK of about -$1.05 US, as my energy company was trying to put load into its batteries at the times when the grid most needed it.
twoodfin•36m ago
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 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.

> 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).

vel0city•25m ago
At 120 miles of useful pure electric range, I can't imagine there are many US corridors where that pure electric range makes sense. That's still a range where the door to door time of a car can still win. I wonder why they don't push the idea of it being a hybrid more, as it seems to me a lot of useful routes are going to rely on the generators.

I'd love to see something that can do around 250mi. It would be nice to electrify transit in the Texas Triangle if we end up never being able to actually build useful HSR.

I wish them luck on continuing to try!

Island hopping is the usual sales pitch for these planes.
mikeyouse•18m ago
As someone who lives in the Great Lakes region - there are a ton of 100 mile flights that would take 4 hours to drive - often as the first leg in a two-flight trip. Also places like Denver -> Ski resorts (Vail/Aspen/Crested Butte) are 2 - 3hr drives, heavily dependent on road conditions all within the pure-electric range.

See also: Boston and NYC to Cape Cod and the Hamptons.

The electric/green angle helps with these kinds of routes too.

nradov•17m ago
The best use case might be short flights over water or other geographic obstacles where driving routes might be much longer or impossible. Like Kahului Airport to Ellison Onizuka Kona International Airport for example.
Aboutplants•21m ago
VTOL aircraft have the same distance capabilities and make more sense in a lot more scenarios than this, with way more flexibility. It’s obviously larger but I’m just not sure of potential advantages over other modes of transport currently available and in the near future
spongebobstoes•15m ago
could we relax the security around electric planes, because they don't carry as much highly explosive material?

that could make it much more convenient and appealing as a travel method

hollow-moe•11m ago
Nope, because we all know about the race to the bottom of all companies and the littlest crack or wiggle room will be used to save a penny and kill people.
