It's not just batteries. The entire tech stack is a huge tailwind
- autonomy
- motors
- power electronics
- sensors
- chips
- composites

🛸 Zipline launched drone delivery in Austin this morning.
@Zipline is private. It publishes no fleet count. But every aircraft it flies has to be on the U.S. registry, and the registry overwrites itself every day.
We keep every copy. Here’s what it shows:
3,009 Zipline aircraft registered today, up 110% since March.
432 more registration numbers already reserved. The next wave, in public view.
406 of 429 aircraft were on file before the @Uber deal was announced.
Meanwhile, valuation talk went from $7.6B to about $20B.
If you invest in autonomy, drones or logistics, this is the kind of signal Terminal is built to find.

top 10 fighters by useful sustained / supercruise speed:
mig-31bm — m2.35*
f-22 — m1.7–1.8
typhoon — m1.3–1.5
rafale — ~m1.4
su-57 — ~m1.3
j-20 — ~m1.2–1.4
f-35a — ~m1.2
gripen e — ~m1.1–1.2
su-35s — ~m1.1
f-15 — ~m1
*with afterburner
people underestimate the compounding effect of battery densities
with even a conservative 3% a year 250 mph ++ could be feasible for short distances much sooner that you think for a 2 seater
couple that speed with increasing autonomy and your radius increases seamlessly unlocking new lifestyles

Just a day later and now Javier Milei is offering full Argentinean citizenship with residence and passport for $350,000
Countries will keep plucking out the high skilled and wealthy from around the world for better conditions elsewhere
Which is easier than ever especially in Europe
This isn't new of course, this is what the US, Canada, South America and Australia did for centuries to attract people
It's why there's Dutch dairy farmers all over the world because many got poached in 1950 after WW2 to migrate elsewhere (and often get free or cheap land to farm on)
which would you pick for hypothetical

at 3020ft most of the time now , weather is just a bonus
our first @p2pplane will cruise around 8000ft
nice way to spend 30 billion really, even if blue origin is not as efficient
much better than a think tank or ngo
Blue Origin is great and if we had nothing to compare it with, we'd be incredibly impressed with what they built, having raised just $30B.
But let's just use BO to put SpaceX's capital efficiency into perspective;
— SPCX invented the orbital class reusable booster
— flew + landed it like 650 times
— built Starlink; 10M+ customers
— built Dragon; launched like 60 humans to the ISS
— got ~95% of the way to making a fully reusable Starship operational
— acquired xAI, positioning them to do Starmind
All of this on just $10B worth of private equity
Like what the fuck
the alia's L/D of 17 is nice but takeoff roll must be >1000 ft
rise of EQS like planes youtube.com/watch?v=zLFILxL1…
