we cannot have private trillionaires milking "privatize the profits and social the costs"

no more, it has to end immediately

they aren't just silo-ing their wealth, they are leveraging against societies, funding far-right violent politics against society

even the evil Koch-brothers have cancer wings in hospitals around the country, Musk doesn't give a dime to charity, just his own foundation which he controls to only do what he wants to manipulate

pre-pay costs to society before damaging society

no, just no

make them pre-pay a multi-trillion cleanup and cancer fund for all the toxic waste, not just the launches but pollution burning up in the atmosphere

I'm reading about pilots spotting drones during takeoff/landing that the airport didn't know about

And I've read about airport shutdowns in UK and US without a single arrest which is why it keeps happening

So whatever system exists, apparently not good enough

if it can spot/track drones that is a marketing opportunity for airports around the world that have to deal with drone nonsense which shut down flights for days

if you aren't afraid of difficult math breaking your brain, I highly recommend this youtube channel "PhysicsExplained" (sorry I forget his actual name but he is brilliant)

he has a recent two-parter on Maxwell and electro-magnetism that are EXCELLENT

* part 1 https://www.youtube.com/watch?v=YqxrlunKCaU

* part 2 https://www.youtube.com/watch?v=wt1KJtD4Qh8

but I am not kidding about the math, he starts off slow and gentle and hooks you in, but sometimes after 10 minutes in my brain is screaming and cannot keep up

guess what, Iran will hold the gulf hostage regardless if US is there or not

exactly like the nightmare Afghanistan is for women there now left to the Taliban

regardless if US was there or not it would have happened

world is an absolutely horrible place filled with monsters

you can't say all these countries should be saved by US and then end USAID to let a million people die with food and medication already paid for left rotting in warehouses

btw we are also starving all the people in Cuba to death with an illegal blockcade since the start of the year, so why is Cuba our responsibility too?

at some point WE become worse monsters, we're at that point

there's a better way for 100% savings

just completely exit like Afghanistan

and remember all this military hardware eventually ends up in the hands of police departments domestically, next decade is going to be wild

$21 TRILLION spent on militarization 2001-2021

imagine how much by 2031, at least double

ps. they are still executing fishermen without trial off Venezuela at a million dollars a pop

sorry there is absolutely no federal agency that has not been compromised at this point

you'd have to prove to me that Russell Vought has not tampered with an agency for any statement emerging to be believed

even jobs numbers are not believed by wallstreet anymore

and surpreme court has now said only Fed is off limits to protect their own money

redo this report in 2029

like LiFePo4, sodium-ion also won't burn

ie. so the fire department doesn't have to spend three days trying to put out a Tesla fire

for long hauls, not stop and go city traffic, the weight penalty doesn't matter as much once the weight is moving

a tractor-trailer could have a huge cell behind the cab or replacement the massive diesel tanks?
ck2

that might be a evolutionary step where you just pump in electrolyte under a housing into waterproof container and every 10 years just pump it out again for fresh electrolyte

doesn't burn like LiFePo4 so no fire risks, though I am not sure what a short-circuit would do in damage/danger

why even under a structure though, just do it like a septic tank?

note sodium-ion is no longer two or three times the weight of lithium-ion, there is only a +33% penalty

apparently the problem is there is not yet enough volume in production to compete on price, which I thought was the whole point?

> sodium-ion specs have improved to the point that the technology could break into the general EV market. A recent study by Moritz Schütte at Aachen University in Germany and his colleagues found that a sodium-ion battery by the manufacturer Hina rivals Tesla’s lithium-ion batteries on most parameters, although it would still be a third heavier

> But CATL claims its sodium-ion battery has an energy density of 175 watt-hours per kilogram, which can compete with the lithium-iron-phosphate batteries in low-cost models from Tesla and others. And while sodium-ion batteries still haven’t quite beaten lithium batteries on price, that could change as they expand, according to Schütte

> sodium ions generate less heat in electrochemical reactions, reducing fire risk, so less money can be spent on cooling. They also form weaker bonds with the electrolyte, so they don’t slow down as much in the cold

Trump Inc is a white-collar crime family which is why he pardons every white-collar crime they can find

BTW you know those classified records he took to Mar-a-lago that almost put him in prison?

They were all the records about his family businesses, it's documented, they were unique investigation records and he was trying to end all investigations

Saccharomyces Boulardii is not like any other probiotic

go ask google or chatgpt to explain why and you'll get it, more than I can narrate here

it will not colonize and can even be taken with antibiotics to help the gut survive

as long as the person is not allergic to yeast they would be fine in theory

once a person stops taking it there is no trace of it in your system 3-5 days later

ps. never take multi-strain probiotics, if you think the supplement world is sketchy there is absolutely no regulation or consistency to the probiotic world
ck2

my 2 cents

1. try taking Saccharomyces Boulardii asap, it is a very different kind of probiotic, a yeast actually, that tends to push out the bad and promote the good

2. JAK-STAT inhibitors are the only known drug to get the body to stop attacking itself from autoimmune diseases, but not a cure and unfortunately they cost an absolute fortune without insurance but importing from Canada and India is possible

sure but you aren't going to help mental/emotional problems by getting stoned

there are far better, legal supplements to treat that anyway, less expensive too

dope activates AMPK in the brain/CNS and turns off AMPK in the body/heart it's an incredibly stupid thing to do to yourself (also why people get "the munchies")

literally why it's called dope (before dope meant "cool")

people just want their recreational drugs

it's as stupid as smoking/vaping and not even black box warnings will get people to stop

now if you need pain management I can respect that 100%

but you need to investigate Palmitoylethanolamide and Geraniol as alternatives

Nancy Grace Roman Telescope is also going to be amazing for raising new questions

and I hope the attempt to lift the Swift telescope to a higher orbit is successful

if you really want to stay on top of what is breaking astrophysics in realtime, I highly recommend following DrBecky on youtube or elsewhere, she is fantastic

if price is no object get the AirGradient PM2.5+CO2

but Ikea now makes the most affordable PM2.5+CO2 sensor, at $35 a no-brainer

https://www.ikea.com/us/en/p/alpstuga-air-quality-sensor-sma...

in there is a very nice/expensive Sensirion SN63C sensor that costs nearly as much as the Ikea itself

https://sensirion.com/company/news/press-releases-and-news/a...

unfortunately Ikea requires Matter network not plain wifi for communication so I've been looking for a cheap Matter hub or DIY SPR

who is rushing out the press releases with just fake news?

NASA only this past month finally did a supersonic flight with their development vehicle

they don't even have data/results yet for the "thunk" test

that's a decade away from commercial success

average person won't even be able to afford a supersonic flight

this administration is beyond bizarre, even when they aren't being destructive they are just wasting everyone's time/money
