I'm going to go with a pre-owned Tesla. When it was new, it was 115K, but since it was pre-owned it will only be 72k. The good news is that all pre-owned Teslas get a new battery. So the car might be 5 years old, but the battery will be functional for a long time.
Keep in mind you have to hire someone to come out to the house and install a special type of charger because the wall plug isn't that great. So you're looking at an extra 1,500 out of pocket.
Its really not that expensive when you consider how insanely fast these things are.
Your train of thought seems to have derailed here. Care to explain?
Operating at a pressure 10 trillion times higher, the pumps on a hyperloop, if they use the same power per volumetric pumping rate, could handle leaks 10 trillion times larger (in mass flow) at the same power as your system. You just MIGHT want to take this into account.The accelerator I'm working at currently has a vacuum of 10^-13 millibar, so yes, that is a lot better than 1 millibar, but then it is underground, at controlled, constant temperature, much smaller in surface area, and it does not have heavy vehicles moving inside. It still takes a LOT of energy to hold that vacuum.
You have not provided any good argument supporting this slander.The prototype of the hyperloop they showed and the claim that it could produce more energy than it itself needs by placing solar panels on the outside is a complete pipe dream. It's only purpose was to get attention and investments for the name Elon Musk. He sells his name that is his main strength, and for that to work he needs to draw attention.

So, what was this subsidy Paypal got? I remind you he DID make a bundle off that, your false belief that he was not involved notwithstanding.

While Musk has a big mouth and he dreams too much, I really do not get the hate against him. Oh, wait, I do. He is successful. That's why.

Well, they're putting the Falcon 9 1st stage through its paces to gather data. Tonight's reentry was hot. It's been a while since they've toasted one this much.

And to the people saying rapid rocket transport won't happen:
It has just made its way from Florida to Africa in 20 minutes.
All right, gentleperchildren, let's review. The year is 2024 - that's two-zero-two-four, as in the 21st Century's perfect vision - and I am sorry to say the world has become a pussy-whipped, Brady Bunch version of itself, run by a bunch of still-masked clots ridden infertile senile sissies who want the Last Ukrainian to die so they can get on with the War on China, with some middle-eastern genocide on the side

Like everything it's always "Within # years" BS
No it won't happen

Liquid propellant rockets don't typically have any aluminum in their propellant. There is sometimes a minor amount of aluminum in the pyrophoric ignition fluid (which often contains triethyl aluminum, TEA). Solid propellants do (and chlorine), but high flight rates will not occur with solid boosters, they're just too expensive.
Which reactive gases? LOX/hydrocarbon engines do run a bit fuel rich, so they can have H2 and CO in the exhaust, as well as some soot for RP-1. Are these what you are thinking of? They tend to oxidize when the exhaust plume its the air though (although that may not be effective at high altitude, where the exhaust expands and cools too rapidly.
My guess for the largest unavoidable impact of high flight rate rocketry is deposition of water in the stratosphere and above. The upper atmosphere is very dry, so this could have a substantial effect at higher flight rates (10s of thousands a year or more).

You should see what happened to temperatures in America after 9/11. I believe the average temps dropped and rose 1-3 degree C because of zero air travel, in a day.
Even depositing CO2 on a commercial scale in the upper atmosphere is non trivial. It doesn't really matter if it is carbon neutral on balance because if my earth science serves me once you get to a certain altitude the churn between the layers of the atmosphere is quite small.
The whole problem with the world is that fools and fanatics are always so certain of themselves, but wiser people so full of doubts.
