To put it in context, Artemis did many fully destructive tests but typically on the ground. Artemis had and spent an overhaul budget that was likely close to a hundred times that of what SpaceX is spending in today's dollars.

And even better representation, all the fully destructive tests of SpaceX have carried out have costs less than a single successful shuttle launch. And it has a much larger payload.

Even with the destructive tests, of which are planned this way, not only is SpaceX is far cheaper than any past space program, they are advancing fairly rapid.

Balloons are open. Most typically do not expand but the excess air just escapes out the bottom. Basically they will rise till the overall weight matches that if what they displace.

There are more efficient balloons that do expand and can attain same great heights. Far more than conventional aircraft even. But that expansion is mostly due to excess material in the construction and little from stretching. Thus the pressure difference is minimal while the volume increase significantly with altitude.

Comments are correct here with one missing high level component for routers. That is the very top level routers are designed for tier 1. I started an internet company and we got large enough to decide to become a tier 1 provider. There is one big difference in this configuration is that we publish our own blocks of IPs and we listen for published IPs. We have routers that essentially maintained a list of where all the IPs or block of IPs worldwide needed to go. More importantly, I would send out a list of my IP blocks that would propagate across all the tier 1 routers across the world. That could take an hour but more likely minutes.

Having this allowed me to essentially connect to the internet at zero cost. There is some cost to be assigned IPs but I was trusted. While I say zero cost, I still had to pay for large bandwidth dark fiber to new York or other major meet me points. I also had to pay rack space to put a tier1 router into these buildings. But what is really gives me is the ability to have multiple connections to the pipes and because I publish my own IPs, I can balance all the routes and other providers can find the best way to me thru a process called weighing. Also if I loose a connection which is rare at this level, I could rapidly and automatically republish my route on working connections and usually within 15 minutes, all the routers in the world would know. 15 minutes actually is likely long. These days 5 minutes.

Now the interesting part of this, I publish my own IPs. I have to be extremely careful as with a single stroke, I could say I own all the IPs to China. Well likely a few strokes. I certainly could make a simple mistake and take control of a shit load of IPs. That means suddenly traffic could come to me that was destined for another country. More correct, because they are publishing, it would just make a mess and take some IPs down. If I publish a big block in China, I would essentially DOS myself because the pipe sizes I buy are factors smaller. Now this is a trusted system because we all connect together randomly. There is and can not be any central control as we all need to publish freely for this to work. But if I were to screw up and say divert a shit load of IPs destined to say Washington, it would rapidly be figured out and I would rapidly be determined to not be trusted. I would be shut down physically at some point.

Essentially I have fairly normal routers with one feature that allows them to dynamically keep track of all the routes worldwide and to periodically publish all the IPs I own.

A better question is, would more houses get built and if so, who would build those houses? If not, and there are more people needing houses than houses available, do you not think that the extra money would mean people would be willing to pay more?

Talk about inflation spiral. lol

Who opens them up exactly? And that person who invests in a restaurant will leave some other job resulting in that much less product being built this something rises in price somewhere.

Rent caps just result in less people or corporations investing in rental properties. If you are alread have 90 houses and 100 people want to rent, how does caps encourage more houses?

At the end of the day the only thing that matters is how productive we are in total. Anything that is scarce will be high in price and if you mandate a lower price, then some people will simply not have shelter if you want to use that example.

AWACS had parachute and some chut you could slide out at one time. Don't quote me on that entirely. They simply were not worth it. First most accidents happen and have happened on takeoff and landing. No good in that situation. In a war environment, getting hit by a missile, pretty much the only weapon that will take down an AWAC or similar. Missiles likely won't give crew time to escape. Plane will be doing some kind of tumble. Then you got training. It not simply train once and all good but every year. Sometimes it is better to use that money and time to provide better alternate training that will be more effective. Say for more escort aircraft or better alternate safety systems within the aircraft. You also have the space it takes up resulting in less functionality of your aircraft.

In a large scale world war III scenario, AWACs and similar would be a dangerous plane to crew. Shot down rapidly. In our current warfare situation, they are one of the safer planes to be in. Unless you are Russian and incompetent.

Lemmy is pretty caustic platform if someone doesn't agree with you.

Oil and gas is massively profitable. Western nations have crippled that industry resulting in countries like Russia becoming energy giants. The world is consuming new records in consumption this year and let capita, developed nations are nearly a factor more then emerging nations.

I work with a few hundred businesses and most have a good idea and know their product well. The majority that fail do so because of the administrative business side of things. Billing, expenses, tracking inventory and costs. A good idea is only half the work.

Don't be discouraged but ensure you keep an eye on the business side of things. Beyond that, some of the suggestions here are valid.

Mostly corruption and stability doesn't allow for business to develop along with the wealth that brings.

There are other factors but mainly you need good governance and free markets to allow for wealth creation. It at least that is the only model that has worked so far.
