Updated Vehicle Handbook in the works

[Condottiere]

1. We're going to have powerful enough engines, up the technological tree.

2. There may be a way to minimize the effect, through hull configuration.

3. Or pop it early, with some form of super cavitation.

4. Who knows?

5. Speaking of vacuum, maybe you can eject or create vacuum in front of the craft, or lower the atmospheric pressure, which should increase the threshold for the creation of the boom.

It would vary per world, no? Depending on UWP Atmo rating?

 

[Geir]

Couple of things:
One, which marketing genius decided to call a company trying to make a relatively quiet supersonic jet 'Boom.' ?

Two, Gen-5 fighters can supercruise at supersonic speeds, but they don't do so over populated areas, so capability and regulation aren't tied to anything other than location. In many places, supersonic speed would not be allowed, in others... nobody would care. That doesn't mean you are limited to the slower speed, except there's no point in making it powerful enough go that fast if its designed as an urban commuter- why waste the money on the fancy engine? So there are choices and limits - the current spreadsheet also hardcodes some of the book rules to keep open frame and open-topped vehicles from exceeding subsonic, at least in an atmosphere (well, obviously because sound... oh, never mind you get it)

Third, same goes for stealth (even though that's not the topic) those same fighter fly with those lens-thingies on so they don't go invisible to traffic control except when it's enemy traffic control...

If you can't outrun a missile, make it more difficult for it to lock on.

The engineers wanted to call it 'Moob' but the marketroids got cold feet.

 

[Condottiere]

You're looking at a a very limited market niche.

Military applications may be the only way out.

Top speed on a 1985 Ferrari Testarossa was 181mph. Almost nowhere on Earth can you actually use all of that speed, due to laws or road conditions, but the point is that they are still available to buy and legal to operate.

So another one of those things from a different thread that I'm trying to sneak into the infrastructure section. Mostly stolen from ideas from the Isaac Arthur arcology tab (though I don't agree with his 10,000 square feet per person living area assumption. Anyway, here's an excerpt - essentially at TL12 there is zero difference between a biosphere space and an agricultural zone, and that's intentional. Feel free to poke at my concepts and math:

I like this a lot. Don't forget the superior option for us bleeding edge people.

Haven't forgotten it. Just looking to where it makes sense. Things that top off at advanced at TL12 or below, probably won't be candidates or there would have been a TL15 option.

Understood and thank you.

 

[Condottiere]

Living accommodations tend to be a question of tolerance, convenience, and expectation(s).

If I lived on a space station, and didn't like my quarters, and I could afford to move somewhere more preferable, the only thing that might keep me there is the salary, or that my significant other doesn't want to.

This probably needs labor and energy inputs as well. At TL 7- it is assumed to be open-air farming, with sunlight providing the energy, but TL 8+ with multi-level hydroponics there need to be grow-lights and pumps to move the water around -- and energy input (for the machines and basic plants) is unlikely to go down as TL rises because the plants will require the same amount of energy, water, & etc.

Higher tech gene-engineered crops might give better yields and have lower labor and energy costs -- but that would be true even if you flung the seeds out the window on a TL-0 world.

I object to using square meters instead of cubic meters. Cubic meters I can turn into Dtons, square meters I cannot. I can fit square meters within a single piece of paper, but I can't fit a plant within something as thin as a piece of paper.

To be fair, area is how crops are measured, not volume. It's the cultivated space, not how tall the plants get.

That's why I did both - square meters is fine and required for outside, 4 Spaces = 1 dton for inside.

I should add the power for hydroponics at the very least - in my head I was going back and forth on it wondering if the waste heat could cover the input needed for the grow lights. But that's probably a bit too perpetual motion.

Remember that you can have too much of a good thing. I assuming the outside versions rely on animals to soak up excess oxygen. The space station version may eject or somehow store the excess oxygen if the agricultural zone produces more than enough.

Excess Oxygen plus hydrogen fuel in a fuel cell equals power and potable water.
