Well it was sort of related with all of the god trolling.

Bonus points for the picture with the greek quote "If god is almighty then is he not able to slay evil?"

"If he is not willing then is he unkind"

And so on...

Pic unrelated.

People died from drinking too much water. Your argument is invalid.

Infinity is a concept rather than an empiric value. It is theoretical. Think of it as "as far as you can go". If you go your farthest, and make one more step, "as far as you can go" is where you are.

That's fun, but you still need to get to the space station.

>>1039302

That sucks.

A launch loop. Where? The Sahara desert?...

What else to do with a huge sandbox?

This thread is now about renewable and cost effective orbital stations.

Before finding a destination, we should first ensure we are capable of getting off this planet.

Hm, first stage space shutle thrust required is 1,225,704 lbf.

Current typical bimodal rocket engines output 15,000 lbf.

Perhaps we are getting ahead of ourselves in designing a ship capable of space travel AND landing capabilities.

... Yeah.

NASA is experimenting with a quartz honeycomb structure for heat shielding...

Not from heat but from physical damage.

While this craft uses a different kind of atmospheric navigation )spoiler), thermal energy from atmospheric friction could be an issue.

... I was having vision of glass-coated aerogel...

>>1039101

I'm guessing that it would be possible to protect the aerogel using some kind of highly heat-resistant material. Tiles are too brittle. Electromagnetic repulsion could also be used on the shell to protect against space dust.

I propose a dual-mode propulsion system. An onboard bi-mode nuclear reactor could power nuclear pulse propulsion and be used for atmospheric or strategic maneuvering to burn a bimodal rocket system.

The nuclear reactor could generate thermal and electrical energy to help sustain life support. Using conventional membranes, CO2 could be removed from the atmosphere and oxygen could be replenished from water electrolysis. There also must be a way to remove carbon from CO2.

Waste management could be as simple as the current technologies available on shuttles.

For landing I recommend a Harrier-type of thruster/gear system, using the hydrogen/nuclear rockets thrusters.

The construction of the ship would likely have to be twin, mono-piece shells with a regenerative buffer between the two. You'd like to avoid space dust creating holes as much as possible, so a regenerative bullet-proof glass-like mechanism could be alright. Carbon shells are conceivable.

Depleted uranium is a conceivable radiation protection material and aerogel could be used for thermal insulation of the avionics and the cabin.

This design does require fuel cells to be present for thrusters.

I have no idea how much all of this would cost...

I don't really want to hire stupid people.

If I remember my paper...

There are two principal ways to achieve nuclear fusion. The first involves a toroidal reactor, the second involves pellets of deuterium/tritium blasted by a laser.

The reaction can be achieved, however it is not currently sustainable and it is not currently efficient. The toroidal reactors can successfully form a plasma from the deuterium/tritium, but the fusion reaction is not sufficient to be self-sustainable.

Lasers are not efficient. It takes much more energy to get the reaction to work, than the reaction generates.

Hm, no. 1 = 1,

.9999... is asymptotic of 1.

Well in a black hole matter is deconstructed, and the "elementary particles" are spewed out somewhere else.

It's theorized that our universe came from a "mysterious spew of elementary particles". That's why I'm theorizing that the universe as we describe it is more like a single grape on a vine, or a cell in a larger entity.

>>1024598

No, this actually occurred to me sometime when I was trying to sleep.

>>1024522

Clever, but that's not what I wanted to hear.

>>1024541

This is what I wanted to hear.

The glass is either half full or half empty, depending on what happened to it.

An empty glass that was filled to its half is half full, a full glass that was emptied of half its content, is half empty.

For one, waves and currents.

This is the ocean, not an aquarium.

A Canadian company had devised a boat to extract the oil from the water in a very efficient way. The oil floats, and their procedure involved taking a barge equipped with an inverse funnel and a vacuum. The oil remained trapped in the funnel because the water level was higher. It could've been extracted after.

Sorry for my crappy drawing.

>>1024471

I will answer that question, but I would like other people to be able to have a shot at it.

>>1024441

No, it is one or the other.

The hope that someday someone like me will be able to GTFO allows me to live, somewhat.

Assume for one moment that this glass' geometry is perfect, and contains an amount of fluid equal to half the volume of the glass.

Is the glass half-empty, or half-full?
