do those orbits get larger over time?

Yes, I think they do.

I think that expansion doesn't increase distance, but velocity between objects (or so was my interpretation back when I looked at the formulas). That means that moving objects speed up over time. As such, orbital velocities increase, too, and that lifts their orbit - similar to when a rocket on a closed orbit propulses forward.

But I might be wrong; I feel 70% certain about this one.

Why not build them at the Sun-Earth L2 Lagrange point?

I don't know why I just read "UNIX" in a french accent.

I do wonder why people buy smart TVs instead of getting regular displays together with a Linux PC.

yeah i know i was joking

maybe it wasn't a good joke ^^

Open means "uben" in german so

Free Libre Open Source Software is FLUSS in german and that roughly translates to "fucking" and I think that's beautiful.

Yeah but the babies were small, which is what matters here.

The thing with eggs is that they would probably have to be huge. I guess that the egg would maybe have to be 10x the size of the finished baby (Idk for sure though) due to inefficiencies in the food metabolism. While for chickens, that's not a problem because the babies are small, for humans it would be difficult.

 

... and we know how the game ends, right?

 

As we all know, AC won the "War of the Currents". The reasoning behind this is that AC voltage is easy to convert up/down with just a ring of iron and two coils. And high voltage allows us to transport current over longer distances, with less loss.

Now, the War of the Currents happened in 1900 (approximately), and our technology has improved a lot since then. We have useful diodes and transistors now, we have microcontrollers and Buck/Boost converters. We can transform DC voltage well today.

Additionally, photovoltaics produces DC naturally. Whereas the traditional generator has an easier time producing AC, photovoltaic plants would have to transform the power into AC, which, if I understand correctly, has a massive loss.

And then there's the issue of stabilizing the frequency. When you have one big producer (one big hydro-electric dam or coal power plant), then stabilizing the frequency is trivial, because you only have to talk to yourself. When you have 100000 small producers (assume everyone in a bigger area has photovoltaics on their roof), then suddenly stabilizing the frequency becomes more challenging, because everybody has to work in exactly the same rhythm.

I wonder, would it make sense to change our power grid from AC to DC today? I know it would obviously be a lot of work, since every consuming device would have to change what power it accepts from the grid. But in the long run, could it be worth it? Also, what about insular networks. Would it make sense there? Thanks for taking the time for reading this, and also, I'm willing to go into the maths, if that's relevant to the discussion.

 
 

Hey there, I wanted to make a meme to clarify what the "grindset" actually does. It grinds the human to dust.

With "grindset" I mean the "hard-working" mindset that lots of people in the US seam to have.

I think it's very unhealthy, exhausts the body, and should be avoided. People should make a living with less than 50 hours of work per week.

 

scene from Ice Age - No Time For Nuts (2006)

it is a dystopian future where we technologically advance the planet to a state where there's no oak trees anymore. the above picture (supposed to be utopian) always appears dystopian to me, so i made this meme.
