just like me!

yeah, they're pretty great. sadly i haven't had a good egg in a long time (farmer quit), so I've stopped eating them.

Edit: I don't really have a full answer, but I hope that we can get the problem fixed with community-based video hosting, like the one linked above.

... and even then I find them pretty bad in quality compared to fresh eggs from the nearby farmer, I must say, from my own experience.

I think it goes to the moral panic in the 1970-today. But I don't have a link unfortunately.

I'll give you a short introduction to the power grid (btw. it's called "stromnetz" (electricity network) in german). The power grid has many "levels", where each level represents a network of cables that transport current at a given, specific voltage. For example, you might have one 220kV level, and then a 5kV level, and a 230V end-consumer level.

Between these levels, there have to be translations. These are "transformers" today, transforming high-level AC into lower-level AC or the other way around. For AC networks, they are basically a ring of iron and a few coils. However, for DC networks, other transformers exists, such as Buck/Boost converter.

My question basically is: is there anyone who can give me experimental data on how well DC networks would work in practice? Personal experience is enough, it doesn't have to be super-detailed reports.

All that aside yes in the future there’s probably going to be a high voltage DC network in Europe. Less so for private consumers, at least not in the foreseeable future, but to connect up large DC consumers, that is, industry, with DC power sources. If you’re smelting aluminium with solar power going via AC is just pure conversion loss.

Thank you, that was exactly what I was looking for. I know about aluminum production processes, and that it requires large amounts of DC power.

do you have a source for that?

I know about the buck/boost DC-to-DC converters, but they don't really use AC internally.

agree

Okay, these are short term problems. "power lines as thick as your wrist" depend on the voltage. If voltage conversion works well enough, that issue disappears.

But, take note of how many DC voltages you use in your house. Devices in mine range from 3v to 25v and some weird one like 19v for a laptop.

Yeah, that's why we need some kind of standard for these things.

well, a large part why I asked the question is because I hope that somebody knows more about what buck/boost-converters can do today. I know they work well enough on small scales, but I have no experimental data for them on larger scales.

I assume they would work well, but I'd like that somebody links me to the right datasheet or something.

Edit: you have a very important point there. " Seems like the [...] voltage converter should be the prime determinant, rather than specific applications of generation/consumption." YES. So, let me rephrase my question: does anybody have experience with high-power DC voltage converters?

I'm thinking there would be a transition period, where some devices would accept AC, and the others DC.

There will be two different types of power socket outlets, and two converters to convert between AC/DC or DC/AC. (Rectifier and Inverter)

Their grass really is greener, and our local vendors should be trying harder.

My response to this is always the same: Our software is FOSS, if you don't like some parts of it, go fork and improve it yourself, instead of demanding that somebody else does the work for you.

And again, this is probably the smartest living human, has spent decades looking into it, and his result was “I dunno, maybe look at this?” So if anyone ever tries to tell you that anyone knows what consciousness is. You know they’re talking out of their ass.

As long as capitalism drives science, we’ll never know. Because there’s no money in finding it out, and we’re at the point of looking at freaking quantum wave collapse inside of neurons, it’s not exactly something that’s easy or cheap to investigate.

I just want to point out that there has been philosophy before capitalism, and a lot of clever people looked into the question of consciousness without capitalist interests. As such, a lot of modern science doesn't really focus on it; but nevertheless, there's a lot of clever thoughts about it. Like in chinese buddhism, there's views of what consciousness means in sometimes great detail that really make sense to me. Saying we don't know anything about consciousness because modern science doesn't is wrong, i think.

can’t see things when I close my eyes

I see funny patterns. But definitely no real-life objects. Kinda like on Acid. I guess that my brain naturally produces some hallucinogenous substances.

Is Everyone Conscious in the Same Way?

Nope. I am conscious on different days in different ways.

Yeah I've tried that, but the controls are sometimes less-than-optimal.

I wonder whether maybe you could attach some hardware controller to the android device.

probably minetest

yeah I've tried it, it's great :D
