that's not at all what i said, i don't see why you're so angry

the long work weeks we have today is because more work can be done.

in medieval age, you had to sow, half a year later you had to reap, and in between maybe idk milk the cows, though that takes a few minutes a day, not much longer. so they couldn't work more, because it simply wouldn't have made sense. That's why they didn't work more, not because they didn't need to.

fuck don't do this to me - i was so shocked when i saw this, i thought "oh fuck what happened here? have i really been gone for this long? has trump released a new law that all messaging boards must now be ultra-capitalistic?"

IIUC, it’s variable D/C which must be regulated and/or inverted to A/C involving more hardware, conversion, and waste.

Actually, I had a discussion about this with someone who really knows this stuff recently, and we figured that the inversion process isn't actually that inefficient. The efficiencies achieved are often >95%, so there isn't actually a lot of loss.

yes, and more importantly, normal Hydro plants could be updated to release water at selected times, to create "on-demand power". The energy is stored in the water behind the dam. So conventional, already-existing hydro dams can perform a two-sided function: Storing water, and to release it on-demand. Like a battery that is refilled by nature.

My idea is that most Hydro-Power plants can be used as reservoirs with little modification.

And biomass can be burned at whatever moment you like (provided you have the plants to do so), so it is "on-demand power" in some sense.

 

Renewable Energy has many parts, and some of them can do jobs that others cannot do. It is important to work together to bring the best renewable Energy to the world that we can hope to achieve.

This diagram represents a short overview over different elements of a renewable energy network, and what the different parts can do, and what not.

For example, Hydropower can be both an energy source (flowing water through a turbine) but also a means of energy storage (by keeping the water behind the dam). Renewable Biomass can be stored well, but can also be turned into a renewable source of energy. Batteries can store energy well, but cannot produce energy.

I guess you should do what makes most sense to you.

There is no such moral obligation as to "have children" or "don't have children". The choice should be yours.

"TOTAL LACK OF RESPECT for the Earth and the secrets that lie beneath the surface" had me for a moment. great comedy, lol

  • non-urgent computing (AI training)
  • non-urgent transports (i.e. construction material)
  • steel, aluminum production

The thing I heard is that geothermal energy is actually only renewable on geological timescales, i.e. not really "renewable". It's just that there are very large reserves, so it's not immediately obvious. But I can't find a link rn.

It's a conundrum, because while biofuels are expensive, there are ways to make them significantly cheaper, for example refining organic garbage and waste into fuels.

The dissemination and distribution of solar power might seem minor today, but if you model solar growth as roughly exponential - as is typical for new developments - then solar could become the dominant power source in 2036 - which is not far into the future, even on human timescales. I ask you to keep your head up high, and believe into the future, because I care about you, and I don't want you to suffer from depression and anxiety.

Sources: solar energy growth and energy mix

two signals drive the human spirit: positive and negative vibes.

while at first glance, both might seem like legitimate ways to actuate people, one (negative) is devouring, the other (positive) is enhancing. that is why positive news should be preferred here instead of negative ones.

I'm saying this because I see a lot of very dystopian headlines being pushed around here.

(while at first glance, negative news might seem to get more attention; in the long run, positive news is what sticks with people. be encouraging, not discouraging.) :D
