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.
solar PV → heat pump → water heater; direct, no A/C or intermediate components. Practical? Feasible?
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.
- 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.
actually, that's not true. I built a hobby-grade hydrolysis machine in my garage for a total of $3. I can't imagine hydrolysis machines to be significantly expensive in general.
The reason why they're expensive today is because they're completely over-engineered. But that's not physics' fault. It's just someone seeking the "highest-quality product" instead of one that makes economic sense.
Just informing you: You can see the power output of PV panels by looking at the Watt number. It says something like 400 Wp (Watt peak - i.e. Watt under direct sunlight). Voltage is more or less irrelevant.
translation: "dear boss, i can't come to work today, because we have 20cm of snow".
billionaires are a cancer of society and need to be cut out. they think of nothing but their own growth and will damage all of the system because of it. we need to get rid of them before it's too late.
Edit: better yet, we need policies that disencourage their behavior.
solar energy is the cheapest form of energy at this point. capitalism will drive the green energy revolution forward from now on.
