If voting was limited to property owners that have individual economic agency not being dependent on earned income, like it was in the old days, democracy won't be threatened at all with periodic, normal and unavoidable economic crises, and these crutches supporting capitalism won't be needed.
Just take inflation. It is utterly irrational that inflation causes political upheaval it does. Because it is economically neutral - it's simply a convenient tool for the crooks to manipulate the masses by brewing their anger. If only the economically independent property owners could vote, inflation won't be a concern at all and economy could develop a lot better.
People around 60 are perhaps the most reasonable - they remember enough of Communism to know it's shit, and they've been politically active when Russia had actual electoral politics during the Perestroika and the 1990s so they value freedoms they lost, and they had enough of experience with consuming competing manipulative narratives to understand how easy it is to bullshit people.
> we can average over a week because we may assume 2 hours' storage (so for 100 GW nominal, 200 GWh) and that's about 4-5 worst days in a row […] because storage over even longer periods is unrealistic
I don't see any particular logic to either part of this.
Better question for "realistic" storage is how much do people actually want to spend, how do the costs change as quantities scale up from hours to days to weeks to seasons. (4kW * 24h * €50-€70/kWh) / 10 year battery life from daily cycles is an unsurprising part of a monthly energy bill (especially as this would basically substitute most of the grid's role in the hypothetical where Germany for whatever reason wasn't still buying nuclear power from France etc.); pumped hydro is estimated around €100/kWh installed, but different maintenance cost and lifetime.
> Now electricity consumption is about 10TWh a week. Which means, 35x
9.3, I think you're using old numbers.
I find no search results for 280 GWh claim; I will assume the number itself is correct, but given the rate of growth of PV it is of material relevance which year this happened in, e.g. if that 280 GWh was in was in 2020 it's more like 18x, if it was in 2015 it's 13x.
> with the average solar park density of 1 MW per 7.3 acres
You're double-counting here.
33.9 W/m^2 with 22% cells means the capacity factor is 15% of the name-plate capacity. This is a standard value in much of the world, varies from about 10%-20%, you can't do better than about 32% from anything fixed to the ground even on a completely clear sky on the equator. The map I linked to already accounts for all of that stuff, it's *internal to* how they reach the ~1000kWh/m^2/year for the worst bits of Germany: https://upload.wikimedia.org/wikipedia/commons/1/19/Germany_...
Anyway, point is 1 MW/7.3 acres *already* accounts for "winter is bad".
> This number can be slightly improved by installing panels over the angle that optimises performance in winter
Opposite error! Not when you're talking about covering an entire country it doesn't. Panels would shade each other.
> and also in the fact that solar park is not fully packed with panels because they need pathways to service them and they need to not shade one another
And again, now you're double-counting. Precisely because 1 MW/7.3 acres number is already accounting for gaps, you've mixed up the optimal output per m^2 of *panel* with the optimal output per m^2 of *land*, and it's land that matters on this scale, the optimal number per unit of land is what you get from laying the panels flat on the ground.
>For direct land use requirements, the capacity-weighted average is 7.3 acres per MW, with 40% of power plants within 6 and 8 acres per MW.
And no, 280 GWh was literally a week ago: https://energy-charts.info/charts/energy_pie/chart.htm?l=en&...
So we need to consume 10 TWH a week (consumption particularly for week 48, same one), and we produce 280 GWh with 100+ GW of installed capacity. Which means, we need 35x if only power is concerned, and 205x if all energy is concerned, not just electricity.
