Lack of Fossil Fuels

How do we cope if fossil fuels take too long to come back and we are reduced to late 1600s-era technology? Would we be better off this way in terms of lessening the effects of dysgenics?

It's amazing to me that Australia still hasn't capitalised on its massive uninhabited desert areas by mass building solar panels to make an absolute killing in the green energy sector.
Literally some of the best real estate for renewables in the world and they can't pull their finger out and get it done.

Solar panels degrade so you'll need to replace them about every 20 years. The energy density is also very similar to farming, which is not conducive for radically improving wealth per capita. People also like to use energy at night so you'll need serious battery installations in conjunction, which degrade quickly too.

Baseload power is the most effective and reliable strategy, which means nuclear if you care about greenhouse gases.

20 years is an underestimate. The industry standard is 25-30 years and there are people who still have their panels after 50+ years. They don't degrade nearly as much as you probably think either. They lose about 0.5% of their rating each year, so they only lose 15% of their energy production over their lifetime. As a bonus the production, recycling, and replacement of solar panels guarantees jobs in proportion to our energy needs. Furthermore, multipurposed land can greatly reduce the land area devoted to power production, and some applications like agrivoltaics (pic related) can increase the efficiency and lifespan of solar panels by keeping them cool.

Nuclear is not an unlimited resource and in my opinion we should save it for space missions.

There are 166 numbered boxes. You have a set amount of points that increases with time at a fixed rate. You can use 100 points to use a fair RNG to generate 10 numbers and the numbered boxes are uncovered. You can use 30 points to generate 3 numbers to do the same. If the RNG chooses a box already uncovered, you regain 5 points. You can use 300 points to uncover any single box of your choosing
What is the optimal strategy to uncover all boxes in the least amount of time? How many boxes should you have uncovered before you start using the single box uncover at 300 points?

I ran the numbers and unless my maths are wrong then the optimal strat is going for the 10 box rolls until roughly 4 boxes are left.

Basically I guess that the odds for not getting a new box would be (I haven't done actual maths in a while) on a parabolic incline (I came up with this: [-(y^2)=(1-x/166)*-10000]) where and the equilibrium would be around the 5 box mark, where the odds of not getting one of those 5 boxes with 300 points (3 x 10xroll with 5/166 ~ 3% chance of getting one for a 1 box roll, and since you get 30 box rolls the figure for 300 points would be about 90%, but accounting for the 5 point gain from duplicates you'd save more points here as well).

So even though this isn't exactly the most mathematically correct strat because I haven't included the 3x roll the optimal place for considering the 3 box rolls or 300 point loss is roughly 4 boxes or so.

Can you solve this enigma?

For simplicity, say the average relative density of oxygen is 1.00.

Add one carbon atom and you have Carbon Monoxide (CO) with a relative density of 0.98. Carbon Monoxide it lighter than air.

Add a second carbon atom and you have Carbon Dioxide with a relative density of 1.60. Carbon Dioxide is much heavier than air, and drops like a stone to ground level.

Why does the first carbon atom seem to have a relative density of -0.02, while the second carbon atom has a relative density of 0.62?

No, I am talking about air in our atmosphere.

Nitrogen and oxygen are the baseline of relative density. I gave oxygen a baseline relative density of 1.00.

Carbon monoxide is lighter than air. 0.98 relative density.

Carbon dioxide is heavier than air. Relative density is 1.60.

Why does a carbon atom have a relative density of 0.48 in the carbon monoxide molecule, and a relative density of 0.60 in the carbon dioxide molecule? That is a 25% difference.

Its not a troll thread. It is just a question. But the real purpose of this post is a psychological experiment; to observe the hostile and degrading comments of so-called scientists when someone asks them a harmless question!

Did you ever wonder why the nonsensical "Galen's Humors" and "Miasma Theory of Disease" were taught in medical schools for centuries? Didn't anyone suspect they were bullshit? Of course! But people find criticism and hostility so unpleasant that they will go along just to get along.
