This applies to nearly all insects too. When an insect is unable to molt any more, then it usually means it’ll die soon since they can only really regenerate their organs when they molt. It’s why arachnids and crustaceans can live so much longer than most insects, because they can keep molting and hence rejuvenate themselves.

When insects injure their exoskeleton, the most they can do is exude a patchwork fix. When spiders and crustaceans lose an entire leg, they can regenerate it after a molt or two. The most primitive insects like silverfish have no metamorphosis and can keep molting as well.

It’s telling that the longest lived insects, termite queens, are protected by an entire colony and do not need to move around, minimizing the damage they sustain.

Its exact role in the immune system is unknown and it doesn’t seem absolutely necessary, similar to how people who are heterozygous for sickle cell anemia do not display symptoms because they have sufficient amounts of normal blood cells even if some of their blood cells are sickle cells.

It doesn’t scale down well. 1 solar panel can generate power, but for the CSP it needs a very large central heat engine and lots of mirrors surrounding it to focus light at the center.

It’s also very water intensive, which is seen as a waste because it needs to be put in places with a lot of sun, which tend to be dry and water scarce.

That’s called concentrated solar power, and it uses a lot of mirrors to focus the sun’s heat onto a bunch of salt to melt it down and use it to generate electricity.

Apparently its efficiency is similar to that of solar panels. But it should be cheaper since you don’t need expensive materials for all the solar panels, only normal mirrors.

It would help to a certain extent. In water, the acceleration force would translate directly to pressure such that if you accelerate at 1g you would feel the same amount of pressure as you would underwater on Earth.

So assuming you’re under a meter of water onboard the ship, you could easily go up to an acceleration of 40g since then the 1 meter depth would be equivalent to being at 40 meter depth on Earth which is an okay diving depth for recreational divers.

Yes, the radiating lines are non-sticky while the circling lines are sticky.

Also when wrapping their prey they manipulate the sticky web with their claws which are coated with an anti-stick substance.

If you were to grab a spider and just slap it directly flat onto its own web it would probably get stuck.
