That's an idea, and a pretty simple one too. Thanks.

The holes do not overlap when rotating the (blue) inner hull. This way 
you can position the holes in non-overlapping circular paths. Of course, 
you loose the view to the outside ;-)

As long as OS is 64 bits, no problem.

Note that Windows 32 bits can manage at best 3.5GB of memory, and that 
applications are allowed to have at most 2GB of private memory, IIRC.
(hence probably the comment about linux being better... for 32 bits, but 
it 's only a small improvement, as it is 3GB instead of 2GB)

Or you could make it as a "Dauerluft" (venting slot) with different 
number of slots.

My latest render. I'm satisfied with the inner/outer hull viewport area.

I think now it is time to consider propulsion. A nuclear pulse drive 
like Project Orion could work. I would have to model some shock 
absorbers, and the pressure pad would need to be flat instead of 
parabolic (or not?).

I'm actually not sure what my other options are.

To reflect light to the agridomes, a set of flat mirors is probably the 
best solution.
You don't realy need to concentrate the light, there is no athmosphere 
filtering it.
It's easier to orient flat mirors as needed depending on your 
orientation relative to the sun or nearest star.

I got some very good suggestions in this post:

https://forum.geogebra.org/viewtopic.php?p=139143#p139143

The problems now are that:

1. Should I collect the light from the direction the ship is heading, or 
extending from the rotating ring? The ship will not be facing the sun 
100% of the time.
2. I'm running out of room to place the mirrors.

I tried turning on the atmosphere and area light in my latest version of 
the spaceship interior, but after 10 hours the render was at 8% and 
hadn't reached the slow bits yet. I will try again in 10 years. :(

What size of area light (in term of row & column) did you try ?
(did you try a preview with only 2x2 area lights, to get an idea of time 
to render ?)
What option (adaptative ? +AM2 or +AM1 ?) are you using to speed up area 
lights ?

Place the mirrors on pivots, with some actuators, mounted on rails that 
run the length of the hull.
That way, you can place the mirrors in the most effecient way.
