Minecraft Elegance: Looting Ghast Farms (up to 7200 tears/h, 9000 gp/h, Java 1.16+*)

Looting ghast farms are highly obsidian efficient, so you don't need to build an obsidian farm in order to make a decent ghast farm. A special portal elevator for ghasts is demonstrated and can be adapted for most portal-type ghast farms. An example farm using 4 portals is shown in the tutorial, which produces 1100 ghast tears and 1400 gunpowder per hour using 364 obsidian blocks, which can be mined in less than 14 minutes with a diamond efficiency 5 pickaxe. The spawn area can be expanded up to 30 portals, using about 30 stacks of obsidian, and produces 7200 tears and 9000 gunpowder per hour.

There are reports on SPIGOT servers that ghasts do not spawn regularly in soul sand valleys, so this farm may not work properly.
On some PAPER servers, ghasts may retaliate with fireballs once the player attacks, and these fireballs may break the composters and glass in the killing chamber. In this case, replace the composters with upside down stair blocks made from a stone variant. Be sure to also spawnproof the top side of the upside down stair blocks (with a slab, for example). You can replace any broken glass blocks with wall blocks.

* You will need to add torches to prevent skeleton spawns in 1.19 - 1.19.2. Note the torches on the top of the portal frame and the torches next to the base of the portal frames.

Alternatively, you can use magma blocks as the spawning surface. Skeletons will still spawn in the portals, but will be instantly teleported away.

NOTES:
0:03 I had a cold when recording much of this video, so my voice is a little funny.
1:25 The farm could have been designed to have a spawning area under the nether roof, which would have been slightly more productive, but it comes at the expense of possible spawn potential interference from hostile mobs in the surrounding terrain and from striders in any nearby lava lakes. Construction of the portals would also be more dangerous due to the possibility of ghasts and skeletons shooting at you as you build.
4:00 If player will be flying close to the farm, you may want to cover both sides of the portal with glass so that ghasts cannot see out of the killing chamber. This prevents ghasts from shooting fireballs, which may break the composter(s) that holds them in place.
6:36 Press F3+G to bring up the chunk borders. Chunk borders are used to simplify aligning certain parts of the farm, but chunk alignment is not required, for example when upgrading a different ghast farm.
11:36 You can make your flint and steel last longer if you put more items into the hopper clock, since this lengthens the amount of time between alternating the portals. This approach is limited by ghasts entity cramming in the portal elevator if you lengthen the period too long.
16:15 Turning off the hopper clock will stop the use of flint and steel and let the farm operate without looting. Ghasts die from entity cramming in the overworld instead, and drops are teleported to the nether.
16:22 Fletchers may convert gravel to flint for you as an initial trade.
