Looks like good sci-fi there. Not to nitpick, but where's all the water come from?
Like I mentioned, there's a way for regular old boats to even reach the island via upward waterfalls and air-foils/parachutes/water-wings that catch the upward flow and use the negative force from the pulled water to propel upward. Think of it like using umbrellas shaped like wings catching water to use as ballast and a means of lift (some upward winds also contribute). For descent, same parachutes have a vented duct that can control the flow to continue catching water, but also let more out safely to descend in a similar manner; come and think of it, I want to make those boats now to show how they'd work. Anyway, said waterfalls are filtered through the land in a contained aquifer, acting as a filter, which can also be purged by either pulling up freshwater lakes or using surplus water within other aquifers to clean the main one of the salts and impurities collected. Of course, there are also distilleries within the main infrastructure that can also cleanse the prime aquifer of impurities and extracting the island's primary export, salt, which can also be blessed for magical purposes. Explains the water income for the residents, as well as financial income via trade. Just as well, seeing as it's a really big floating island, and it can navigate while at it, it can also be piloted towards clouds, and thunderstorms, and in case any typhoons or hurricanes are a threat to the island, the island can avoid them on the whims of the high-councils that are the central government of the island (In case of droughts, or farmers need a boost (water from the clouds and enrichment from lightning), find a nimbus-cloud to fly into).
Can I use that image of the floating island? I want to put it in the OP for Land of the Sky.
Go ahead. Floating islands, especially of such scale, I don't often see anywhere, and are a challenge to make look right.
Great drawing and idea... and the melee idea actually physically possible; the right airfoil with a forward shaped wing can indeed spin like a boomerang and still fly. Ok if I add a small flying model of this to the 'to attempt' list of mad things?
I want to see some of these ships made in X-Plane or any flight simulator to see if they would actually work (flying normally, and spinning). You may get sick when it spins. I can try, but I'm still new to 3D modeling, plus coding them would be a bit of a pain. Boomerangs aren't the only melee bladeships either (SEE: Kunai Drop Pods in an earlier post; 3D render provided). Basically, I've attempted to translate as many melee weapons into ships as I could think of. Some needed some creative control to make them look less like their weapon counterpart to render them more aerodynamic for flight purposes (not all craft have Star Wars repulsor lifts), while still having weight balance well enough to still be a contact weapon made for ramming speeds, including capital ships as a last resort. Of course, for the sticklers, they do have guns on them just in case ramming or melee fighting is too impractical (more than already noticeable).
EDIT:
Oh, right, you can build some of these things. If you can make a practical version of any of my creations (given current technological limitations), that would be awesome. Hell, anyone have a 3D printer to make any of my 3D models, I'll be willing to even pay to have them tangibly produced and sent my way. I mean, some of my creations would be model-kit worthy, if I knew how to produce them properly, and a way to dis-assemble them model-wise so we can assemble them physically.
