Air Transport to the seasteads is going to have to be some sort of VTOL, or perhaps V/STOL.
How many usable V/STOL planes you know? osprey, harrier. none of those are available to common market (military stuff) and cost as much as a clubstead itself. So that leaves seaplanes, helicopters and airships. At my knowledge airships dont necessary need a runway, just a anchoring tower. offcourse they are prone to hard winds and storms when anchored and not inside hangar. Helicopters are very expensive especially in long distance and their range is limited. Given your information about landing conditions seaplanes would need breakwater, which is expensive and hard to operate. Allso breakwater goes against the idea to minimize wave interaction.
At my opinion if we operate inside EZ (200nm) helicopters are the easiest way. They are expensive, but relatively easy as long as we find crazy enough pilot to do seaplatform operations. In bluesea operations helicopters are guite much out of guestion, unless we plan routes so that we are within helicopter range. Seaplanes are not good in bluesea operations either, because first big wave will damage seaplanes. Seaplane is little bit misleading name, because most of seaplanes are designed to land and operate in still water (coasts, lakes, rivers). Which leads to that at my opinion airship/blimp is the best option for bluesea operation. There is only one problem nobody builds anymore passenger size airships except for some very large experimental cargo blimps. So either we customs desing and build blimp or try to convince someone to start production again.
This offcourse leads to that airsupply is out of guestion as main supply/transport method and should be reserved for emergency/special-situations. Don’t try to fight gravity, it’s the law. which means it’s much cheaper to use water transports.

Allso one interesting thing a have thought about is using seastead as observation platform. Highseas are one of the darkest areas in world, so light waste won’t be a problem. Seasteads are larger and more stabile than boats, so it might be possible to get one stable enough to use it as an astronomical observatory. Only negative side is that you would be in sealevel, so you would not get benefit of thin atmoshphere as in mountain top observatories. so atmosphere would be dense and humid. plus side would be, that you could move it around so you could get it to good observation points.
my studies have shown, that humidity will be large problem. so on platform observatory might be impossible, but people have experimented and used balloon telescopes. Seastead could be used as a base for a balloon telescope in the middle of the high seas. Hydrogen for the filling of the balloon would be easy to separate from sea water, but would take guite much energy. Another mighty idea (which is allready in use) and very is a profitable business is spacerocket sealaunching. allthought sealaunch company bankcrupted. offcourse this would need special seastead, which could not be used to much else. Offcourse you could have one at the edge of seacity and float it to safe distance for launch and move it back for launch preparations.May 18, 2008 at 2:17 pm #2062
to make windmills completely useless stead would need to move at the speed of the wind. which will not happen because big structure like stead makes large drag. sure wind pushes stead a little, but stead is very heavy and its wind profile guite small because of spar compared to its weight. in fact to make wind more effective mover, I think we should consider using sails or kites as moving method. offcourse it cannot be only method and them would need to be connected low on the structure, so that they would not tilt stead.
On mill desing i comp thebastidge. vertical mill are better on such close quarters space as stead. there is a design of vertical mills, that are basicly noiseless. http://www.quietrevolution.co.uk/ .just have to look for model that is rugged enough to stand storm winds.April 28, 2008 at 5:46 pm #1909
Iam not any marinetime engineer, but at my knowledge that would be very hard and costly to build. everything would not only need to be watertight, but all so pressure resistant and everything outside would need to be seawater resistant. Allso mechanical failure while underwater is even more catasthropics than when on water. Somekind off underwater exit at the bottom of the platform could be usefull.April 26, 2008 at 10:07 am #1898
well astrobiology basicly studies life on other places than earth in the universe and the reguirements of life. astromer side of the job is not very much interested about practical biology. There is usually both biologist and astronomers in research team, so if we need to know about biology stuff we ask them.April 16, 2008 at 5:05 pm #1763
good idea, probably the best way for this kind of project. This way you get peoples special skills in use. there are people with very varying special interest and knowledge here, so why not get it in good use. Missinformation is allways a problem, but this can be countered with basic science methods. Researches must be reported and archieved in proper way, so that other people can check them. Offcourse this requires some efford and studying in scientific methods.
ps: for marketing, etc. purposes. these are not very pretty, but i made a model of seastead based on andrews blueprints. it is far from ready and rends are guite ugly. anyway anyone who wants is free to use as long as source mentioned. allso .blend file available if wanted. http://users.utu.fi/ajtaka/blender/
