[color=#000080;]Also on Biosector01 it says that the Kanoka were activated via a pulley system, not a hammer system, so is Biosector01 wrong?[/color]
That's true; I forgot about the pulleys (lol I'm proofreading a story I myself wrote at the part where that very fact is mentioned... my memory ). Still, they would want backup motors, and there would have to be at least a switching system, and preferably at least two motors, one for up, one for down.
So, considering the pulleys, I'd say each airship would likely have one motor attached to the pulleys for up, and one for down, and at least one backup engine for each (as if up ever fails, you're basically doomed). That's four per airship, times six is 24. I'd call that the "likely minimum", then, and I still think they'd have more. That does seriously limit the number of motorboats, but there would still be more metal. Also, I recalled after posting earlier that for Ngalawa boat racing they do row.
So how about this:
Around (or less than) 24-ish boats with motors (and some of the motors be used for the Onu elevators instead). Some others of the same design for shallow water conveyed by pole, like Macku's. And any others they needed could be conveyed by rowing, like the Ngalawa racing boats.
That could result in a lot of carrying capacity, easily enough for about 333 Po-Matoran, if those on the non-motor boats simply weren't shown in the animation.
[color=#000080;]If I may go slightly off topic (if its not ok then just forget about this section), how did the airship chute system work?[/color]
I'm fine with asking this.
A portion of a transport Chute capped at both ends was built into the back of the Airship. It provided forward thrust when it let a small portion of the Liquid Protodermis that was under high pressure jet out from the back.
Now how it gets that pressure, and why a chute (rather than a tank) are the big questions that come to my mind immediately. Here's one theory that might work.
IMO, it uses a chute wall because it's lighter weight, and likely the inner cap is on a piston, so it can press inward to increase pressure. Chute walls are simply protowater -- the same thing as the fuel here -- magnetized in place. As more fuel is spent, the inner cap could push toward the back, keeping the pressure up, and the cylindrical wall would actually shrink in mass, so some of the material of the wall would actually be recycled as fuel. So the weight of the vessel decreases more with time than it would if the wall was metal. So as fuel goes down, ship loses mass, making it have less momentum and thus being easier to accelerate. The ultimate in fuel efficiency.
Whenever it completes a journey, simply pull the pressure cap all the way forward, and hook a pipe to the airship, whose other end is a spigot in the top of the supporting ring of the chute section. It would simply fill up like filling a bathtub; the magnetism would catch some of it to form the walls. Then, when it's full, the inner cap would push to the back a little, bringing the pressure up. And/or the spigot itself could have high pressure due to pumps to make it high-pressure to begin with.
[color=#000080;]And I take it its capped with a magnetic force field[/color]
Hadn't considered that. It's possible. If so, it would be even more efficient in terms of weight.
[color=#000080;]so do they open the force field a bit when they want the ship to go forward[/color]
I was assuming both caps were metal and the back one simply has a tiny nozzle in it. But yes, it's possibly they simply open a field cap a little too (maybe both, since a metal nozzle would help focus it).
[color=#000080;]Also (if I may ask) does the liquid protodermis that is let out stay liquid, or does it turn to vaporized protodermis?[/color]
My guess is it would be spread out so much by the force of the propulsion that it would in effect be vapor -- really liquid droplets too tiny to see as anything but mist. Some might glob back together, though, and rain slightly.
[color=#000080;]About the Ga-Koro pump I have a theory. What if the stalks under each of the huts are sturdy enough to support the huts without any extra support, but when the Tarakava attacked Ga-Koro it broke the stalk under that hut, causing it the sink. If this is the case then maybe the pump that Takua activated is the village’s master pump, that when activated tries to raise every hut. It could fill cavities under the huts (just like you theorized) with air, keeping those still afloat from sinking and bringing any hut that sank to the surface. Though this is just my theory, and since I still haven’t really played MNOG it could have many holes in it. [/color]
That would make sense.
Or they could have used all those Levitation and Increase Weight Kanoka to keep the lilies floating (somehow), and the Rahi knocked out the Levitation, so the hut sank.
No, Greg said that after a thousand years of use (and that would be even more use than normal), Kanoka drain entirely of power, becoming mere frisbees basically. (A corollary of this is that airship Kanoka had to be replaced often, probably in rotating arrangements to prevent an entire airship's worth going empty at the same time midflight.)
It would explain where all that Levitation and Increase Weight Kanoka went, and why we never saw them used against the Rahi. (I'm particularly thinking Nui-Rama attacks might have been stymied by such disks.)
I'm not entirely sure we didn't. The disks fired from that machine in the Le-Wahi minigame/battle in MNOG for example might have been empty Kanoka, while the Matoran preferred wooden disks. Or, they might have been used as mere disks for a while but stolen by the Rahi by the time of the Toa's arrival, and replaced with wood.
Or they might have melted them down to be various machine parts.
It's also possible that the Matoran did use them, though, and they ran out of power and/or Makuta stole them all...hence the throwing disks we saw later. But I'm not sure I buy that because the Matoran did have a year of peace and the Turaga seemed to go out of their way to hide valuable stuff like that. The lily pads would be a "hidden in plain sight" thing.
Yes, but sadly impossible, since they could not purify more proto and make replacement Kanoka. And since they were out there throwing disks of any type at the Rahi, it's inevitable that over a thousand years some wouldn't bounce right back perfectly. That trick would probably be a difficult learning curve anyways, so they probably accidentally threw the Kanoka away before learning it well. My guess is they would make some wooden ones right away, and save the Kanoka for tougher times, but since a thousand years' worth of those came and went, they used them enough to drain them, lost a few while not drained, and eventually lost them all before becoming really adept at not losing the wooden ones.
EDIT: You know, since I'm at this spot in my story and I see it included some theoretical details you might be interested in, why don't I quote that section here? I notice that in this version, instead of mentioning any backup engines I actually had a manual backup system, though since most airships were automated I would still lean toward backups that would automatically switch on (likely both). Keep in mind this is just a theory, not canon:
The airship's interior was an alien sight to Onua. It felt like being in a giant bubble [...] as it was made entirely out of a metal frame holding strong protoglass panes between the beams, other than the metal floor. But the bubble was textured by hundreds of big robotic hammers, each holding what looked like a Matoran disk, only not made of wood but some strange material he didn't recognize.
Half the disks, and the metal of the hammer-claws that held them, had the shape of a Kanohi Miru painted on them in white. These were tapping slowly right now.
The other half had a black mask shape he didn't recognize, and were not moving.
Cords from these hammers ran forward along a pulley system and met in two metal bars, one for each color, which were at the end of two machines. The right one, controlling the white hammers, was filled with spinning gears and pistons. This made the bar tilt back and forth rhythmically. When one side went taut, the hammers tapped the metal frame of the airship. When the bars turned the other way, the hammers were pulled back up. A heatstone in the center of this apparently powered it.
Two lines continued from here to a similar system with no heatstone under the pilot's chair. There was a peddle system and various levers to switch gears. [A non-canon character] sat in this seat, but didn't use the peddles. Onua assumed it was a manual backup system.
I went on to describe the tank propulsion system but actually I think I'll revise that in light of points raised here. (So thanks, this has been productive to me! )
