What do you need to be virtually self sustainable on a BOAT?

[ybbor]

holy crap why didn't I see this earlier!

because this is the second tuime it's been bumped from a months-old grave

 

[Fifty]

ahh!

Well anyways it's a stupid idea because you need millions to make a platform that won't die in the first squall.

 

[Abaddon]

surely depends on the scale- a big enough capsule could outlive a wave or two.


-also, its my thread, i can bump if i want to

 

[Tenochtitlan]

Make use of hydro-power by some sort of dam.
A good agricultural and irrigational system.
A desalinization plant to sweeten the water.
Some animals if you crave meat.

 

[Abaddon]

I figure animals will be best harvested directly from the sea.

No, it couldn't, at least without millions upon millions of dollars.

 

[Tenochtitlan]

If you can get past my shi++y paint skills here is a simple idea. By being able to rotate depending on where the current is coming from, you will be able to generate alot of hydro-power. Ofcourse generators are available on all of the currents. And they are easily lifted upwards for maintenance.

 

[Tenochtitlan]

No, it couldn't, at least without millions upon millions of dollars.

Or you can choose a calm location.

 

[Abaddon]

would that not require it to be fixed to the ocean bed?

 

[Tenochtitlan]

No, just anchored. De-anchored if you want to rotate.

Name a calm location in, as slozenger wishes, international waters.

 

[happy_Alex]

has anyone suggested expanded
polystyrene?

Name a calm location in, as slozenger wishes, international waters.

I think the calmest locations are anywhere within about 2 degrees of the equator, and so some of the mid atlantic and mid pacific must fit the bill and be in international waters. Weather systems practically never cross the equator and so you'd get practically no storms or even major winds as long as you stay close to it.

has anyone suggested expanded
polystyrene?

Sounds possible. Expanded polystyrene is highly resistant to damage from sea water. Tar and organic solvents would damage it, but it seems unlikely they'd be encountered at sea. UV light causes it to become very weak and brittle with time, but presumably the sea water would protect the portions of the boat below the waterline, at least to some extent.

 

[Tenochtitlan]

Choose one of the calm areas

 

[Abaddon]

"The Doldrums" are pretty boring as far as wave action goes.

Could the expanded poly be perhaps coated in fibreglass? That would be pretty floaty and secure.

 

[Sidhe]

Choose one of the calm areas

The pacific is a good choice, the clues in the name Unless it's hurricane season , then the English channel is pretty harmless

 

[BCLG100]

sounds like an idea for scrap heap challenge.

 

[Abaddon]

haha, would be a cool show.. but how would they just its self-sustainability, or would they just test it in a lake?

 

[BCLG100]

dunno cos that fit bird would be presenting it and thats all i ever contentrate on

 

[Abaddon]

Yeah i guess- not as fit as the original presenter though


Does anyone know if Algal nets do ok in open seas, or need to be in the nutrient rich shallows?
