{ Week 8 } Cont. Opposite Thoughts

Sinking Ship!
What if I sink the gardens into the boat. What opportunities would present itself? How about the idea of capturing wind energy and collecting water that exists in the air already? Will see.

{ Week 8 } Initial Thoughts

In section. Folding Shell.

Form
Should be aerodynamic for movement

Wind Advantage
Form should catch the wind to convert into electricity for: lighting, communications, etc.

Rising Heat
Can be captured for electricity

Form
Core as a community space. Edges as personal spaces.

Alternative Arrangements
Creating sun opportunities. Lowers energy cost. Not sure if the air to spaces ratio is good enough?

Open End
How about creating a closer relationship between the community space to the water, situating it between the water and the land. Like a beach???? There are notions about how we would normally plan a city.

{ Week 8 } Rice Intensification and Process

Australia boasts the most efficient rice production system in the world. We create the highest yields of medium grain rice, using least amount of water (50% less). I did get this information from Sunrice though.

Another efficient rice method is SRI - system of rice intensification. Currently, we are teaching women and men in developing countries to use this method to increase yields. It is a dry method as opposed to the wet one.

I will base the form of my mobile architecture on rice fields!

{ Week 8 } Aquaponics Ratios

Pilot Commercial Aquaponics at Challenger Institute of Technology (Fremantle, WA)

Say a 5000L tank will require:
- a vortex filter system
- 1000L sump tank with submersible pump
- 16 x 6m NFT channel

Shade cloth for:
- wind
- frost
- birds

Fish Ratio
- 350 Rainbow Trout
- 35kg per cubic metre

Hallam's Aquaponics

This system uses 1 Fish : 10L water : 10 L Food  (As long as fish are growing at different rates).

So 100 Fish: 1000L of water : 1000L of food can be produced.

In another video showing a commercial crop, 1000 Lettuce can be harvested every week with 4000 Lettuce growing. To achieve this rotation, it takes 2hrs a day to harvest but I couldn't find out how many people this required.

Other Systems

I also found another ratio: 1 Million Pounds of Food, 3 acres, 10000 Fish, 500 compost

{ Week 8 } Main Components

http://aquaponicssystemplans.com/wp-content/uploads/2011/07/Commercial-Aquaponics.jpg

• Fish tank
• Grow beds
• Water pump
• Aeration pump
• Biofiltration
• Mechanical Filtration
• Plumbing for irrigation and drainage
• For media based systems, medium is needed.
• Fish and plants (seeds)
• Water

{ Week 8 } How Plants Receive Nutrients from Fish

My dad started a small patch of tomatoes a couple of years back using a similar technique to the video. Very primitive but similar ideas of using the tank of fish at the bottom as opposed to NFT which uses a nutrient film flowing into channels. Wish I had looked more closely at what he was doing at the time...

Natural Provider of Nutrients
Phosphorous, Nitrogen and Micro-minerals are provided by the fish waste as opposed to using Seasol or other fertiliser.

Additions
This system has iron deficiencies so you need to add this especially in the first year.
Calcium hydroxide and Potassium carbonate is also added. This also balances pH.
Sodium bicarbonate is a cheap option but sodium is not good for the system.

{ Week 8 } Hydro/Aqua-ponics Research

Benefits of hydroponics.

• No soil is needed
• The water stays in the system and can be reused - thus, lower water costs
• It is possible to control the nutrition levels in their entirety - thus, lower nutrition costs
• No nutrition pollution is released into the environment because of the controlled system
• Stable and high yields
• Pests and diseases are easier to get rid of than in soil because of the container's mobility

Benefits of Aquaponics

• Yields 25-75% Faster

{ Week 8 } Circle of life

Mimic natures cycles.

Produce an ecosystem?

For example, produce seaweed for consumption and use as fish food to harvest fish. Fish waste can be reused for seaweed production.

But what about plankton and other things you can't get? Maybe it should be open for any fish to come along

This is hard. Time to look at food production soon

{ Week 8 } Ship Basics

SHIPWEIGHT 9 with crack !!!

When designing and building a vessel, weight and center of gravity are key parameters for successful performance. Speed, strength, deadweight, stability and seakeeping are all parameters crucially dependent on the weight and center of gravity. To ensure and maintain these parameters a reliable estimation of weight and center of gravity followed by an organized tracking and monitoring activity is essential.
