GEODE (Geo Enviromental Oxygenated Deepsea Ecosystem)

This is my first ever instructable, so I apologize for the poor quality of writing. Seeing this contest, I was inspired to try something entirely new. Maybe someone else will see it and make something better with my ideas! I'm going to stop rambling now and tell you what I did. I designed a habitat capable of sustaining human life at 4000 meters below sea level. There's air, food, and most importantly, a livable pressure. This is how I did it:

• Stainless steel
• Titanium
• Pressurized water
• Breathable air
• Vegetation
• Access to Seanet (the wifi in the water)
• People
• Ones willing to stay in the Geode
• Maintenance personnel
• Thick cables
• Pumps

The blue part spins, turning the generator to make the power. The red part is a floating buoy to house the generator. The fins on the blue part must be large enough to catch ocean currents. It has a hole all the way through for the cable, this is so that it doesn't get tangled. The cable runs from the generator on the surface to the GEODE. With the power, we could also run internet down into the GEODE.

The white boxes float on the surface full of pumps that send breathable air down the chutes into the GEODE. There's a layer of 25 atm air as shown by the white ring. There are little inlets all around the base that can be opened or closed to control air pressure and airflow in the living area. The inlets send the air in a circular motion as it rises to the roof where the exhaust pipes are.

The red is solid walls, the blue is pressurized water, and the white is pressurized air. At 4,000 meters, the water pressure is at approximately 400 atm. Most of the walls (|) are 5 meters thick while the water buffers are 2 meters thick. The water pressures, in order, are 400 atm | 200 atm | 100 atm | 50 atm | 25 atm of air (1 meter), then a meter of wall, and finally a 1 atm living area. Human waste will be used to grow food.
