/diy/ - Do It Yourself

Floating halfway between the surface and the ocean floor, anchored by steel cables in water 500 feet deep, the Mark VI would be positioned on the periphery of the gulf stream so as to sap energy from the currents via it's pivoting turbine, but not be subject to significant stress on the cables. The panels around the bottom of the shaft are passive silicone membrane CO2 exchangers; They refresh the air inside without using any electricity.

Of course the plants help too, but it doesn't contain nearly enough to do the job without external support. The enclosure itself is 1 atmosphere (due to the depth, which insulates it against storms) contains a closed loop biosphere to provide the hamsters with food (plants, insects, seeds) decompose their waste, and by way of one of those tacky little multi-tier faux rock indoor fountains, a source of fresh water (passively desalinated by equipment in the lower half of the enclosure) that does not sit stagnant and allow insects to breed therein. Suspended from the top of the fountain is the artificial sun; A heater bulb, as used in incubators, provides heat and light that simulates natural sunlight exposure. Around the base of the fountain you may notice openings for various webcams that transmit live footage of the habitat interior over the internet.
