[SpaceProgram] Fwd: Space Farmers: LEDs As Key To NASA's Permanent Lunar Life Support - Forbes

[cole santos]

I have nothing running ATM but I did a lot of monoculture algae work when I
was in aquaculture program at UH

http://contrails.iit.edu/DigitalCollection/1962/AMRLTDR62-116article03.pdf

This is where I got my ideas.

My test reactor is going to be 18" x 24" x .2"

Man sized reactor will be 24" x 48" x .2-.09 with ~20 of them in parallel.

Algae will be extracted via this device.

and o2 / co2 / vox will be monitored by sensors on arduino control.

Short term plan is to replicate the boeing experiment and adapt for longer
term production

Longer term, utilizing human wastewater as a nutrient supply and
electricity source with waterwater fuel cells.

Each project is part of a larger plan for a compact biological closed cycle
habitat.
