In this instructable we will go over how to construct an at-home version of a photo-bioreactor which will use solar energy and artificial lighting wit...
The over all shape of the photo bioreactor is inspired from a previous project I had been working on where it follows a mean summer solar path of the ...
I considered using two materials for the support system. I tried clear acrylic so as not detract from the function, which would be the algae tubes co...
I wanted to use a closed loop system where the algae would travel constantly and safely without getting contaminated, so using clear acrylic tubes was...
The trouble now was to sort out the frequency and amount of tubes per rib. I needed enough to cover as much of the surface as possible in order for th...
With the ‘above ground’ part of the model completed, it was now time for the plinth to be constructed which would house all the mechanisms that would ...
After that the plinth was ready for painting, a clean white look turned out to be the right choice and a color scheme of white, natural ply & clear pr...
With the plinth drying it was now time to seal the tubes and the hoses shut to make a closed loop bio-reactor. I used the super-instant glue rather th...
A minor adjustment had to be made to the pumping mechanism. Due to the fact that the 4000 Liters per hour was significantly more powerful than the 15 ...
After letting the glue settle for 40 hours, the first test run with still water was extremely successful. The air bubbles traveled at a steady pace th...
During the building period, I had started to grow algae using the simple method of a water bottle, algae food & the sun. This proved successful in the...
I let the algae run in the bio-reactor for 10 days and achieved excellent results. Perhaps it was the location of the model posistioned against a wind...
Being an ongoing project I do not have the algae biomass output of this experiment yet. I will keep you posted through my tumblr blog http://thealg...
