Our project is non-profit meaning no-one gets paid, but I usually just myself contribute to the budget of new parts. You can view some videos here in the channel, this prototype is most promising as it solve the gases exchange and light distribution problems in the old generation pipe or flat panel type reactors. As the layer of algae is only about half centimeters max so the light is distributed optimal levels at every cell and at the end of the every pipe as the algae falls a little, it is like a small waterfall where gases exchange efficiently.
