Especially I recommend this UN report of Spirulina:
FOOD AND AGRICULTURE ORGANIZATION OF THE UNITED NATIONS – A REVIEW ON CULTURE, PRODUCTION AND USE OF SPIRULINA AS FOOD FOR HUMANS AND FEEDS FOR DOMESTIC ANIMALS AND FISH
Why are they all shaped like tiny corkscrews? Do they actually have motor skills and swim around by rotating?

>Spirulina microalgae and new generation PBR Yes they can rotate and swim. But mostly they use their gas vescoules to move in water up and down like submarines.
One of OP's links shows a video of a homemade-looking cascade made of several cut plastic bottles. It stood next to a sunlamp and you could see tiny algae growing through the flowing water, that was pumped continuously by some water pump. That's neat. Reminds me of the WindowFarm project from a few years ago, where you could make an aeroponic garden and hang it on your window.
I wonder how efficient this homemade algae grower would be as a food source.
