There are a lot of purported uses[1] for algae. The OP talks about oxygen generation[2] and food[3]. I've personally been really interested in cultivating algae as a source of carbon neutral jet fuel[4], specifically for personal energy independence. And, finally as fertilizer[5]. I haven't had time to do any experimentation yet but I'm excited to see that a DIY approach is so accessible.
