[Bioconversion] Soap Bubble Greenhouse

[jason marshall]

It doesn't seem like growing algae would be something desirable,
unless algae is what you're trying to produce.   It'll reduce the
growing capacity of the greenhouse, and I believe there's some danger
of pump fouling anyway.

I was wondering why they made such a big fuss about their bubbler.  I
wondered why they didn't use a conventional bubbler, or even an
ultrasonic device to make fine bubbles.  In the latter case, it turns
out that soap in the water keeps the fogger from fogging.  I'm not
sure why they couldn't hook up a bunch of aquarium bubblers with air
stones, though.  Seems like it would have less trouble with
degradation by the surfactant (one of the things they complain about
as causing their prototypes to fail in the long term).
