Yeast driven Calc reactor???

[Tactstat]

""Wowzah, absolutely.... My friends and I have been working on developing such devices the last couple years....! Ours also have an in-tank pumping unit (to a skimmer) a dentrifying bed (in media we cast...at the bottom middle), a yeast-driven simple calcium reactor, and a mechanical filtration area last... the middle with a light over it continuously, growing.... Caulerpa!

Found this on Wet Web Media, anybody know anything about this?
It sounds really intresting!
I am already trying to plot how to do it!

Thanks,
