[Digestion] Solar powered toilet

[eric roy]

Hi Everyone,

I was wondering if any of you have seen this system and can comment on it. I find it very interesting on how they're using some sort of electro-chemical cell to sanitize the supertenent outflow for water-reuse.

Do you think they're cycling salt water through out the system? or fresh water? 
How expensive and reliable this type of fuel cell is? I thought it was pretty cool, and would love to learn a little bit more about it. If you know more about this system please let me know.

Cheers
