0. IIRC, most filters don't work very well without a pressure gradient.
1. How does water get circulated to clean the clean area? It will be extra gross the first time anyone goes #1 or #2 it in without any particular way to make it clean. Yuck.
2. How then will this "filter" surface clean itself on the outside?
3. Who's going to maintain it? The website doesn't specify that.
4. Is this a free public use pool? It doesn't say that it will be free.
3. Is this a utopian project cleantech scam that will be debunked by Thunderf00t soon?
