After getting feedback from the class on our filtration system it looks like the need is more in collection. That is quite understandable; we could build the best filter in the world but it is just going to sit there if there is no water coming to it. Besides, Bio-sand filters are a well known technology and the Power House could easily build one themselves rather cheaply. Looking into collection systems has been interesting and fun. There are a lot of really cool precedents out there from small scale dew collection on spider webs to man made structures like the inverse pyramid WatAir (personal / family sized dew collection) to the designboom rain collection skyscraper.
There are some really cool collection possibilities out there. I'm sure we'll come up with something great. This weekend will be hectic with a day long skill building event at the Michigan Clean Energy Venture Challenge on the agenda. Updates with how that goes soon! :-)
