Hi Shane. Thanks for you comment. I received the open IDEO challenge today. I was curious at how they would engage me. They make it incredibly simple to participate. This led me to following through to submitting a concept. I wanted to make the barrier to entry as simple as possible. I would love to join in with others to see that people from all walks have clean drinking water. I believe over time this issue will grow from clean to availability. I will check out Biosand! Thanks!
