ben cohen joins us right this minute from santiago, chile. ben, we all looked at this and said, gosh, what a simple idea. what made you think to put it into production. >> one of my classmates in calculus at georgia tech, he was watching the aftermath of the haiti earthquakes. they had water but couldn't get it to the people. coil tubing has been available for many years and he said why can't we use this to set up supply lines as opposed to ship in water bottles over and over with a helicopter. >> is your biggest worry like a kink in the hose? can the hose get blocked somehow? >> this is a material that's already used in pipelines all over the place. there shouldn't be any different challenges they haven't run into. >> how many communities have you been able to affect with this thing that you guys have created? >> we're meeting with mayors near chile and rural communities bringing this to folks who need the water. currently they have a lot of trucks that go back and forth to bring water to these communities and we cut out that batch process.
