Michael Pritchard challenged himself to provide clean water to those who need it. Water purification devices are bulky and expensive. What if people that really needed clean water had their own way of cleaning the water there in front of them? Now they might have just that. Pritchard invented an efficient and portable water purification device. Check out this TEDtalk he gave about it.
Who wants to find out how to deliver these bottles all over the world? I do.
