Clean water for everyone may be possible

I have always been interested in how access to clean water is something millions of people do not have. I have been amazed by the fact that the basic need for water has left a large part of the world's population debilitated by cholera, typhoid, and dysentry. Water purification plants are just too expensive for the people in third world countries where most of the clean water issues are. LifeStraw technology has offered a solution to the problem. They have devoloped a drinking straw that purifies water as it is being sucked. Another similiar technology is Steripen that uses UV light to purify gathered water. I plan to use these two new technologies to introduce revolutions in clean water technology. I want to talk about how engineers and scientists are using cutting edge research to address global health concerns in innovative ways.
