Innovative Water Technologies (IWT) caught my attention partly due to their creative filtration system and partly because of their endorsement by the Clinton Foundation and the "Rethinking Water" Foundation.
Both foundations have employed IWT's technology to help with the crisis in Haiti. http://www.innovativeh2o.com/HaitiToday/haitiToday.htmhttp://www.rethinkingwater.com/
The Clinton Foundation donated 5 GE Sunspring units capable of producing up to 5,000 gallons of water
per day and Rethinking Water is raising funds to install units in Haiti by advertising "A single donation of $25 will provide drinking water for a family of 5
for a year."
I happily sent off $25 and I encourage others to do the same! This is a very easy way to help out a huge number of people in dire need.
