Love this initiative, it s from 2 (dutch) guys, www.jointhepipe.org, and it benefits in 2 major ways. First, with the money raised from selling these durable plastic bottles they install pumps, wells and other water projects in Africa and Asia. Second, it saves the planet from drowning into an ocean of plastic water bottles. And they also created water carafes for the restaurants and tap water stations for parks and public spaces. Brilliant!!
At http://www.jointhepipe.org/ you can get yourself such a "hot" bottle.
