Dalton Bateman, in cooperation with GrooveShark and Pledge5, put together Dealtruism, an interesting project to end the use of plastic water bottles. By selling reusable water bottles that filter regular tap water through carbon filtering elements, the project intends to reduce the demand for bottled water. In addition, part of the proceeds from the sale of the reusable bottles will go to support six local businesses, including Gainesville Hackerspace.
Thanks, guys! Good luck on your project!
