SummaryThis Mason jar lid is part of a water purification system called electrocoagulation (EC). Created by us folks at elequa, it's purpose is to hold electrodes suspended in a water sample to be treated with EC, a process which can do amazing things like clarify fracking water, kill bacteria and viruses, and even turn soda pop back into water! We are just finished with designing our prototype circuitry and software and are in the process of open sourcing it. Follow along as we deliver this vital technology to the world through the power of open source!
