3D printing has excited a lot of us with its potential for unchaining people from the products that make it to the mass market. The idea could have an interesting impact in developing countries as the technology matures. Now we’re seeing evidence that it might save energy, too.

Solar water disinfection can be cheap – just leave a clear plastic bottle of questionable water in the sun and it will be potable within a few hours. The problem is knowing when, exactly, the water is ready. This WADI device solves the issue by measuring the solar radiation hitting the bottle to estimate when the water should be disinfected.

Coca Cola has a legendary worldwide distribution scheme and it has been on development professionals’ radar as a powerful partner for years. This idea has merit for its link to the company alone, if not for its intrinsic value.
