26 innovative projects that improved the world in 2015

1. The machine that converts poop into clean drinking water

Approximately 2.4 billion people around the world didn’t have access to basic, safe sanitation in 2015, while more than 660 million people used unimproved drinking water sources.

The Gates Foundation talked to engineers to figure out how we could use technology to tackle these issues. Peter Janicki, CEO of Janicki Bioenergy, developed a machine (shown in the video above) that converts sewer sludge into clean drinking water, electricity and pathogen-free ash in a matter of minutes.

The processor can help developing countries both by providing clean water and energy, as well as employing entrepreneurs to run it in the regions where it’s needed most.
