Bill Gates, founder of Microsoft, gave a video overview of the Janicki Omniprocessor. This system takes sewage waste and converts it into electricity, clean drinking water, and pathogen-free ash.
From an input of human waste, which you could be paid for taking, you create 3 sterile outputs that you could also be paid for. It’s an opportunity for entrepreneurs but also a standard-of-living improvement for places without good waste treatment plants.
Check out the video below from Bill Gates’ own YouTube channel.
