Scientists who accepted the Bill & Melinda Gates Foundation’s challenge to reinvent the toilet showcased their inventions in the Indian capital Saturday. The primary goal: to sanitize waste, use minimal water or electricity, and produce a usable product at low cost. India is by far the worst culprit, with more than 640 million people defecating in the open and producing a stunning 72,000 tons of human waste each day - the equivalent weight of almost 10 Eiffel Towers or 1,800 humpback whales.

New Delhi (AP) — Who would have expected a toilet to one day filter water, charge a cellphone or create charcoal to combat climate change?
These are lofty ambitions beyond what most of the world's 2.5 billion people with no access to modern sanitation would expect. Yet, scientists and toilet innovators around the world say these are exactly the sort of goals needed to improve global public health amid challenges such as poverty, water scarcity and urban growth.
