Boston Dynamics, for another, now makes robots that can climb, crawl, jump, and hop, and all while carrying heavy loads (some bots can manage over a hundred kilograms of weight). These “Sherpa-bots” can traverse boulder-strewn hillsides, balance on sheets of ice, and even jump from the ground to a rooftop three stories up.

Currently a billion people lack access to safe drinking water, and 2.6 billion lack access to basic sanitation. As a result, half of the world's hospitalizations are due to people drinking water contaminated with infectious agents, toxic chemicals and radiological hazards. According to the World Health Organization (WHO), just one of those infectious agents — the bacteria that cause diarrhea — accounts for 4.1 percent of the global disease burden, killing 1.8 million children a year. Right now more folks have access to a cell phone than a toilet. In fact, the ancient Romans had better water quality than half the people alive today. So what happens if we solve this one problem? According to calculations done by Peter Gleick at the Pacific Institute, an estimated 135 million people will die before 2020 because they lack safe drinking water and proper sanitation. First and foremost, access to clean water means saving these lives. But it also means sub-Saharan Africa no longer loses the 5 percent of its gross domestic product (GDP) that's currently wasted on the health spending, productivity losses and labor diversions all associated with dirty water. Furthermore, because dehydration also lowers one's ability to absorb nutrients, providing clean water helps those suffering from hunger and malnutrition. As a bonus, an entire litany of diseases and disease vectors gets wiped off the planet, as do a number of environmental concerns (fewer trees will be chopped down to boil water; fewer fossil fuels will be burned to purify water).
