A Human-Powered Drill for Clean Water

Seven engineering students designed a water drill that might improve the lives of millions.

Lack of sanitary drinking water is a serious and well-known problem that continues to plague many third-world nations. In Tanzania alone, over 800,000 people do not have access to clean water.

A group of seven engineering students from Brigham Young University hope to alleviate this problem by giving Tanzanians an efficient and inexpensive way to obtain drinking water. For their senior capstone project, they have designed a human-powered drill that can dig a freshwater well much faster than many more expensive devices.

Is your lunch fresh enough to eat? Now the plastic wrap can tell you

Consumers often throw away perfectly edible food because they think it has “gone bad.” As a result, the Environmental Protection Agency estimates that food scraps constitute 12 percent of municipal landfills, making food the single largest component of the country’s waste stream.

To help prevent consumers from prematurely throwing away food, researchers are developing a plastic wrap that will change colors when the food is no longer safe to eat.

Artificial Cloud to Hover over 2022 World Cup in Qatar

Qatar, a small Middle Eastern country that has been designated host of the 2022 World Cup, is not known for its mild summers. In fact, temperatures in July regularly average over 115 degrees F (50 degrees C), which presents a serious challenge to the event’s organizers.

But not to fear – engineers from Qatar University’s Department of Mechanical and Industrial Engineering have a clever solution. Over the next ten years they plan to develop an artificial cloud that will hover over the soccer stadium and provide crucial shade to players and audience members.
