While agriculture and natural resources have been the main exports for Sub-Saharan Africa, investment in high tech and digital technologies is beginning to build. Across the continent, bets on high-tech manufacturing are being made. It remains to be seen if they will pay off.

Lithium-ion batteries are reliable and getting progressively cheaper, but generally deliver full power capacity for no more than four hours. But for renewable energy to fully replace fossil fuels, energy storage systems must advance to provide long and longer-term storage capability, and then deliver it on demand. There are a variety of technologies being developed for long-term storage, generally recognized as six to 12 hours.

Instead of waiting to fight diseases inside the human body, engineering can establish lines of defense further out by either intercepting and neutralizing the pathogens before they reach humans or diluting them so much that they can’t build up an infective load. Good engineering can create robust public health.

The eight digester towers at New York City's Newtown Creek Wastewater Treatment Plant seamlessly convert sewage into biogas and a dirt-like output, similar to how Mother Nature would do it. At 145 feet high and 80 feet in diameter, each egg holds about 3 million gallons of sludge, converting it into 2 million cubic feet of gas every day.

Demand for engineers across all disciplines, especially mechanical engineering, is very high as U.S. industries look to ramp up what they hope is a post-pandemic economy. They also may enjoy more relaxed working conditions as employers adapt to over a year of remote operations. They might not have to go to the office or the jobsite, at least exclusively, because many employers are continuing remote work.

Relatively few Native Americans become engineers. The barriers to increasing those numbers are issues such as poverty, poor schools, and a lack of role models. In this article, Native American engineers talk about their experiences and how their work stretches across generations.

The degree to which technical skills are needed for new graduates and early career engineers is hotly debated. By some standards, deep knowledge of digital engineering technologies has never been more important or so hard to come by. But the difference-makers, employers say, are abilities that might be thought of as “soft skills,” such as flexibility, leadership, innate curiosity, and a flair for innovation.
