Offshore wind farms could help capture carbon from air and store it long-term – using energy that would otherwise go to waste

Wind turbines often can produce more power than is needed for electricity onshore. That extra energy could be put to work capturing and storing carbon.

What is the best mask for COVID-19? A mechanical engineer explains the science after 2 years of testing masks in his lab

The CDC’s updated mask guidelines say that cloth masks offer the least protection from COVID-19. Differences in the materials masks are made from and the ways they fit are the reason.

Could 5G really ground planes? Why the US has delayed rolling out the mobile internet technology around airports

The radio frequency at which 5G operates in the US is close to that of an important piece of aircraft equipment, called radio altimeters.

We created the first AI-powered solar electricity backup system for houses in sub-Saharan Africa

Sub-Saharan Africa is one of the world’s most sunlit regions. A prototype generator uses that sunlight in place of diesel to support unreliable electricity grids.

How 5G puts airplanes at risk – an electrical engineer explains

Airplanes use radio waves to determine how far off the ground they are. New 5G cellphone services come close to the same frequencies the airplanes use. Here’s how that can be a problem.
