This MINI concept takes sustainable car manufacturing to a whole new level

As circularity slowly expands across industries, car companies are beginning to explore sustainable design as the new standard. Emblematic of that is the MINI Strip — a one-off car that resulted from a collaboration between two British brands, fashion designer Paul Smith and automotive marque Read More...

Students conceptualize pedestrian-friendly addition to local bridge

This is the case for a long bridge in Rhode Island that connects the towns of Jamestown Read More...

Automated aircraft towing tech aims to save fuel and cut emissions

Airlines consume billions of gallons of jet fuel every year to transport passengers around the world. About five percent of that fuel is used on the ground, as airliners have to run their jet engines to taxi along the runway, generating a lot of carbon emissions in the process.

The world’s first all-electric tugboat to put to sea in 2023

According to the International Maritime Organization (IMO), maritime transport emits around 940 million tonnes of CO2 annually and is responsible for about 2.5 percent of global greenhouse gas (GHG) emissions. As engineers are working to green up cargo ships with the help of low-carbon fuels, Read More...

Why public transportation systems are the perfect microgrid candidates

Fleet vehicles, including public transportation vehicles, are critical for embracing a transition to fossil fuel-free transportation, but committing to transitioning a whole city bus or train system to electric power is no easy feat. Fortunately, microgrids could play a critical role in this Read More...
