Is It Time to Call into Question the Viability of Commercial eVTOLs?

Convenience is an important aspect of urban air mobility. If we consider safety, security, speed, and affordability as minor components of the umbrella term ‘convenience’, engineers have an arduous ahead road to make eVTOL (electric vertical take-off and landing) technology convenient...

Accurately Detecting Earthquakes: Can We Engineer a Solution?

While there has been much progress in disaster predictions in certain areas, such as hurricanes, earthquake detection is falling behind. Now, engineering teams are stepping up to the plate, hoping that they can use AI areas, such as machine learning and complex algorithms, to create the beginnings of a solution.

Exploring the Viability of Electric VTOL Aircraft for Commercial Transport

The reduction in conventional traffic congestion and greenhouse gases are just some of the advantages that eVTOL (electric vertical takeoff and landing) aircraft offer over current transport in growing cities. However, are we ready to adopt the technology as a means of commercial transport anytime soon?

The EU Has Pushed for a ‘Battery Passport’ to Support Its Green Energy Goals — But Is This Enough?

Policymakers require comprehensive, circular sustainability in devices’ battery life cycles. They must ensure that batteries are given a second (if not, a third) life. We discuss the EU’s potential answer to this, namely its Battery Passport, and ask how viable such a passport could be.

Will Micromobility Ever Become Fully Popularised in Europe’s Cities?

Micromobility is technically illegal on some of Europe’s streets, but its increasing public demand and eco-friendliness suggest that it should be pushed forward. We look at some of the many companies that are helping to bolster electric micro vehicle uptake, and ask: could it ever be considered as practical as driving a car?

How the University of Kentucky and Lexmark’s Vertical Recycling Project Shows Promise in E-Waste Management

The global dedication to a circular economy and sustainable electronics has been impaired by geopolitics and the trade wars, driving engineers and manufacturers to find new vertical solutions. Accordingly, the University of Kentucky and Lexmark have been working together to introduce novel e-waste (electronic waste) recycling methods.

Is the UK Rushing the Electric Vehicle Revolution?

In 2020, the UK government announced its plans to ban the sale of new petrol and diesel cars by 2030—an admirable, but incredibly ambitious, aim. Given the infrastructure and charging network required, the question arises: is the UK’s target viable, or is it rushing the electric vehicle revolution?

Is Vehicle-to-Grid Technology Sustainable?

We reportedly leave our cars parked up to 95% of the time, and on top of this, electrical grids currently have limited storage facilities. Points such as these have inspired a potential solution: vehicle-to-grid (V2G) technology. We consider the extent to which this promising power innovation may be sustainable.

Following the UK’s 2030 Petrol Ban Announcement: What Can the Country Do for a Better EV Infrastructure?

The large-scale production of EVs (electric vehicles) is already well underway in the UK and may well revolutionise its automotive industry, particularly after the government’s recent petrol ban announcement. Nevertheless, for the UK to accommodate its number of EVs on the road, further technological and infrastructural considerations are required.

Recycling Electronic Waste: Could Magnetic Density Separation be the Answer?

Magnetic density separation (MDS) offers many opportunities in recycling and is already used in some recycling plants for mixed plastic waste streams. Now, researchers are focusing MDS on electronic waste management, meaning it could one day be industrialised into a sustainable, mass-recycling solution for electronics.

Beyond Conventional E-Studies: Immersive Learning Opportunities for Electrical Engineers

Virtual reality and augmented reality (or VR and AR) are just two examples of human-machine interfaces (HMIs) that are integral to immersive learning. Using industry-focused simulations, such HMIs can educate both prospective and experienced electrical engineers for practical work—and ultimately help companies to safely and affordably take on engineering graduates.
