The research aimed to describe the development of solar electric cars as a prop in energy conversion learning using the analyze, design, develop, implement, and evaluate (ADDIE) model and to ascertain the effectiveness of an electric car as a prop in energy conversion learning. Utilization of prop in the learning process is one way to support the…

The technological innovation of wind power is crucial to energy security and energy structure transformation. The Chinese government has been committed to improving the innovation of the wind power industry for decades. Although academic researchers and wind power policymakers have been widely concerned about the absolute score of innovation…

Hydrogen production from electrochemical water splitting via hydrogen evolution reaction (HER) powered by sustainable energy has been recognized as one of the most promising alternatives to traditional fossil fuels. To integrate the fundamental knowledge of chemistry, electrochemistry, and materials science with practical application and…

A magnetic stirrer is an indispensable instrument in any laboratory setting. Commercially available stirrers are costly and have a defined life-span. The construction of a low-cost magnetic stirrer based on pulse width modulation is described. The design reported uses mainly recycled parts which results in a robust and efficient device at a very…

Metal-air battery technology is a promising new energy storage solution in the green energy economy but also an excellent tool to educate students on the working principles of batteries. A simple yet powerful construction of a metal-air battery is shown, which consists of a plastic mint box, a cathode, an anode, and an electrolyte. Furthermore,…

What if "every breath you take, every move you make" (Sting 1983) could be harnessed to produce renewable energy? Triboelectric nanogenerators (TENGs) are state-of-the-art devices researchers are studying to do just that--convert kinetic energy into electrical energy at the source (Saurabh Rathore 2018). This type of electrical energy is…

Contribution: This article proposes a comprehensive graduate course on magnetic design that addresses existing gaps in current power electronics (PEs) education, provides theoretical foundations and hands-on skills, and matches syllabi coverage with current societal needs for electronic energy conversion. Background: A growing worldwide interest…

In this article, we discuss the tensions surrounding science, biopower, and citizenship that have been thrown into sharp relief by the COVID 19 pandemic. We situate these tensions in the epistemological and political conflict between science, public health education, and alternative medical systems that has been rekindled by the pandemic in India.…

The "electric grid" is the system of power generators, power lines, and other equipment that transports electricity from where it is generated to where it is used. Electricity and its distribution are crucial to the functioning of modern society, yet its dynamics often go unseen and unnoticed by the public. Teaching about the sources…

The application of the metaverse provides a new perspective for educational innovation and talent training in the new century. By creating multi-channel perceptions such as sight, hearing, and touch through the VR/AR/MR immersive environment, the study found that learners' emotional engagement and cognitive level can be effectively improved in the…

Contribution: A novel multidisciplinary undergraduate course on alternative energy (AE) engineering that addresses gaps in current AE education, provides hands on skills, and matches topical coverage with societal needs. Background: Resource depletion and emissions associated with burning fossil fuels have led to growing worldwide interest in…

After the mushrooming growth of the institutions providing technical education in India, questions are being raised about the quality of education dispensed to technical graduates. The purpose of this study is to recognise the various factors, in order of their importance, that are responsible for declining quality of technical education in…

Powerbanks differ in the amount of energy they can store. Usually this capacity (in a colloquial sense) of the powerbanks is stated in the form of charge in mAh for effective advertising. From a physical point of view, shouldn't the energy that a powerbank can provide be of interest? For students, charging smartphones with power banks is…

Introduction: This paper presents a didactic model that was developed at Assiut Integrated Technical Education Cluster (ITEC) to support the implementation of a competency-based training system (CBT). ITEC was established in Assiut, Egypt, to meet community demands, to raise the status of vocational education, and also to change the community…

Using data on a mid-sized community college in northeast Ohio as a case study, we examine patterns of enrollment in petroleum technology credential programs and labor market returns to those credentials. The enrollment analysis yields mixed results. Strong industry conditions represented by an increase in oil prices is associated with a decline in…
