Pumps are used to get drinking water to our houses every day! And in disaster situations, pumps are essential to keep flood water out. In this hands-on activity, student groups design, build, test and improve devices to pump water as if they were engineers helping a rural village meet their drinking water supply. Students keep track of their materials costs, and calculate power and cost efficiencies of the prototype pumps. They also learn about different types of pumps, how they work and useful applications.

We hear a lot about technologies that produce carbon-free energy, but what about actually using less energy to begin with? In this episode of TILclimate (Today I Learned Climate), Harvey Michaels, lecturer at the MIT Sloan School of Management, joins host Laur Hesse Fisher to explore the three ways that energy efficiency can help us reduce carbon emissions.

This unit looks at the challenges of adapting work processes to new technology, and the resulting impact on quality, efficiency, and safety. This unit also examines the phenomena of social and technical resistance to change, especially among clinicians.

Students learn about the daily and annual cycles of solar angles used in power calculations to maximize photovoltaic power generation. They gain an overview of solar tracking systems that improve PV panel efficiency by following the sun through the sky.

Students explore energy efficiency, focusing on renewable energy, by designing and building flat-plate solar water heaters. They apply their understanding of the three forms of heat transfer (conduction, convection and radiation), as well as how they relate to energy efficiency. They calculate the efficiency of the solar water heaters during initial and final tests and compare the efficiencies to those of models currently sold on the market (requiring some additional investigation by students). After comparing efficiencies, students explain how they would further improve their devices. Students learn about the trade-offs between efficiency and cost by calculating the total cost of their devices and evaluating cost per percent efficiency and per degree change of the water.

The culminating energy project is introduced and the technical problem solving process is applied to get students started on the project. By the end of the class, students should have a good perspective on what they have already learned and what they still need to learn to complete the project.

This course focuses on some of the important current issues in strategic management. It will concentrate on modern analytical approaches and on enduring successful strategic practices. It is consciously designed with a technological and global outlook since this orientation in many ways highlights the significant emerging trends in strategic management. The course is intended to provide the students with a pragmatic approach that will guide the formulation and implementation of corporate, business, and functional strategies.

This course is intended to be an extension of course 15.902 Strategic Management I, with the purpose of allowing the students to experience an in-depth application of the concepts and frameworks of strategic management. Throughout the course, Prof. Arnoldo Hax will discuss the appropriate methodologies, concepts, and tools pertinent to strategic analyses and will illustrate their use by discussing many applications in real-life settings, drawn from his own personal experiences.

After reading a story about a supermarket, students examine the change in supermarket jobs due to the advances in technology. Students observe two demonstrations. One simulates the checkout process at a grocery store using a cash register, and the other uses scanners that are in stores today. Students conclude which method is faster and more accurate and why.

Using a household fan, cardboard box and paper towels, student teams design and build their own evaporative cooler prototype devices. They learn about the process that cools water during the evaporation of water. They make calculations to determine a room's cooling load, and thus determine the swamp cooler size. This activity adds to students' understanding of the behind-the-scenes mechanical devices that condition and move air within homes and buildings for human health and comfort.

This article describes energy efficiency as it relates to home and school energy use and provides ways that children can help.

Students explore how the efficiency of a solar photovoltaic (PV) panel is affected by the ambient temperature. They learn how engineers predict the power output of a PV panel at different temperatures and examine some real-world engineering applications used to control the temperature of PV panels.

This OER provides a substantial set of readings on transportation law and policy, suitable for use in a variety of disciplines and educational settings, including law, economics, urban planning, history, engineering, sociology, and more.

Stanford University’s Understand Energy Learning Hub provides free access to Stanford course content on energy resources from fossil fuels like oil and coal to renewable resources like the wind, the sun, and efficiency; energy currencies like electricity and hydrogen; and energy services such as transportation and buildings. Explore the Hub and build your energy literacy to address climate change and sustainability issues, engage on equity and human development challenges, participate in energy industry markets and technology innovations, and make informed energy decisions.

This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"Inhalable medications for patients with asthma and COPD can be confusing for patients and prescribers alike. The sheer variety of devices alone makes choosing the right one difficult. But among the different types currently available, one that’s proven highly valuable for nearly all patients with asthma or COPD is the dry powder inhaler. In an article recently published in the journal Advances in Therapy, researchers discuss how dry powder inhalers work, what makes them stand out, and what patients and prescribers should look for in a device. The active drug in dry powder inhalers is composed of microparticles loaded onto larger carrier particles. The inhalers’ unique internal design converts patient’s inhalation into shear forces that deagglomerate the drug particles from carriers. The drug particles are transported deep into the lung, while the larger carrier particles cling to the back of the throat and are eventually swallowed. This reliance on a powdered formula is a desirable feature..."

People use energy in all aspects of their lives for cooking, lighting and entertainment. Much of this energy use takes place in buildings, such as our homes. To save money and reduce the impact on our environment, many people are reducing their energy use. One way is to hire engineers to perform home energy audits to understand the ways we use energy and identify ways we can conserve energy. In this activity, students act as energy conservation engineers and identify the ways energy is conserved or wasted. They also learn many ways to personally conserve energy everyday.

Professor Jes Søgaard, SDU, forklarer principper for Økonomiske evalueringer (ØE). Derudover gennemgås evalueringstyper, design og analyse, rapporterede mål fra ØE samt begrænsinger og faldgruber. Jes Søgaard taler om hvordan man kan udføre analyser, som så kan bruges til at tage stilling til hvordan man vælger behandlingsmetoder i forhold til økonomiske omkostninger. Et eksempel er at undersøge: "Hvad koster lungekræft i Danmark i behandlingsudgift?"
