Topic: “Alternative fuels for transportation – drivers, options and trends”

Despite the fact that the idea of using alternative fuels for transportation applications is as old as the internal combustion engine itself, 95% of vehicles worldwide are powered with conventional fuels. In light of concerns over limited fossil resources as well as regulated and greenhouse gas emissions several alternative fuels have been promoted over the last decades with ethanol and electricity currently being the most dominant options. However, most (all) alternative fuels share similar shortcomings in terms of infrastructure, storage and vehicle range. This seminar discusses drivers for alternative fuels research, highlights past and predicted trends for non-conventional fuels and outlines some of the main challenges for various alternatives.

Mechanical Engineering – Engineering Mechanics Graduate Seminar: Thurs., Mar. 7 at 4:00 in 112 MEEM. Dr. Joshua M. Pearce from the Department of Materials Science & Engineering and the Department of Electrical & Computer Engineering here at Michigan Technological University. His presentation is entitled ‘The Rise of Open-Source 3-D Printing (Or How We Can Make Everyone a Mechanical Engineer)’.

Dr. Joshua M. Pearce received his Ph.D. in Materials Engineering from the Pennsylvania State University. He then developed the first Sustainability program in the Pennsylvania State System of Higher Education as an assistant professor of Physics at Clarion University of Pennsylvania and helped develop the Applied Sustainability graduate program while at Queen’s University, Canada. He currently is an Associate Professor cross-appointed in the Department of Materials Science & Engineering and in the Department of Electrical & Computer Engineering at the Michigan Technological University where he runs the Open Sustainability Technology Research Group. His research concentrates on the use of open source appropriate technology to find collaborative solutions to problems in sustainability and poverty reduction. His research spans areas of electronic device physics and materials engineering of solar photovoltaic cells, and 3-D printing, but also includes applied sustainability and energy policy.

Abstract: “The Rise of Open-Source 3-D Printing (Or How We Can Make Everyone a Mechanical Engineer)”

The benefits of this economy of scale have driven a historical trend towards large-scale manufacturing in low-labor cost countries (e.g. China), especially for the now ubiquitous inexpensive plastic products. However, advances in rapid prototyping with 3-D printing have challenged this cost savings paradigm. With the recent development of low-cost, open-source and self-replicating 3-D printers there is now a technically viable form of distributed manufacturing of many plastic products. The costs of the products are 10-100X less than commercial products and can be ultra-customized. In addition, using distributed open-source 3-D printing for manufacturing eliminates non-productive intellectual monopoly rents and associated encumbering overheads, almost all subtractive waste, allows for lower fill products, and cuts most embodied energy transportation, distribution and packaging-related pollution. This indicates that 3-D printing will not simply be a fad, but a fundamentally new way of providing goods to the world’s population via a transition to local (e.g. U.S. or even U.P.) manufacturing. These properties are already attractive for a large percentage of the population and in the last few years the number of 3-D printer operators has grown rapidly, essentially democratizing mechanical engineering. However, this ‘maker’ movement is primarily made up of amateur DIY engineers and thus there exists an enormous opportunity for traditional engineers to help accelerate the technical progress. This seminar will summarize the state-of-the-art of open-source 3-D printers, the Michigan Tech Open Sustainability Research Group’s work on distributed manufacturing, and conclude with an invitation to participate in what the Economist calls the “next industrial revolution”.

Abstract: Success in Engineering is More Than an Equation

Success in engineering comes from working with people. Learning how to work with other engineers and non-engineers alike is paramount to accomplishing your goals. If you want to develop leading edge technical solutions you need knowledge, experience and creative thinking. These things come from groups of engineers, designers, and marketing people. Success requires leadership to get these different people working together to accomplish great things.

Abstract: COOPERATIVE PAYLOAD TRANSPORT BY ROBOT COLLECTIVES

Cooperative material-handling by a fleet of decentralized manipulation agents has many applications ranging from hazardous waste removal, material handling on the shop floor, to robot work crews for planetary colonization. Our long-term goal is the development of a theoretical and operational framework to model, analyze, implement and validate cooperative payload transport capabilities in such distributed robot collectives.

Our particular focus is on creation, control and active reconfiguration of marching formations of wheeled mobile robots for cooperative payload transportation tasks. The selection of the underlying physical/informational infrastructure, system architecture, and mechanisms of cooperation creates many alternatives. A systematic framework is therefore critical for evaluation/selection of suitable implementations with quantifiable cooperative-performance benefits and forms the focus of our research activities. In particular, we will present our efforts to develop methodologies for design and optimization of formations for apriori known tasks, adaptation of formations for changing tasks and scalable schemes for control under the common theoretical but computationally tractable framework.

Time permitting, I will also provide a brief overview of the many other related research initiatives ranging from: (a) uneven terrain locomotion systems; (b) human-computer interfaces for mediated teleoperation; (c) haptic user-interface design and (d) quantitative surgical skill assessment.

Topic: Turbulent Jet Ignition: An efficient, clean combustion concept for the future?

In order to meet future global emissions goals, in the short to medium term it will be necessary to continue to improve the fuel consumption of the spark ignited gasoline engine. Gasoline engine downsizing is the dominant technology being implemented in the US and globally. In addition technologies such as variable valvetrains and stratified lean combustion have been implemented by some manufacturers. This presentation considers the application of a homogenous ultra lean combustion system to current and future engine technologies. The ultra lean combustion system is achieved via a high energy Turbulent Jet Ignition system. Turbulent Jet Ignition is an advanced spark initiated prechamber combustion system. The ultra lean combustion system has been shown to achieve high thermal efficiencies and low NOx emissions. Furthermore the improved knock resistance of the system allows, due to the distributed ignition sites, improvements in the compression ratio or a synergy with boosted applications.

Topic: Energy Storage for Power Grid Integration of Renewables

Renewable energy sources, solar, wind, etc, are becoming a larger proportion of overall electrical energy production. In order to improve the utilization efficiency of these new sources in the existing power grid, energy storage will be needed. Numerous energy storage modalities are examined, with commentary on advantages and disadvantages of each. Selection strategies will be discussed.
