SARGENT Artist s rendering of an HETL workspace Oxygen Researchers are also designing and synthesiz ing materials to store large amounts of hydrogen conveniently and inexpensively And there is significant work to improve devices such as fuel cells which efficiently convert hydrogen into electrical and or thermal energy Thompson whose own research focuses on microfabricated fuel cells and processing existing fuels such as gasoline and alcohols into hydrogenrich mixtures said that the University of Michigan is in an excellent position to become the world leader in all facets of hydrogen energy research The University is already a leader in hydrogenproduction and storage research I foresee that Michigan Engineering will play a major role working with other units on campus to identify and improve alterative energy sources and to develop stratagies for carbon remediation Da ve Munson Nuclear Energy WITH THE GOUNTRY s number one graduate program in nuclear engineering Michigan Engineering s Department of Nuclear Engineering and Radiological Sciences NERS will play a major role in the U M energy initiative Bill Martin NERS professor and chair said that the department is performng research in sev eral areas related to the use of nuclear energy as a safe eco nomical and sustainable source of energy including the examination of advanced reactor concepts and new materials proliferationresistant nuclear fuels wasteminimum fuel cycles complex control methods for safer and more economical opera tion of nuclear power plants and technology that will minimize the burden that longterm storage of radioactive waste has on a waste repository such as Yucca Mountain The most important factor is nuclear reactor safety Martin said It s the subject of ongoing research in NERS as well as the subject of a course NERS 462 that s offered to seniors and graduate students We plan to make valuable contributions to the energy initiative in energyrelated research and education Priority One Energy Storage MICHIGAN ENGINEERING RESEARCHERS are investigating a range of alternatives for various sources of energy Ann Marie Sastry professor of Mechanical Engineering Biomedical Engineering and Materials Science and Engineering and her team are working on a number of highly innovative technologies that will produce renewable environ mentallyfriendly energy sources They range from batteries for vehi cles and the grid to batteries for microelectronics that can be implant ed in the body Sastry said And all of them no matter what their application might be are efficient compact and lowcost In one program her team is designing carbon particles that are about onebillionth of a meter across and when stretched to create longer con nection lengths and then packed together proper ly in clusters connect electrons but use less mass and distribute charge evenly See Materials Design at the Intersection of Nanotechnology and Energy on page 17 Our overarching objective is to develop a Microbatteries can power equally small electronics such as portfolio of technologies that address energy stor cochlear implants to restore hearing to the age issues which have become critical with d f ea increased demand Sastry said These are issues that concern us as a nation so we also want to speed a widespread adoption of these technologies and to increase awareness of the environmental impact of traditional energy sources In comparison to electrical storage hydrogen is costly to store and transport with current technology so HETL Director Levi Thompson for example is developing microfuel cells for incorporation into a fuel storage system We re working hard to use our work in storage technologies to help integrate other technologies developed at the University during the energy initiative Sastry said We re each pushing the envelopes of our fields and our strength is in combining our technologies for a more agile environmentally friendly grid Solar Energy THERE ARE MORE than 81 million buildings in the United States and according to the US Department of Energy they consume more ener gy than any other economic category including transportation and industry and almost half of it goes into heating and cooling Engineers have been looking for new ways to make buildings less wasteful and kinder to the environment The reasons for using solar power are many and convincing It s totally silent the fuel is free and completely renewable there are no emissions and the technologies photovoltaic cells and passive heat ing for example are highly reliable and very lowmaintenance Steve Forrest in addition to his duties as the University s vice presi dent for research is developing organic not biologic thin films com posed of dye molecules that conduct electricity We re making a thin film of these organic molecules which we can then put on any sub 7 FALL2006 7 MICHIGAN ENGINEER Energy strate the exteriors of buildings and windows for example The film absorbs sunlight and generates electricity At the same time it cuts out 50 percent of the light that builds up excessive heat and moves people to turn on air conditioning which gobbles up energy The Dana Building a fitting home to the School of Natural Resources and Environment supplements its energy load in a num ber of ways Photovoltaic arrays on its roof convert sunlight directly into electricity The atrium skylight lets in daylight and supplies heat to much of the building while shades on the south side of the skylight help to keep the building cool This passive solar system can decrease or increase the heating and lighting effects of sunlight and in the process lower the building s electrical energy requirements Priority One Active and passive solar power supple ments the Dana Building39s energy load There are photovoltaic panels on the roof and daylight shines into many areas of the building providing heat and light Hydroelectric Energy CURRENTLY HYDROELECTRIC POWER generation is the most widely used and efficient form of renewable energy sources capable of converting 90 percent of available energy into electricity Hydroelectric dams supply 20 percent of the world s electricity and about 11 percent of US electrical generation Canada is the leader among the world s nations producing about 64 percent of its electricity from hydroelec tric sources Lack of new sites environmental restrictions and increasing costs are limiting hydroelectric development Mike Bernitsas a professor in the Department of Naval Architecture and Marine Engineering said there s plenty of hydroelec tric energy in lowpressure lowspeed flows in rivers and oceans which we can t harness with conventional technology such as turbines or watermills Bernitsas became fascinated by Vortex Induced Vibrations V IV Engineers have made careers out of preventing VIV from damaging structures such as bridges offshore platforms marine cables nuclear fuel rods and heat exchangers in airwater flows Bernitsas said But I saw a reason to enhance VIV Bernitsas highly unconventional thinking and subsequent research led to the creation of Vortex Induced Vibration Aquatic Clean Energy VIVACE a revolutionary technology that harnesses the normally destructive energy of VIV and has become an intriguing part of the UM energy initiative He conducted his proofofconcept experiments in the UM Low Turbulence Free Surface Channel of the Marine Hydrodynamics Lab The ener
