New Airborne Observing Systems for Climate Research: Challenges for Laser, Electronics, and Optical Designs
James G. Anderson, Harvard Univ., USA

A brief review of dominant feedbacks within the climate structure that set the timescale for irreversible changes to the Earth’s climate system is presented. Emerging developments defining a new era of airborne observing systems are linked to strategies addressing key unanswered scientific questions regarding the climate system. Given these new observing systems, it is demonstrated that the new developments constitute key challenges for new designs in lasers, electronics and optical systems.

Thirst for Power: Energy, Water and Human Survival
Michael E. Webber, The University of Texas at Austin, USA

Abstract: This talk offers a big picture perspective that reveals the interdependence of the world’s two most critical resources -- energy and water. In addition to identifying the seriousness of the challenges, it lays out an optimistic approach with an array of solutions.

As Deputy Director of the Energy Institute, Co-Director of the Clean Energy Incubator, Josey Centennial Professor in Energy Resources, Author, and Professor of Mechanical Engineering, Michael E. Webber trains the next generation of energy leaders at the University of Texas at Austin and beyond through research and education at the convergence of engineering, policy, and commercialization.

His recent book, “Thirst for Power: Energy, Water and Human Survival”, which addresses the connection between earth’s most valuable resources and offers a hopeful approach toward a sustainable future, is receiving wide praise. His television special Energy at the Movies was in national syndication on PBS stations 2013-2015, and a suite of energy literacy tools titled Energy 101, including videos, online courses, and an interactive ebook, is available globally.
 He was selected as a Fellow of ASME, has authored more than 300 publications, holds 4 patents, and serves on the advisory board for Scientific American.  Webber holds a B.S. and B.A. from UT Austin, and M.S. and Ph.D. in mechanical engineering from Stanford.  He was honored as an American Fellow of the German Marshall Fund, an AT&T Industrial Ecology Fellow, and on four separate occasions by the University of Texas for exceptional teaching.

Keynote Speakers

North American pollution measurements from geostationary orbit with Tropospheric Emissions: Monitoring of Pollution (TEMPO)
Kelly Chance, Harvard-Smithsonian Center for Astrophysics, USA

Abstract: TEMPO, the first NASA Earth Venture Instrument, launches soon to measure atmospheric pollution from Mexico City and Cuba to the Canadian oil sands, and from the Atlantic to the Pacific. It does this hourly at high spatial resolution to measure the key elements of air pollution chemistry. Geostationary measurements capture the variability in the diurnal cycle of emissions and chemistry at sub-urban scale to improve emission inventories, monitor population exposure, and enable emission-control strategies.

Kelly Chance is a Senior Physicist at the Smithsonian Astrophysical Observatory and the Principal Investigator for the NASA/Smithsonian Tropospheric Emissions: Monitoring of Pollution (TEMPO) satellite instrument that is currently being built to measure North American air pollution, including Mexico, the U.S., Canada, Cuba and The Bahamas at high spatial resolution, hourly from geostationary orbit (tempo.si.edu). He has been measuring Earth’s atmosphere from balloons, aircraft, the ground and, especially, from satellites since receiving his PhD from Harvard in 1977. Measurements include the physics and chemistry of the stratospheric ozone layer, climate-altering greenhouse gases, and atmospheric pollution. Together with Prof. Randall V. Martin, Dr. Chance has just published “Spectroscopy and Radiative Transfer of Planetary Atmospheres,” based upon their teaching, by the Oxford University Press.

Innovation in optical materials design to manufacture for driving high performance photovoltaics cost-effectively
Kwang-Leong Choy, University College London, UK

Abstract: This presentation gives an overview of the innovation in the design of optical nanostructures and advanced thin films. These include transparent conducting electrodes, anti-reflective coatings, window layers and absorbers. Such materials development combining with the innovation in non-vacuum, eco-friendly and low temperature manufacturing processes have contributed towards the development of high performance thin film solar cells cost-effectively.

Kwang Leong Choy was a Violette and Samuel Glasstone Research Fellow at Oxford where she has developed flame assisted vapour deposition (a variant of CVD) of films, before joining Imperial College in 1994 as a Governor's Lecturer. In 2001, she was promoted to Reader for her pioneering research on the innovative non-vacuum Electrostatic Spray Assisted Vapour Deposition (ESAVD) method at Imperial College London. She has been the recipient of the Grunfeld Medal and Prize from Institute of Materials (UK) for the recognition of her contribution to innovative coating materials/processes and later she has founded a spin-out company known as IMPT Ltd to exploit the ESAVD technology. She has been the international expert reviewer for Ontario Research Fund, Hong Kong Productivity Council and Greek Ministry of Education/European Commission. She has been awarded Guest Professorships at the University of Uppsala (2001/03), Ningbo Institute of Materials Technology and Engineering (NIMTE, 2010/2012), and Chinese Academy of Sciences (CAS) Visiting Professorship for Senior International Scientist (2011/2013). 

Overview of Central Receiver Systems for Concentrating Solar Power:
Optical Advancements and Needs

Clifford Ho, Sandia National Laboratories, USA

Abstract: This presentation provides an overview of concentrating solar power (CSP) and associated optical research and needs.  CSP uses large arrays of mirrors to focus sunlight onto a receiver to heat water/steam, molten salt, air, or other media for electricity production and thermal energy storage.

Dr. Cliff Ho is a Distinguished Member of the Technical Staff at Sandia National Laboratories, where he has worked since 1993 on problems involving solar energy, water safety and sustainability, heat- and mass-transfer processes in porous media, and microchemical sensor systems for environmental monitoring.  Dr. Ho has authored over 200 scientific papers, including 10 patents, and he is an author and co-editor of two books. He received an Outstanding Professor Award at the University of New Mexico in 1997, and he received the national Asian American Engineer of the Year Award in 2010.   Dr. Ho received R&D 100 Awards in 2013 and 2016 for innovations in solar energy, and he won Discover Magazine’s The Future of Energy in Two-Minutes-or-Less video contest.  Dr. Ho received his B.S. in Mechanical Engineering from the University of Wisconsin–Madison in 1989, and his M.S. and Ph.D. degrees in Mechanical Engineering from the University of California at Berkeley in 1990 and 1993.

The New World of Lighting: SSL and Beyond
Jeff Tsao, Sandia National LaboratoriesUSA

Abstract: We review the tremendous progress that has been made in solid-state lighting for illumination, and the potential for future progress towards a new world of lighting that goes well beyond solid-state lighting for illumination.

Jeff Tsao is a Distinguished Member of Technical Staff at Sandia National Laboratories. From 1981 to 1991, at MIT-Lincoln Laboratory and Sandia, he studied laser microchemistry and the materials science of strained heterostructures, culminating in a research monograph “Materials Fundamentals of Molecular Beam Epitaxy.” From 1991 to 2001, he was research manager at Sandia then VP of R&D at E2O Communications, a U.S.-based pre-IPO fiber communications company. From 2001 to 2009, he returned to Sandia, spearheading white papers and reports which helped set larger national and global research directions, including in solid-state lighting. From 2009 to 2014, he served as Chief Scientist of Sandia’s Energy Frontier Research Center for Solid-State-Lighting Science. In 2016, he began a part-time Harvard Belfer Center Fellow appointment to begin framing and articulating guiding principles for the practice and nurturing of research.
