Jon Longtin, Ph.D., P.E. Professor, Department of Mechanical Engineering,
Stony Brook University
Insights into the Stony Brook Board of Directors
Jon Longtin, PhD has been a professor at Stony Brook University’s Department of Mechanical Engineering since 1996, with his research interests ranging from energy conservation, transfer and storage, and monitoring and diagnostics to laser materials processing and the development of sensors for harsh environments. Jon currently holds 11 issued and pending patents as well as authoring more than 130 technical publications.
Wearing his academic hat, Jon runs a thriving research enterprise. He has six active research programs in progress, with funding from federal, state, and industrial sources. His largest project currently is an ARPA-E project aimed at improving the performance of dry-cooled power plants, by condensing water vapor naturally found in the combustion flue gas, and using this water for improved cooling or other uses in the plant. The key to the project is an advanced thermosyphon concept, which provided an extremely low-thermal resistance between the flue gas and the ambient environment. The technology may also be useful for desalination, geothermal applications, and advanced building cooling concepts.
Joining CEBIP provided Jon with a unique opportunity to move beyond the confines of the classroom and explore real-world applications of emerging technologies. While he enjoys his academic role at Stony Brook, “being involved with companies that are developing technologies that they hope to market was appealing to my engineering side.”
Specifically, it’s the energy side of his expertise that has proved most relevant for two CEBIP clients in particular: ThermoLift and Brimes Energy.
“ThermoLift came to Stony Brook several years ago with an extremely innovative concept for an advanced residential heat pump. I have been working with them on some of the thermodynamics and heat transfer analyses for their device, which was a natural fit for my skillset in terms of their engineering needs,” he explained.
The Brimes Energy project involves harvesting wave energy to produce electricity, and again Jon’s mechanical engineering background came into play. “CEO and founder Ramuel Maramara, had developed several clever ideas for wave energy harvesting, and together we reviewed the advantages and disadvantages of each in terms of performance, cost and ease of manufacture.”
A Mutually Beneficial Relationship
While Jon’s knowledge and experience are valuable assets for both CEBIP and its clients, he readily acknowledges the benefits he gains through his affiliation. “CEBIP provides to me a cross-section of current technologies in which people are engaged and investing. This enables me to keep my thumb on the pulse of what’s going on as well as helping me frame my own research enterprise relating to new opportunities.”
And, as his work with ThermoLift and Brimes Energy illustrates, it connects him with companies whose technologies are closely related to his background. “It’s a good complement to my traditional academic role as a professor here,” he says. “There is a benefit to students as well. If a particular engineering principle or concept is used in an innovative way, I can mention this in the classroom to underscore the fact that these concepts are important and do find use in real-world engineering applications.”
Students gain as well: “Long Island is a high-tech region with good job prospects for our graduates. With the help of CEBIP, energy-based technology businesses will continue to grow and proliferate, providing even more employment opportunities for the students of the future.”
