| Providing power when all conventional sources fail...
Sound far-fetched? A one-megaton nuclear bomb detonated 250 miles over Kansas, for example, could cripple many modern electronic devices and systems in the continental US and take out the power grid for a long time. "A rogue state or terrorist organization could easily acquire nuclear material for a smaller weapon for $20 million," says Charles Manto, president of Instant Access Networks LLC (IAN). "That weapon could be fitted onto a Scud missile for as little as $100,000, fired and detonated 80 miles into the air and affect the entire US east coast, causing up to $10 trillion in damage before you spend a nickel to fix anything." A solar storm similar to the one that occurred in 1859, which shorted out telegraph wires in the United States and Europe, could wreak havoc on electrical systems. Each of the above scenarios can create a powerful electromagnetic pulse that overloads electronic devices and systems. IAN staff and Frostburg State University physics and engineering professor Hilkat Soysal are teaming - through a $165,000 project recently approved by the Maryland Industrial Partnerships (MIPS) program - to create renewable energy-powered, electromagnetic pulse (EMP)-protected microgrids that could provide electricity for critical infrastructure facilities in the event of such disasters. "The MIPS award enhances our commitment to renewable energy research," says Frostburg State University President Jonathan C. Gibralter. "It builds upon the $738,000 Sustainable Energy Research Facility (SERF) award we just received from the Department of Energy and illustrates our interest in supporting workforce and economic development in western Maryland." IAN has developed a patent-pending shielding technology that encloses a room or similar structure and protects it from EMP events. IAN's shielding, which includes electrically isolated layers of steel and aluminum, is up to 70 percent lighter than materials traditionally used by the military and other sources for EMP protection. This enables EMP-safe rooms to be portable. IAN's shielded rooms can protect mission critical fiber optic network nodes and data or communication centers. They can also house generators, which, when several are connected, create a micro power grid, or microgrid, that can provide power to a campus or entire communities. "A microgrid could easily power a city, a hospital, or a campus," says Manto. "The idea is to create islands of power to reduce the cascading effects of a wide-scale failure." The challenge is finding a long-term energy source for microgrids, as it could take years to rebuild power infrastructure after a strong EMP event. That is where the MIPS project comes in. Soysal's research team will evaluate wind and solar solutions and the optimal locations for them in western Maryland and the surrounding region. "FSU physics and engineering faculty Oguz Soysal and Eric Moore will guide a group of students to evaluate the energy consumption profile of mission critical facilities and infrastructures, identify the wind and solar energy potential of possible sites, and develop an optimal design for the sustainable energy supply units and microgrid," says Hilkat Soysal. FSU senior research fellow David Blank will provide prototype computer simulations for a next-generation multi-flex fuel generator that is 40 percent more efficient than traditional engines. The FSU team and IAN staff together will investigate additional renewable energy subsystems that the company can integrate into the EMP-protected microgrid. "Long-term, renewable energy is critical for powering back-up electrical systems," says Manto. "What's more, in EMP scenarios the cost model for renewable energy changes because you have to eliminate the cheap, non-renewable fuels and the availability of the present electric grid. Renewable energy, even at a higher price, becomes cost-justified. We are effectively jump-starting alternative energy development." FSU is acquiring a residential-scale wind turbine for the project, which will be used to develop models for powering the microgrid. University researchers and IAN staff will also create designs to protect a wind turbine from an EMP attack. FSU and IAN are also planning to build the nation's first EMP-protected business continuity park. It will be located next to the FSU Renewable Energy Center at the university and include input from the Public Technology Institute (PTI). The park will give urban area businesses and government agencies a remote place to backup their data and an alternative place to work in the wake of a disaster. PTI plans to review the EMP-protected business continuity concept among local governments nationwide. Based in Frostburg, IAN was founded in 2004 through $1 million in seed money from IAN staff and private investors. The company received a $70,000 TEDCO Maryland Technology Transfer Fund grant in July, 2007 to develop prototypes of lightweight shielding systems that can be mass-produced and offer critical infrastructure protection from electromagnetic interference.
