Imagine a metal that's stronger, lighter, and more energy absorbent than steel -- yet is cheaper to make. That's the dream of Christina Lomasney, CEO of Seattle-based Modumetal. The company, which Lomasney founded in 2006 with chemical engineer John Whitaker, grows its product (also called Modumetal) in a tank full of acid. Scraps of nickel, iron, and other metals are dissolved in the acid and then reborn, with a series of electric charges that alter the metals' atomic structure. More electric jolts are used to shape the metal as it grows, so it conforms to a mold placed inside the tank. Modumetal, Lomasney says, will eventually be used to create lightweight bulletproof vests, heat-resistant aircraft turbines, and vehicle suspension systems that can absorb some of the energy from a bomb blast. The company has 13 employees and an $850,000 research and development contract with the U.S. Defense Logistics Agency. By next year, Lomasney hopes to have prototypes of turbine blades and vehicle suspensions ready for testing.
