Byline: Robin M. Grugal
Albany, N.Y., has become the testing ground for what someday might be the solution to our nation's troubled power grid.
Soon, 24,000 homes and businesses in the city will get power that travels underground via cables made of superconductive materials.
These materials, when cooled to minus 322 degrees Fahrenheit -- about the temperature of liquid nitrogen -- conduct electricity without resistance. That means three to five times more power can be pumped through the same conduit than with today's copper wire.
The company behind the $20 million project is Intermagnetics General Corp., which makes magnets for magnetic resonance imaging equipment used in medical diagnostics.
Sound like an odd mix of specialties? Not exactly.
Superconductivity is what gives MRI magnets their intense power. That's the connection. It makes for a nice leverage play for Intermagnetics -- a chance to build on existing expertise.
