A meeting of the minds when NYC °CoolRoofs visits PPPL The cool roof at PPPL was downright chilly when two representatives from New York City Mayor Michael Bloomberg’s NYC °CoolRoofs program came to visit the Laboratory recently. But the meeting itself was warm and could lead to a partnership between the city group, PPPL and Princeton.

PPPL-designed coil critical to experiment arrives in stellar condition Engineers at the U.S. Department of Energy’s Princeton Plasma Physics Laboratory (PPPL) have designed and delivered a crucial barn-door size component for a major device for developing fusion power. The component, called a “trim coil,” marks the initial installment of one of the largest hardware collaborations that PPPL has conducted with an international partner.
