Phosphors are essential to fluorescent lighting, and thus office parks the world over, but their use of rare-earth elements makes them less than ideal. To address that issue, new types of phosphors have been developed that use substantially less rare-earth elements than current phosphors found in fluorescent bulbs. This could reduce the reliance on the limited supplies of rare-earth elements until fluorescent lighting can be completely replaced by LED lighting, which isn't expected to occur for over a decade.
A research team from the Department of Energy’s Oak Ridge National Laboratory (ONRL) has created a new model for how we can connect the way we power our homes and vehicles. Dubbed AMIE (Additive Manufacturing Integrated Energy), the platform features special technology that allows a bi-directional flow of energy between a dwelling and a vehicle. In other words, the house can fuel the car and the car can fuel the house. What's more, ORNL used 3D printing technology to build the dwelling and the vehicle, before successfully trialing the new energy system.
