Both!

The National Ignition Facility (NIF) is a large research device located at Lawrence Livermore National Laboratory. The NIF uses powerful lasers to heat and compress hydrogen fuel to the point where nuclear fusion reactions take place. It is currently the largest and most energetic inertial confinement fusion device in the world. Researchers use the NIF to ensure the safety of nuclear weapons, explore the potential of fusion as a safe energy source, and understand how the universe was created.
 
In this photo, NIF Team members Bruno Van Wonterghem (left), Jim Nally (pointing) and Rod Saunders watch through a newly installed viewing window, which allows the NIF team and visitors to see inside the chamber while it is vacuum-sealed for experiments.
 
Fun fact: NIF was also used as the set for the starship Enterprise’s warp core in the movie Star Trek Into Darkness. <a href="https://lasers.llnl.gov/" target="_blank">Learn more about the NIF</a>. | Photo courtesy of Jacqueline McBride, LLNL.

Fuel cells, which work like batteries but don’t run down or need recharging, are ideal for powering material handling equipment, like forklifts and airport baggage carts, because they reduce recharging time and cut carbon pollution. This is helping them become more mainstream in the U.S., with more than 4,000 vehicles in operation in 2012, and this year, they might even be helping bring you holidays to you. | Photo courtesy of Plug Power, Inc.

Scientists at Pacific Northwest National Laboratory study the microbial interactions in the plant root systems, the rhizosphere. The rhizosphere represents a critical zone where plant roots, microbes and minerals interface, and where biogeochemical weathering provides nutrients to plants. This research program will broaden our understanding of the biogeochemistry of plant-microbe-soil interactions. Shown are the spores of an opportunistic soil fungus Penicillium sp. that associates with the plant roots, microbial biofilms and soil minerals. | Photo courtesy of Pacific Northwest National Laboratory.
