Technology Overview. Rammed Aggregate Piers are a patented/proprietary ground improvement system that uses compacted aggregate to create stiff pier elements. The installation process modifies the soil surrounding the piers.
Foxfire, also sometimes called fairy fire, is the bioluminescence created by some species of fungi present in decaying wood. The bluish-green glow is attributed to luciferase, an oxidative enzyme, which emits light as it reacts with luciferin.
Cherenkov radiation glows because the core of the Advanced Test Reactor is submerged in water to keep it cool. In water, light travels at 75 percent the speed it would in the vacuum of outer space, but the electrons created by the reaction inside of the core travel through the water faster than the light does.
