    Hydraulic fracturing, or fracking, provides critical energy for society, but also uses large amounts of fresh water while producing corresponding amounts of wastewater. Water-based foams, which use about 90 percent less water than fracking fluids, provide an alternative, but the mechanism for foam-driven fracture in such drilling is not well understood.

    U.S. Department of Energy Secretary Rick Perry toured the Princeton Plasma Physics Laboratory (PPPL) Thursday, Aug. 9, saying that national labs like PPPL have the potential to change the world through their scientific research. 

    “Fusion is incredibly important not just to this institution, not just to the Department of Energy, but to the world we live in,” Perry said during a meeting with PPPL staff. “If we are able to deliver fusion energy to the world, we can change the world forever.”

  • Princeton astrophysicist Bhattacharjee leads team to create framework for an optimal fusion energy device

    Stellarators, fusion facilities with a “twisty” design, have long played second fiddle to doughnut-shaped tokamaks that better confine the plasma that fuels fusion reactions. Now, in a development with major implications for the effort to replicate on Earth the fusion reactions that power the sun and stars to produce a virtually limitless supply of electricity, an international collaboration led by Princeton University has won a major private grant to create the framework for an optimum stellarator that combines the best features of both types of fusion reactors.
