He said it would take $8 billion to build a solar power plant for the enormous energy needs of antimatter production and cost $670 million per year to operate. The idea is just that, for now.

A compact method of detecting neutrinos provides new tests of physics theories and could lead to new reactor-monitoring methods.

These antimatter particles are produced in abundance ... they carry vital information about the reactor's operations, including power output and isotopic composition. What sets antineutrinos ...
