PPPL physicist Fatima Ebrahimi has used high-resolution computer simulations to confirm the practicality of the CHI start-up technique. The simulations show that CHI could produce electric current continuously in larger, more powerful tokamaks than exist today to produce stable fusion plasmas.

Rutgers engineers have embedded high performance electrical circuits inside 3D-printed plastics, which could lead to smaller and versatile drones and better-performing small satellites, biomedical implants and smart structures. They used pulses of high-energy light to fuse tiny silver wires, resulting in circuits that conduct 10 times more electricity than the state of the art, according to a study in the journal Additive Manufacturing. By increasing conductivity 10-fold, the engineers can reduce energy use, extend the life of devices and increase their performance.
