Princeton Plasma Physics Laboratory study suggests that a Faraday screen can help achieve the extreme temperatures needed for nuclear fusion.

Nuclear fusion, the powerful reaction that powers the Sun, also has the potential to provide abundant clean energy on Earth.

This is similar to how microwaves in an oven interact with water molecules in food. These waves transfer energy to the molecules, causing them to vibrate rapidly. This vibration generates heat, which raises the temperature of the food. “We have performed computer simulations confirming a technique that prevents the production of the unhelpful waves, known as slow modes, boosting the heat put into the plasma and increasing the efficiency of the fusion reactions,” the PPPL teamFor the first time, the PPPL team ran some 2D simulations to figure out a way of reducing slow modes.
