Diamond bullet fired at 1000 Km/S could produce nuclear fusion, Chinese researchers say

A millimeter-sized diamond bullet fired from a linear accelerator could produce nuclear fusion when it collides with a chunk of solid methane, according to a study by Chinese researchers.

Despite the large amount of energy required to accelerate a diamond to 1,000 km/s — about 620 miles per second — the collision produces a net energy gain, according to the team’s simulations.
