Electrons flowing through the channel run a gantlet of silicon wires, poking through the canyon wall at strategic locations. Each time the laser pulses – which it does 100,000 times a second – a burst of photons hits a bunch of electrons, accelerating them forward. All of this occurs in less than a hair’s width, on the surface of a vacuum-sealed silicon chip.” Now if it could scale for deuterium and tritium nucleus, that would be fun. Bob Wilson
