Building them with artificial muscles that run on hydrogen, instead of noisy compressed-air pumps or electric motors, could be the answer. Kwang Kim, a materials engineer at the University of Nevada in Reno, came up with the idea after realising that hydrogen can be supplied silently by metal hydride compounds. Metal hydrides can undergo a process called reversible chemisorption,
