Giant nanomechanical energy storage capacity in twisted single-walled carbon nanotube ropes - Nature Nanotechnology
www.nature.com
A single-walled carbon nanotube spring stores three times more mechanical energy than a lithium-ion battery, while offering wide temperature stability and posing no explosion risk.

    Sure, if you only count the very light nano wire toward your energy density and not the giant mechanism to make it useful.

      For now, assuming it pans out.

      Remember that ~60 years ago, computers less powerful than the microcontrollers in your “dumb” appliances filled entire rooms.
