Harvesting waste thermal energy using a carbon-nanotube-based thermo-electrochemical cell.
TLDR
Thermocells are demonstrated, in practical configurations, that harvest low-grade thermal energy using relatively inexpensive carbon multiwalled nanotube (MWNT) electrodes that provide high electrochemically accessible surface areas and fast redox-mediated electron transfer, which significantly enhances thermocell current generation capacity and overall efficiency.

Torsional Carbon Nanotube Artificial Muscles
TLDR
It is shown that an electrolyte-filled twist-spun carbon nanotube yarn, much thinner than a human hair, functions as a torsional artificial muscle in a simple three-electrode electrochemical system, providing a reversible 15,000° rotation and 590 revolutions per minute.
