Claim 0:
1. A thermal energy storage system comprising:
a firebrick checkerwork comprising one or more conductive firebrick layers, each conductive firebrick layer comprising a plurality of electrically conductive semiconductor-doped metal oxide firebricks having one or more vents to allow airflow through the firebrick checkerwork; and
a first electrode comprising one or more electrode firebrick layers, each electrode firebrick layer comprising a plurality of electrode firebricks, the first electrode configured to receive electrical power from a source;
wherein the firebrick checkerwork is heated due to application of the received electrical power, and wherein air flowing through the firebrick checkerwork is heated by the firebrick checkerwork.
