Today, they get most of it from fossil fuels, and finding an efficient green alternative is a major challenge. Antora Energy may have a solution. Its technology, known as a thermal battery, involves using electricity to heat up graphite blocks to more than 3,200°F inside an insulated container. When a window in the container is opened, heat is released, which can also be converted to electricity with thermophotovoltaic cells. The company raised more than $50 million in venture capital in February, and it more recently started operating a commercial scale pilot project in Fresno, Calif.
