Times of India reports:

“A Utah-based company has found a new way to store solar energy – in a small ceramic disk which can store more power for less. Researchers at Ceramatec have created the disk, which can hold up to 20-kilowatt hours, enough to power an entire house for a large portion of the day. The new battery runs on sodium-sulfur — a composition that typically operates at greater than 600°F. “Sodium-sulfur is more energetic than lead-acid, so if you can somehow get it to a lower temperature, it would be valuable for residential use”, Ralph Brodd, an independent energy conversion consultant, says. Ceramatec’s new battery runs at less than 200°F. ” See full article >>
