Can mirrors and ceramic sand solve our energy problem?

How can a giant field of solar mirrors create enough energy to power over 200,000 homes? Physics Girl Dianna Cowern tours the Mojave Solar Project, a concentrated solar power (CSP) plant in the desert of San Bernardino County, California, to find out. Watch How Mirrors Could Solve our Energy Problem, one in a series of sponsored videos about renewable energy. Cowern explains:

“The ultimate goal of concentrated solar power is to drive a turbine. The sun hits mirrors that then reflect to a special material and heat it up, and that material boils water, and then the steam drives the turbine that creates electricity.”

Cowern reviews a few versions of this technology and also talks with Dr. Cliff Ho of Sandia National Labs in Livermore, California. Via video chat, he shares how sand-like ceramic particles can absorb and store heat from the concentrated sunlight, an innovative upgrade for energy storage.

How? That heat created from sunlight can still generate energy, even after the sun has set, because the ceramic sand takes around ten hours to cool down.

“We believe particles are the best option for going to higher temperatures for advanced power cycles. The particles are inexpensive, durable and non-corrosive. They can be stored directly, they don’t freeze and they can reach temperatures over 1,000 C.”
