Novel Solar Thermal Power Concept for California Heats Up

DIMONA, ISRAEL -- On the scorched floor of Israel's Negev Desert blooms a field of 1,640 robotic mirrors that behave like sunflowers.
Slightly larger than pingpong tables and guided by a computer, they turn imperceptibly to follow the sun and focus its rays on the pinnacle of a 200-foot tower, where a water boiler will soon start producing high-pressure steam.
This futuristic assembly is Arnold Goldman's scale model and testing ground for five larger solar fields his company plans to build in the Mojave Desert to supply up to 900 megawatts of clean energy to California in the next decade.

PODCAST & VIDEO: Engineering Around Extreme Events
Extreme events, such as super floods and hurricanes, are becoming more common, so civil engineers are trying to adapt civil infrastructure such as bridges to these unpredictable and sometimes devastating meteorological events. Engineer Ana Barros discusses how engineering can prepare us for extreme weather events, but also how changing climate and population conditions can affect the ability of infrastructure to hold up over time.
