Bruce Anderson, CEO of 247 Solar, details his company's concentrated solar technology that delivers round-the-clock clean electricity without combustion or emissions. The system uses heliostats to heat air to 1,800°F, stores that thermal energy in ceramic pellets, and converts it to electricity via a modified turbine. Paired with solar PV during daylight hours, the solution addresses intermittency at a commercial scale, with the first deployment underway in India.   Topics Covered 247 Solar www.247solar.com 24 Hours Solar Energy 1,800°F / 1000°C Air Solar Thermal Air Pressure Compressed Air ESS = Energy Storage System Natural Gas Fossil Fuel Molten Sault   Reach out to Bruce Anderson here: LinkedIn: www.linkedin.com/in/bruceanderson Website: www.247solar.com   Learn more at www.solarSEAN.com and be sure to get NABCEP certified by taking Sean’s classes at www.heatspring.com/sean solarsean.com/esipexam
