Heat Storage for Solar Heating The purpose of this lab is to teach you about: Ø heat storage devices (necessary for implementation of solar energy) Ø Calorimetry Ø measuring Hfusion (for sodium thiosulfate pentahydrate) 1. Look carefully at Figure 1. 2. Over the past 25-30 years world energy demand has doubled. Over the next 25-30 years it is expected to double again. In this period, nuclear power has provided a relatively constant 20-25% of US electricity. What happens as we have more hybrid and plug in electric cars?

180,000 mirrors that concentrate the suns rays onto 18,240 solar receivers The solar receivers heat a transfer fluid to 735° F, which passes through a heat exchanger, changing water into steam to drive a conventional turbine connected to a generator that produces electricity Utilizes proprietary tracking technology to concentrate the sun’s rays and track the sun’s location during peak demand hours
