4. Storage batteries (Li ion, solid polymer electrolyte) that have small volumes and masses and high energy storage densities are in demand for both electric and hybrid vehicle applications. Estimate the smallest weight battery that could be used to provide full vehicle power for one hour of urban commuting in a family-sized five-passenger sedan. And, do some research to determine if the range (energy and mass) you calculated is realistic. Explain why or why not in 2-3 sentences. You can assume: The minimum power levels for such vehicles are 20 hp at average speeds, and the maximum power levels are 40 hp at peak acceleration. One hour of driving = 40 hp for 15 minutes + 20 hp for 45 minutes Li ion solid polymer electrolyte batteries have a specific energy density of 1400 kJ/kg

2. Some of the first power-generating wind turbines were small, having blades with a radius of 8.00 meters. Currently, the largest wind turbine has a radius of 164 meters. Because the small wind turbines are closer to the ground, they often experience smaller wind speeds. Given the information below, how many small wind turbines would be needed to produce the same power output as one large wind turbine? For both wind turbines, assume the air density is 1.23 kg m³. Small Wind Turbine Large Wind Turbine Wind turbine blade radius 8.00 m 164 m Wind turbine efficiency 35% 45% Wind speed 3.50 m s1 5.50 m s1

If we wanted to supply all the electricity needs for New York City (NYC), with a popula- tion of about 10 million people, using photovoltaics technology, how much land area would we need? What other elements would be required for such an idea to work for NYC? How large of an investment would this involve, and how would the price of electricity in ¢ per kWeh have to increase in order to recover that investment in 10 years at an interest rate of 8%? For comparison, the average New Yorker paid 12¢/kWeh in 2002.
