20. A regenerative braking system stores kinetic energy of a car so that it can be recovered when the vehicle resumes moving. One way to do this is to “store” the energy in a spinning flywheel. One such design uses a solid disk flywheel with moment of inertia 0.040 kg m2 and maximum rotation rate 45000 rpm. (a) What is the maximum energy storage? (b) In principle it could store the kinetic energy of a 1700 kg car moving at what speed before braking? (c) If this energy is used to start the car moving again in 10.0 s, what is the power output of the system?
Select a conventional ICE (Internal Combustion Engine) passenger car from the market. Convert the ICE powertrain to an electric powertrain using the structural and performance parameters of the vehicle by calculating the electric motor shaft power, torque and speed, sketching the required graphs of the vehicle performance, selecting a proper gearbox ratio, analysing the gradeability performance of the car, selecting a battery pack and define battery voltage, current and energy capacity (Give thereasons of your selection), and defining the performance and energy consumption of the car for a specific drive cycle (calculate the cost of the drive considering the price of electricity too).

3. The U.S. auto industry produces approximately 6 million vehicles a year, each containing roughly 1.5 metric tons of fabricated metal. Consider a future wind-turbine industry having half of the auto industry's mass throughout of wind turbine units. Each unit has a specific weight of 75 kg/kW rated (nacelle components plus tubular tower only). a. At a wind-turbine capacity factor of 0.3, how long would it take to replicate the 2008 U.S.-installed average electric power rating of 1035 GW? b. Discuss (5-10 sentences) the relevant factors that would determine whether a wind machine industry of this size could be successfully operated sustainably over periods on the order of several centuries.
