1 ME 417 Design of Alternative Energy Systems Ocean Energy Problem 1. It is proposed to build an OTEC system on Lake Superior where the summer time surface temperature is 64 ° F and the deep water temperature is 6 ° C. Determine the minimum amount of surface water that must be used if this system is produce 800 kW for an allowable water temperature change of 5 ° C. 2. A current energy power system is proposed for a location where the average current speed is 0.75 m/s. Two marine turbines of 1.5 MW power are being considered for the system, which have the following conditions Turbine Efficiency Rotor Diameter Capital Cost Rhino 35% 45 m $15M Bruin 31% 52 m $12.5M Determine the energy cost ($/kWh) for each turbine and make an
