The presentation by Shadab Shaikh discusses new technologies in power generation, emphasizing the need to move away from traditional methods. It introduces various advancements, including spherical sun power generators and 3D printed solar energy trees, and explains the principle and efficiency of ocean thermal energy conversion (OTEC). The document highlights the relatively low efficiencies of OTEC compared to conventional power sources.

11. What is the efficiency?What is the efficiency?
• Maximum efficiency is limited by the Carnot efficiency.Maximum efficiency is limited by the Carnot efficiency.
– Carnot Efficiency of OTEC = 100 * ( 1 – Tc/Th )Carnot Efficiency of OTEC = 100 * ( 1 – Tc/Th )
• If surface temperature were at 24 degrees Celsius (297 K)andIf surface temperature were at 24 degrees Celsius (297 K)and
water at 4 degrees Celsius (277 K) were used?water at 4 degrees Celsius (277 K) were used?
– = 6.73% efficiency= 6.73% efficiency
• If surface temperature were at 34 degrees Celsius (307 K) andIf surface temperature were at 34 degrees Celsius (307 K) and
water at 4 degrees Celsius (277 K) were used?water at 4 degrees Celsius (277 K) were used?
– = 9.77% efficiency= 9.77% efficiency
