Answer 1

$\large\mathcal\purple{HERE\:IS\:YOUR\:ANSWER}$

$\small{\boxed{\mathcal{OTEC}}}$Means Ocean Thermal Energy Conversion.

$\sf\small{The\:principal\:of\:OTEC\:bases\:it\:as\:follows\::--}$

The water at the surface of the ocean is warmer then the water at deeper depths.

This temperature Difference is used by Ocean Thermal Energy Conversion(OTEC) systems to generate electricity.

$\sf\large{Working\:of\:OTEC\::--}$

• ✧In OTEC pants, the energy of the warm water at the surface of the ocean is used to convert liquid ammonia (has a very low boiling point) into gaseous state.
• ✧The vapour of Ammonia at high pressure is used to spin the turbines of the generators which convert the thermal energy of the ocean into electrical energy.
• ✧The used ammonia ammonia vapour passes through a condenser where cold water which is found from the deepest part of the ocean, condenses the Ammonia vapour back into the liquid form.
• ✧This processes repeated again and again to get continues production of electricity.

$\sf\large{Thing\:to\:Remember\:==}$

The temperature difference between the warmer water at the surface of the ocean and the cold water at the depths upto 2 kilometres should be 293 Kelvin (20° C) or more.

Answer 2

Answer:

The full form of OTEC is Ocean Thermal Energy Conversion. It is based on the temperature gradient between upper and lower layers of the ocean
