You Wish to Devise a Way to Use Wave Power $\degree$

You wish to devise a way to use wave power to heat water.You determine that approximately 108 kJ of energy are available per second from 3.05-m waves coming in along the coastline.How long would you have to collect energy from the wave in order to heat 18 kg of water from 20.0 $\degree$ C to 100.0 $\degree$ C? Assume you can transfer the stored wave energy completely to the water with no energy loss.[c_p(water) = 4.18 J/(g . $\degree$ C)]
