The whole group came up with five solutions then each person chose one. I am in the water pump group. Hurracaines are caused by if the water on the surface of the ocean is 25.6 degrees or hotter. What our wave-powered pump does is it lifts the cold water onto the surface whenever a wave goes by. We did some research and someone already had an idea to solve this problem and we are comparing our idea with his idea to see which one works better.
