This morning started with a lot of brainstorming. We drew a lot of diagrams and had to think about the how heavy the hot and cold water is. The warm water on top is light and the cold water on the bottom is heavy so in science terms it would be hard to push the heavy cold water down to circulate and mix together. Another thing that came up is “do we have to have a pump?” The goal of our project is to get rid of the hot spot, we might not have to pump, we could bring cold water and transport it to the hot spots but pressure (this would replace the pumping).
Just before lunch, we were talking with Giancarlo and we decided that we would go find different types of bottles that would be different shapes at the top. This would affect how the water came up when bobbing up and down in the ocean. We started by testing a PBC pipe and a funnel. We found 3 different types of bottles: Dole juice bottle (1); 2 liter soda bottle(2); and a Polar Orange Dry bottle (3). We also had a Polar sparking water bottle from yesterdays prototype (4). When we cut the ends up and tested these different bottles in water we came to the conclusion Polar bottle (3) and the juice bottle (1) were the best. The Polar bottle (3) worked the best because it was thin and narrow, the juice bottle worked the best because there is a gradual incline to the top there is also a good portion of the top that is really narrow. In addition we added a piece of plastic on the top of the water bottle (4), this piece of plastic would guide the water to go to one side or another. By the end of the day we decided to focus on the water bottle (4) and the juice bottle (1)
Max found this video when researching, it is mostly about how Bill Gates wants to helps with the hurricanes. Some ideas in the video were to drag an iceberg in the hurricane's path to cool the water. Gates and scientists want to pump warm water down and cold water up. We do not know if this is realistic yet but it is being tested. They believe that physics is accurate but don’t know if when put to scale the pump/barge will function right.
