As our time at EARTH University comes to an end, many of us are sad about leaving all of the international friends we have made during our stay here. I have met so many interesting and hilarious people from all over the world and finding an environment like this would be almost impossible.
Today, we visited the Reventazón Hydroelectric Dam & Power Plant. We toured the facility, asked many questions, and took scenic photographs.
After lunch back at the university, we had a lecture by Dr. Camp on energy found in the ocean such as gas, petroleum, methane hydrates, tidal, wind, solar, and waves. We also learned that for every source of energy harvested, there is a tradeoff that has to be met. No energy source is 100% problem free, but that doesn't mean solutions can't be engineered to improve current technology.
After the lecture, we planted a tree called a "Miracle Tree" that produces fruit that is sour and then sweet. This is the third trip to EARTH University by Massachusetts Maritime Academy, therefore the third tree planted at this campus. Maybe one day some of us will come back to visit our tree and see how much it has grown.
After this, we were given free time and later that night we had a two hour game of water polo with some of the Earth University (and three goals were scored by yours truly).
Tomorrow we will be saying goodbye to our new friends along with the University, and going to the Bri Bri indigenous community of Costa Rica for one night.
So far, it's been so much fun here in a different country, and all of our Spanish is improving!
