The article "The Falkirk Wheel" by Alan Bellows introduces the idea of using a pulley system instead of using locks to get a boat from one water height to another. This wheel uses gravity to lower boats from the bridge to the river below. There are two arms on the wheel which are both filled with water and can hold four, 20 yard long boats at a time. The two wheels are very energy efficient using mostly gravity and as a result they only use 1.5 kilowatts per hour. This matters to me because this is a great idea and will inspire future creativity. This matters to the world and education because it should inspire other countries to try to integrate this idea into other countries.

The article "Germany's Pleasure Dome" by Allan Bellows evaluates a dome in Germany that stands 350 feet tall, and encloses 194 million cubic feet of space. Inside this dome is an imitation beach environment with water, a large beach and palm trees. The air temperature is always between 77 and 82 degrees. The combination of heat and water, forms condensation on the inside of the roof and when there is enough condensation it actually rains creating quite an intricate atmosphere inside the dome. The windows allow UV light rays through, mixed with the water and oxygen, let plants grow. This matters to me because if I am ever in Germany and want to go to the beach, I can go to the dome because they let everybody in. This matters to education and the world because this German experiment has furthered our knowledge of growing plants indoors if something happens to our atmosphere that doesn't allow plants to grow.
