may not be able to create large amounts of renewable energy from the sun or from a wind farm, but there may be a new for of renewable energy. However, being a collection of islands, it does have thousands of miles of coastline which contains tides going up to 18 mph. An upside to using water instead of air, with the increased density compared that of air, it requires less surface area to create a spin with the blade, it will require less space per wheel. Another useful benefit is the turbines are underwater, and would not block the beautiful view outside into the ocean. 

NASA making history once again

Earlier this morning, at 7:05 a.m. PST, at the Space Launch Complex 37 at Cape Canaveral Air Force Station in Florida, Orion was launched into space. The project costed NASA $350 million this week alone. Upon reentry to Earth's atmosphere, the capsule was going at an incredible rate of 20,000 mph while experiencing temperatures over 2204º Celsius (4,000º Fahrenheit).
The test flight took 4 hours and 24 mins stated NASA. The capsule had landed off the coast of Baja California in the Pacific Ocean at 10:29 a.m. EST. Reaching heights over 3,604.2 miles, 15 times the height of the International Space Station at 268 miles in orbit. During it's flight, it had encircled the Earth twice
