"Power up for a Brighter Future"

     "This is RBS (Robust Broadcasting Station) News. We come to you today, February 14, 2150, from Robust -- an underwater city supported internationally and made up of people from many nations. Energy resource problems have been ignored for centuries. Non-renewable fossil fuels are running low. Breakthroughs are beginning to show potential in solving the world's energy generation needs. Let's listen in:"
      "We, the Robust Delegation would like to present our design of a new system for energy generation. Before we established our city, we employed geologists as well as engineers from different disciplines to determine how to use resources accessible from the ocean to produce energy. A summary of our system is being beamed to you by the very energy their methods have produced."
      "The primary source of energy is geothermal conversion of heat to electricity. Seawater flows down a funnel into the heat exchange area where the water is vaporized because of the great heat from the magma under the surface. As the water comes down the funnel, it turns a hydraulic turbine, which generates huge amounts of electricity. In turn, we also generate vast amounts of electricity from the vapors rising and turning a gas turbine."
      "During the development process we encountered several challenges. The funnel structure and material had to be non-corrosive and capable of surviving under the severe pressure of the deep sea. Teams of structural and material engineers worked together and developed CMC (Carbon fiber-Metal-Carbon fiber) sandwich materials. The core metal provides strength while the stiff carbon fiber offers protection to the metal from corrosion."
      "Another example of a challenge was high-temperature piping required for the geothermal heat-exchanger. Our material engineers developed high-temperature ceramics similar to those used in the space shuttle tiles."
      "The extreme heat also made it impossible to drill with mechanical drilling heads. Scientists of physics and civil engineers joined to create a laser-drilled tunnel. We also employed mechanical engineers to design and maintain turbines, electrical engineers to monitor generators, and computer engineers to be responsible for system control."
     "We chose geothermal over current energy sources for many reasons. Geothermal is a renewable source, requires no energy to start up, is non-pollutant, inexpensive, and is easy to acquire. Fossil fuels on the other hand are not only running short, but produce pollution, requires energy to start up, and is expensive. Nuclear energy, though productive and cheap, is a hazard to people. Solar and wind are both renewable, inexpensive, and don't need the energy to start up, but are too weather-dependant. For these reasons, relying on geothermal is a choice to behold."
     "This has been RBS News. The Robust Delegation and its team of engineers have plans for many more of these geothermal systems that have the power to supply the earth with energy! Stay tune on this exciting technology of energy generation."
