Vitality:

The Power to Live and Develop
Design and Generation of Energy

     Welcome to Vitality, where a portfolio of renewable energy resources assures inexpensive power. Environmental engineers identified natural geographical benefits of Vitality such as high winds, shoreline, abundant sunlight and farmland. Then civil, mechanical, aeronautical, chemical and other engineers developed power systems for our energy portfolio. This portfolio includes solar, wind, wave, bioenergy, and fusion, along with insulators to maximize efficiency.
      Photovoltaic cells, solar panels, are two layers of silicon with a chemical substance, gallium arsenide between them. When this chemical heats, electrons rapidly flow into a wire, creating an electrical current. With plentiful sunlight, panels on buildings are effective.
      Vitality's winds rotate turbines connected to shafts, which cranks generators, producing electricity. There are excellent reasons to harness wind energy for power; "…wind energy generates pollution-free electricity…and costs continue to drop as technology improves." The shorelines allow us to utilize wind power through waves. "Waves are a free and sustainable energy resource created as wind blows over the ocean surface." Collectors harness wave action in a chamber along the shoreline, forcing compressed air into a turbine. The turbine's action then transfers to a generator, which creates power.
      Our large farmlands supply methane gas, creating bioenergy. Methane can be collected from the following: "renewable plant materials such as sawdust, tree trimmings, rice straw, alfalfa and switchgrass; poultry litter and other animal wastes; industrial waste; and the paper component of municipal solid waste." A specific bioenergy, biodiesel, can be used in vehicles as fuel. "Converting vegetable oils or animal fats into diesel fuel creates biodiesel." Although "burning a human food resource for fuel… raises important ethical and moral issues", biodiesel fuel can power farm machinery to help produce more food.
      Although our city plans to use renewable energy sources, our engineers concluded that a consistent and reliable power source was needed. "Fusion power offers the potential of an almost limitless source of energy for future generations." Fusion power is the rate at which hydrogen is converted into electricity by the theory of mass turned into radiant energy ð heat ð steam ð motion ð electricity. In Tokyo, scientists produced plasma, but have difficulty maintaining it due to constant need for a consistent magnetic field. Two isotopes of hydrogen (deuterium and tritium) heated separately with immense heat, made by the fission process or by collapsing a magnetic field, create plasma. When the two hydrogen isotopes are combined, they loose mass and the lost mass becomes thermal energy. The heat boils water and steam that is produced turns a turbine, producing electricity.
      To conserve the energy produced, Aerogel, "the lowest density product ever produced", consists of 99% air and is used to insulate our buildings. Aerogel is "formed by extracting the liquid from a micro structured gel."
     With this portfolio of energy resources, Vitality lives up to its name and continues to generate power, propelling itself into a brighter future.
