Slide-22

Despite the mounting costs of climate change and inevitably declining oil, natural gas and uranium reserves, the vast majority of cities and urban communities is planned and managed as if such existential crises did not exist. Hence the transition from fossil fuel dominated cities to an urban future marked by a radically new, renewable energy infrastructure requires entirely new tools and frames of decision-making.

The increase in global warming awareness among the world population has pushed the renewable energy industry to another plateau. The race for a conducive and sustainable environment will be the future direction the energy industry is heading for. In the next decade it is anticipated that 50% of the energy usage will come from the renewable sector. Sustainable energy will be applied in areas for motoring, domestic use and even commercial and industry. The idea is to have an almost total renewable energy application within a city.

Type of renewable energy identify in our project:

  • Solar Energy

    • Solar Thermal Energy (Parabolic trough designs)

      Solar_ArrayParabolic trough power plants use a curved trough which reflects the direct solar radiation onto a pipe containing a fluid (also called a receiver, absorber or collector) running the length of the trough, above the reflectors. The trough is parabolic in one direction and straight in the other. For change of position of the sun perpendicular to the receiver, the trough tilts so that the direct radiation remains focused on the receiver. However, a change of position of the sun parallel to the trough does not require adjustment of the mirrors, since the light is simply concentrated elsewhere on the receiver. Thus the trough design does not require tracking on a second axis.

      The receiver may be enclosed in a glass vacuum chamber. The vacuum significantly reduces convective heat loss.

      A fluid (also called heat transfer fluid) passes through the receiver and becomes very hot. Common fluids are synthetic oil, molten salt and pressurized steam. The fluid containing the heat is transported to a heat engine where about a third of the heat is converted to electricity.

    • Solar Photovoltaics (PV)

      solarpvPhotovoltaics are best known as a method for generating electric power by using solar cells to convert energy from the sun into electricity. The photovoltaic effect refers to photons of light knocking electrons into a higher state of energy to create electricity. The term photovoltaic denotes the unbiased operating mode of a photodiode in which current through the device is entirely due to the transduced light energy. Virtually all photovoltaic devices are some type of photodiode.

      Solar cells produce direct current electricity from light, which can be used to power equipment or to recharge a battery. The first practical application of photovoltaics was to power orbiting satellites and other spacecraft, but today the majority of photovoltaic modules are used for grid connected power generation. In this case an inverter is required to convert the DC to AC. There is a smaller market for off grid power for remote dwellings, roadside emergency telephones, remote sensing, and cathodic protection of pipelines.

      Cells require protection from the environment and are usually packaged tightly behind a glass sheet. When more power is required than a single cell can deliver, cells are electrically connected together to form photovoltaic modules, or solar panels. A single module is enough to power an emergency telephone, but for a house or a power plant the modules must be arranged in multiples as arrays.
  • Wind Power

      • Wind Turbine

        windWind power is the conversion of wind energy into a useful form, such as electricity, using wind turbines. Wind energy as a power source is attractive as an alternative to fossil fuels, because it is plentiful, renewable, widely distributed, clean, and produces no greenhouse gas emissions.

        A wind turbine is a rotating machine which converts the kinetic energy in wind into mechanical energy. If the mechanical energy is used directly by machinery, such as a pump or grinding stones, the machine is usually called a windmill. If the mechanical energy is then converted to electricity, the machine is called a wind generator, wind power unit (WPU), or wind energy converter (WEC).

      • Aero Wind Power

        aeroaero01AWP is a flying vehicle using helium gas and a very dedicated system to produce the ever-continuing and stable electric power at the altitude of about more than 300m in the air with a higher efficiency than other wind power system, which is a new method to produce clean energy with low expenses.

        AWP is the system producing the electric energy by spinning a wind turbine with the influx of air speedily by using the tunnel of the middle part after manufacturing two balloons floated by helium gas in the form of a catamaran ship and locating the space with a generator installed in the middle horizontally toward the blowing of the wind.
  • Hydropower

    hydraulicHydropower, or water power is power that is derived from the force or energy of moving water, which may be harnessed for useful purposes.

    Prior to the widespread availability of commercial electric power, hydropower was used for irrigation, and operation of various machines, such as watermills, textile machines, sawmills, dock cranes, and domestic lifts.

    Another method used a trompe, which produces compressed air from falling water, which could then be used to power other machinery at a distance from the water.
