  • Group 8

2
Advances In Sports Medicine
  • Now, athletes can heal faster because of a new
    surgery called keyhole surgery.
  • It reduces scarring by making several small
    incisions instead of one large one.
  • Just 12 days after undergoing this surgery,
    Australian sprinter Jana Rawlinson was able to
    compete in the Olympics (Sydney Morning Herald).
  • With technology like keyhole surgery and stem
    cell technology, athletes are missing less time
    on the field while still rehabbing to 100.

3
Other Advances In Medicine
  • The genome of the mosquito has been sequenced to
    help to find a cure for malaria.
  • Blood tests can now reveal cancerous DNA from
    healthy DNA.
  • Doctors can now consult advanced computer
    programs to help diagnose patients.
  • One example is the program Isabel, which lists
    several different diseases and ailments when
    symptoms are typed into its database.

4
Solar Energy
  • 1. Solar Cells-convert light directly into
    electricity, such as calculator.
  • 2. Solar Water Heating-where heat from the Sun
    is used to heat water in glass panels on your
    roof.
  • 3. Solar Furnaces-use a huge array of mirrors
    to concentrate the Sun's energy into a small
    space and produce very high temperatures.

5
Advantage/Disadvantage
  • Advantages
  • Solar energy is free - it needs no fuel and
    produces no waste or pollution.
  • Handy for low-power uses such as battery chargers
  • Disadvantages
  • Doesn't work at night.
  • Very expensive to build solar power stations.
  • Can be unreliable unless you're in a very sunny
    climate.

6
Wind Power
  • 1. It is the energy from the air.
  • 2. We can use the energy in the wind by
    building a tall tower, with a large propeller on
    the top.
  • 3. The wind blows the propeller round, which
    turns a generator to produce
    electricity. The more towers, the more wind, and
    the larger the propellers, the more electricity
    we can make.

7
Advantage/Disadvantage
  • Advantages
  • Wind is free, wind farms need no fuel.
  • Produces no waste or greenhouse gases.
  • A good method of supplying energy to remote
    areas.
  • Disadvantages
  • The wind is not always predictable - some days
    have no wind.
  • Can affect television reception if you live
    nearby.
  • Can be noisy.

8
Nuclear Power
  • 1. It is the energy from splitting Uranium atoms.
  • 2. Nuclear power stations work in pretty much the
    same way as fossil fuel-burning stations.
  • 3. Modern nuclear power stations use the same
    type of turbines and generators as conventional
    power stations.
  • 4. In Britain, nuclear power stations are built
    on the coast, and use sea water for cooling the
    steam ready to be pumped round again.

9
Advantage/Disadvantage
  • Advantages
  • Not expensive to make.
  • Does not produce smoke or carbon dioxide, so it
    does not contribute to the greenhouse effect.
  • Produces huge amounts of energy from small
    amounts of fuel.
  • Produces small amounts of waste.
  • Nuclear power is reliable.
  • Disadvantages
  • It is very, very dangerous.
  • It must be sealed up and buried for many years to
    allow the radioactivity to die away.
  • It takes a lot of money for safety

10
Is it renewable?
  • Solar power is renewable. The Sun will keep on
    shining anyway, so it makes sense to use it.
  • Wind power is renewable. Winds will keep on
    blowing, it makes sense to use them.
  • Nuclear energy from Uranium is not renewable.
    Once we've dug up all the Earth's uranium and
    used it, there isn't any more.

11
Hydrogen Fuel
  • A potential alternative to gasoline
  • Hydrogen is very useful as an energy source in
    its liquid state.
  • Hydrogen fuel is created by taking hydrogen from
    its associated carbon in a hydrogen reformer and
    then feed the hydrogen into a fuel cell
  • When produced using electricity, it is a chemical
    energy storage as in storage batteries
  • A fuel cell can convert the chemicals hydrogen
    and oxygen into water, and in the process,
    produce electricity
  • Hydrogen can be burned in an internal combustion
    engine
  • Less efficient than fuel cell

12
Hydrogen Fuel
  • Pros
  • Non-polluting
  • Hydrogen is the lightest chemical element and has
    the best energy-to-weight ratio of any fuel
  • Hydrogen can be produced anywhere
  • Cons
  • Manufacturing it expends energy
  • Complicated to handle, store, and transport
  • Current fuel cell designs are expensive

Environmental Managementen.wikipedia.org/wiki/env
iornmental-management
  • Environmental management is therefore not the
    conservation of the environment solely for the
    environment's sake, but rather the conservation
    of the environment for humankind's sake.
  • Sustainability essentially means preserving life
    on Earth, including human civilization.
  • Society mines and disperses materials faster than
    they are returned to the Earth's crust Society
    produces substances faster than they can be
    broken down by natural processesif they can be
    broken down at all
  • Society depletes or degrades resources faster
    than they are regenerated (for example,
    over-harvesting of trees or fish), or by other
    forms of ecosystem manipulation (for example,
    paving over fertile land or causing soil
    erosion).
