EDSGN 100 Group 8
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%.
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.
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.
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.
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.
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.
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.
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
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.
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
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 Hydrogen Fuel
Environmental Managementen.wikipedia.org/wiki/enviornmental-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 processes—if 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).
