Jumpstart2011 city challenge6 - group 55

  1. 1. The UnpredictedDoomsday.<br />Jumpstart 2011<br />
  2. 2. The Scenario<br />The Survivors:<br />Tom Gardiner<br />Will Hector<br />Jake Hodges<br />Type of Zombie: I Am Legend<br />Statistics<br />Duration of apocalypse: 14 days<br />Speed: Fast (8-10 mph)<br />Quantity: Low (4-5 Zombies per street)<br />Intelligence: High<br />Weakness: Sunlight<br />
  3. 3. Map of Locations:<br />
  4. 4. Bad Locations<br />Palmerston Park - Leave<br /><ul><li>Reasons:
  5. 5. No protection at night
  6. 6. Nothing worth protecting</li></ul>Zombie Attack!<br />Avenue Campus - Leave<br /><ul><li>No long term sources of food</li></li></ul><li>Bad Locations<br />Maths Building - Leave<br /><ul><li>No long term sources of food
  7. 7. Windowless areas on the inside – Zombie hiding.</li></ul>Lover’s Lane - Leave<br /><ul><li>No protection at night
  8. 8. Lot’s of dark hiding places for Zombies</li></li></ul><li>Bad Location<br />London Road - Leave<br /><ul><li>Very hard to secure at night due to many entrances and exits.</li></li></ul><li>Protected Location<br />Marlands Shopping Centre<br />Protected!<br />Security shutters to help keep out zombies at night<br />
  9. 9. Resources<br />Food and drink available from several stores such as Poundland<br />
  10. 10. Resources<br />Lots of weapons available<br />
  11. 11. Defence Plans<br />Advantages:<br /><ul><li>Use UV lights from the Sun Beds in the tanning salon in the roof light to keep Zombies away.
  12. 12. Use CCTV system to be able to quickly locate break ins and problems.
  13. 13. Food and other supplies available.
  14. 14. Lot’s of places to retreat to and mount a defence if necessary.</li></li></ul><li>Power<br />Sorry for the essay the next few slides but there's a lot of detail needed.<br />Power, this is a problematic subject as most of our primary defence plans rely on it. However we can safely assume that, at least initially, power should be available because of the size of the building and that most cables are underground within several miles of the area. The time power should continue being available will depend on the extent of the zombie invasion, if it is merely Southampton then we should expect over a week maybe even two weeks. If it is the entire nation then we can only expect a day or two.<br />However there are still backup plans if the power does fail; firstly we will still be able to mount an effective defence using items as barricades and the zombies will first still have to penetrate the outer building when it is locked down. Secondly we can use power from the cars in the car park (Nearby as Marlands does not have its own), see next slide for more info on that.<br />
  15. 15. Power Calculations<br />Warning, This contains loads of assumptions and I probably did some maths wrong but I threw it in anyway for a laugh (It was late).<br />Assuming that say 300 cars in the car park, each with a 12v Lead-Acid battery, and let’s say they have an average of 50Ah and are fully charged. That’s 15kAh at 12v so 180kWh which over two weeks is only 12.8kWh, this isn’t much but assume night is 8hrs then that means we can draw 1.6kW for 8 hours, for 14 days. (We could use an inverter if found or just link 20 in series :D)<br />A typical florescent for a sun bed is 100W, so simple that means we can run only 16 which isn’t much.<br />However we also have the ability to charge the batteries from the cars engines. Now I’m going to assume that if we can’t hotwire a particular car then the fuel can be drained into one we can successfully. <br />
  16. 16. More Power Calculations<br />So apparently the efficiency of charging a Lead Acid Battery is 80% (Google); and due to voltage drop the battery will need to be re-charged when it is 10% charged. The total charge for a 50Ah battery is 2.16MJ, so that’s 1.9MJ to be charged, /.8 (For efficiency) is 2.4MJ. So a car engine is only about 20% efficient but the amount actually charging the battery is probably about say 5% (Worst case scenario).<br />So that means we need 48.8MJ or energy from the petrol; now Petrol contains about 35 MJ/L thus assuming on average the tank has 20L in it we can charge the battery 14 times.<br />However this is high speculative and makes lots of assumptions but we should at least be able to charge the batteries a few times…<br />
