2011-02-24 - Energy and Transportation Systems

posted Feb 24, 2011, 5:44 AM by Nick Formica   [ updated Mar 1, 2011, 5:33 AM ]

For this assignment you are to determine if your selected energy/power or transportation technology is truly a viable alternative to traditional(or your compared) energy systems.
  1. Define the problem - Our current consumption of resources is staggering, does (your technology) help reduce our impact on the environment enough to justify using it over what we traditionally use or does it provide a compelling set of advantages over the more environmentally friendly alternatives?
  2. Research and investigation - research similar problems and existing commercial solutions (at least 5)
  3. Generate comparison - list as many differences (examples where your technology can make a difference) as possible (at least 7) and describe the most important two.
  4. Detailed plan - create a plan/proposal using one of the following formats:
    1. Presentation using a web tool other than power-point-choose from below or ask
      1. www.prezi.com - visual presentation alternative
      2. sites.google.com - website
      3. www.mywebspiration.com - mind mapping software
    2. Video
      1. www.stupiflix.com
      2. any other creation software you can use (ie. movie maker)
    3. 3D poster
    4. Practical solution/prototype (something we can implement)
  5. Evaluate - critique your classmate's proposals using the supplied rubric and make improvement suggestions
  6. Redesign - review your classmate's suggestions and write a reflection on indicating what you would keep, change, or remove from your chosen solution and presentation.

2011-01-05 - Household Wiring

posted Jan 12, 2011, 1:10 PM by Nick Formica   [ updated Jan 12, 2011, 1:34 PM ]

Your home consists of parallel circuits of alternating current.  This means that each device acts independently from one another (in ideal circumstances).  Switches and breakers are connected in series with the loads in a household for control and protection.  The series switch/breaker breaks the electrical connection from the hot side of a circuit.

Hot wire - black or red - this the the "dangerous" wire
neutral wire - white - this wire completes the circuit at the electrical box
ground wire - protection wire in case a hot or neutral wire slips off terminal and does not trip the breaker

The neutral and ground wires are connected together at the electrical box.  From there, a connection is physically made to the earth typically via a water pipe or copper rod.



Please review the attached documents for additional information.
