Problem 1.4.1 Renewable Electrical Energy Generation and Distribution Define The Problem Design and create a renewable electrical energy generating distribution system that utilizes wind, solar, electric, and fuel cell energy. Brainstorm Generate and Research Ideas The next step was generating these crazy ideas onto paper and start to visualize the brainstorm into possible ideas.
We then researched things like;
How to turn a motor into a generator.
Advantages of parallel versus series circuits.
The most useful ways to use solar panels in a circuit. Identify Criteria and Specific Constraints Criteria/Constraints
The distribution system must run for a simulated 24 hour cycle (6 minutes in real time).
Dimensions must fit 22 in. by 15 in. by 18 in. high.
2 Fuel cells, 2 Solar panels, Turbine (student created)
A motor is in place for the generator.
LED's must represent both Residential (Red LED) and Industrial (Yellow LED)
LED's must be wired in series and require a 330 Ohm resistor.
No Sun is applied to solar panels during the night period.
The lights MUST glow the whole time. Explore Possibilities The next step was to start accepting and approaching the REALISTIC possibilities.
These realistic possibilities included ones that were within our team's structural building talent and our electrical talent. Select an Approach Develop a Design Proposal Make a Model or Prototype Test and Evaluate the Design Using Specifications Refine the Design Create a Solution Communicating Process As a group we sat down and generated ideas.
Have a large wheel so two people at one can time can generate energy.
A large gear to small ratio for better mechanical advantage.
The solar panels organized in a way to attract most sunlight without wasting any sun (center the panels)
Organize the turbine, solar panels and the fuel cells on one side of the 22 in. by 15 in. VEX board.
Organize the industrial and the residential circuits in a series fashion and totally separate from each other.
Each industrial and residential section have their own solar panel and fuel cell while the wind turbine is shared.
The solar panels are wired through the fuel cells so while charging the fuel cells the solar panel is running the lights. After plenty sketches of electrical and structural designs our team agreed on an approach.
This approach would stay within the constraints and complete the given task. Final Sketches. (Isometric and Electrical) Our team created a proposal. Our design would;
1. Meet all constraints
2. Solve and complete the given problem
3. Be wired in two separate series circuits.
4. Series circuit A would include 4 Residential LED's and 3 Industrial LED's. Circuit A would run off of the wind turbine and one solar panel during daylight.
5. Series circuit B would include only two Industrial LED's. Circuit B would run off of both fuel cells and one solar panel during daylight. We created a 3D model and started to wire the circuits on the breadboard.
Creating the Model took one week. Pictures of our Model Residential Voltage Requirement: 1.5 V
Industrial Voltage Requirement: 1.5 V
Resistance Requirement Industrial/Residential: 330 Ohms Electrical Requirements Test Results Generator (Motor)
Voltage Output: 13 Volts
Current Output: 3mAmps
Voltage Output: 2.7 Volts
Current Output: 5.6mAmps
Voltage Output: 3 Volts
Current Output: 2.09mAmps The only refining that was done to our distribution system was that more bulbs were added to the circuit in order to utilize as much of the created electricity as possible. So, a solution was created in which 9 total bulbs (5 Industrial yellow and 4 residential red) were lit for the entire 24 hour simulation.
Electricity was distributed evenly throughout our system.
Our electrical distribution system would and could power a city for a whole 24 hour day through night and day. Communicating with possible costumers would include a power point or presentation that shows how the 24 hour simulation distribution system works. The presentation would also include pictures and persuasive advertising that pushes possible customers closer to purchasing the idea and rights to the 24 hour simulation distribution system.
