== Background ==
As the need for [[Image:Easy ridas 040 resizedrenewable energy]] has become more apparent to the concerned public, we have discovered ways to wean ourselves off our dependence of fossil fuels and nuclear power.JPGOur team has designed an alternative way to convert kinetic energy to AC power by means of a bicycle energy generator. With this, the [[WaterPod]]as well as others can use our design to generate their own electricity. <ref>Erickson, Ben. (2008) “Human Powered Energy Generator” May 5, 2009. []</ref>

== Abstract ==
''The Bicycle Energy Generator will use kinetic energy supplied through a mechanical system and return usable DC power by means of a direct current energy generator. [[Direct current]] will then run through an electrical circuit and eventually be stored in a bank of marine batteries. This battery bank will provide a source of usable energy for the Water Pod community.''<ref>“The Pedal-A-Watt Stationary Bike Power Generator” May 6, 2009. []</ref>

The name of the final design is “The Bicycle Energy Generator.” This design for the WaterPod project provides to be the solution to meet their criteria and electrical needs. This design is different from the alternative designs because it includes a prefabricated stand and a generator shaft with the bike wheel in the design. A prefabricated stand is a very practical component to this design because it safely holds the bicycle’s back wheel off the ground, allowing it to spin freely, and act as framework for other components of the system. The prefabricated stand is designed to attach at the axle of the back wheel. The axle extends out on either side of the bike wheel so that it rests inside a specially designed shaft of the stand and is locked into place.
The factory-made resistance roller was modified so that it would roll with the DC motor shaft. The resistance used for training was removed and replaced with the generator. The generator shaft is coupled with the roller shaft, so when the roller is spun by the bike tire, the generator shaft is also rotated.
The circuitry of the system runs direct current electricity from the generator to a bank of marine batteries which then can be used to power appliances. Before that happens, as soon as the electricity is exerted by the generator, the [[current]] passes through an amp meter so the user can view what they are producing. The current is then passed through a blocking [[diode]] in order to prevent the current from running in reverse. Then, it passes through a 13V voltage regulator so the [[voltage]] does not exceed the determined capacity of the battery. Finally, the current is sent directly into a battery bank where usable energy is stored for later consumption. In order to maintain a functioning electrical circuit, the current returns through the battery and back through a fuse. After the current passes through the voltage regulator again, the direct current passes through a final fuse and completes the circuit.<ref>“Bicycle_Powered_Generator” May 6, 2009. []</ref>

Although we chose to use a prefabricated stand, with the direct contact roller method, there are other components that can work as well.
Instead of using a prefabricated stand one can choose to build a custom built stand.
We chose the Direct Contact Roller but the pulley system will work as well[[Image:Pulley.jpg|400px]]
We used chose the Spring Design, Direct Contact Roller but the Swing Arm Design is adequatepulley system will work as well. <ref>Erickson, Ben. (2008) “Human Powered Energy Generator” May 5, 2009. []</ref>

== Costs ==
* Bicycle: A road bike with small threads is preferred
* Bicycle StandTrainer: Look on or retail stores onlinefor cheap/used trainers* 12V DC motorMotor: A convenient place to purchase is at Alternative Power, Inc in Arcata, CA
* Inverter: any hardware store
* 12 V marine batteryMarine Battery: Look online for the most convenient buy* Two Fuses: can be purchased at RadioShackHarbor Freight or local hardware store
* Diode: Use a blocking diode found at any local hardware store
* 7 amp regulator: purchase at a local hardware storeor online* Wiring: use a 12 gauge or smaller, 12 feet long, ; purchase at local hardware store
* Scrap metal: any scrap yard
2. Construct motor/roller
* To connect your DC motor to your bicycle trainer flush with the resistance roller, you must examine both the resistance roller to see if shaft and the motor shaft to see if they can be coupled with the roller* Deconstruct your roller so that the roller shaft can be coupled with the motor shaftwithout any interference* Couple the two shafts together, a rubber couple would be best if the two shafts are not in equal in width
* Investigate where the motor should be placed, so that you can mount it to the bicycle stand
* Mount The first part of the motor by placing mount is a piece of metal between the mounted resistance roller and the spring loaded boardof the bike trainer.* The second part of the mount is holding the motor in place.* Construct a mount that will hold motor in place, preferably two perpendicular, horizontal pieces of metal slightly on either side of the motor as shown below. These are welded in place by a vertical piece, that is also welded (at a 90 degree angle) to the first piece of metal that is bolted down by the roller shaft and the spring board. The motor may vary in size so there are no dimensions givenfor this mount, but the general idea is to mount the motor so that it will not move once coupled with the roller. [[Image:Motordiagram.jpg]]
3. Build electrical circuit
* Here is a diagram of what needs to included in the circuit* Use soldering gun to connect fuses, diode, voltage, regulator, battery, and inverter. Clamps are also acceptable to connect pieces of circuitwhile testing.
** First slip a sleeve of shrink tape over one wire and slide it out of the way of the soldering gun.
** Hold wires together(make sure you use proper protection) and solder the wire ends together.
** Once wires are connected, slide shrink tape over exposed wires and used a flame to tighten the tape.
** Repeat this step for any wires that need to be connected to complete the circuit to the diagram<ref>Erickson, Ben.(2008) “Human Powered Energy Generator” May 5, 2009. []</ref>
