What is the Most Green and Sustainable Way to Charge an iPod?
Procedure
1. Set-up
a. Clear all iPods
b. Create a playlist with at least 2 hours plus of music time
c. Upload the same playlist to each iPod
d. Listen or “waste” power on all of the iPods until they die and cannot turn on
e. Create a data table on Microsoft Word and save it so you can plug in your data electronically, saving paper
f. Charge the iPod for ten minutes from the wall charger for each iPod and record how much audio playback you receive. Repeat this two more times totaling three trials for each iPod. Average this and record all data. This will be used later on.
2. Solar Power
a. Charge the solar panel outside for 30 minutes. Lay the panel in a sunny spot on a flat surface. Also, charge the iPod nano from the wall for ten minutes and shut the iPod off on hold.
b. After 30 minutes, plug the iPod nano into the iPod cable and charge the iPod
c. Record the amount of battery it has when finished charging
d. Repeat steps 2.a-b two times more
e. Repeat steps 2.a-c for iPod Classic
f. Make sure that you charge the same iPod at the same time in different days, with the same amount of sunlight
3. Hand Crank
a. Charge the iPod nano from the wall for ten minutes.
b. Plug the iPod into the Dynamo Hand Crank USB Charger.
c. At a rate of 60 cranks per minute, crank the device for 30 minutes.
d. Record the amount of battery it has when finished charging.
e. Repeat steps 3.a-b two times more.
f. Repeat steps 3.a-c for iPod Classic.
4. Lemon Battery
a. Charge the iPod nano from the wall for ten minutes and turn the power off, and on hold.
b. Roll the lemons on a steady surface to break up the juices inside. Cut four lemons into equal fourths.
c. Make sure that the lemons are room temperature.
d. Stick the zinc and copper directly into the lemons and make sure they are not touching. Also, try t submerge the copper in the lemon for best voltage.
e. Connect a zinc metal in the lemon to a copper metal with the alligator clip jumper cables in another lemon. Continue with this until all metals are connected except for one zinc washer and one copper penny in two different lemons.
f. Then, cut your USB off of the dock cable and strip an inch of the wire off.
g. Push the fabric, metallic, uninsulated wires on the outside down and out of your way. Then tare the layer of insulation off. After, push the yellow string down also.
h. You will then have four wires: green, white, red, and black. Strip the red and the black wires and move the others out of your way. Connect the copper with the alligator clips to the red wire. Connect the zinc with the alligator clips to the black wire. Hook up the voltage regulator y its instruction manual.
i. Measure the Voltage of the Battery and record.
j. Plug the charger into the iPod.
k. When finished charging, record the amount of battery. Dispose of lemons properly as in compost.
l. Repeat steps 4.a-j two more times.
m. Repeat steps 4.a-k with iPod Classic.
5. Voltaic Pile
a. Heat soldering iron.
b. Charge iPod nano from the wall for ten minutes.
c. Cut the aluminum wire in half, and solder one wire to a penny and one wire to a galvanized washer. These will be your ends of your voltaic pile.
d. Cut out 30 penny sized discs of blotter paper or cardboard and soak them in lemon juice.
e. Then, solder a wire to a copper side of a penny and to a zinc side of a penny. These will be your end cells.
f. Next, align the pennies, washers and paper in this pattern: penny-washer-paper-penny-washer-paper; until the materials run out. Make sure that your soldered penny and washer are on the opposite ends.
g. Use the rubber band to hold the battery together.
h. Then, cut your USB off of the dock cable and strips an inch off the wire.
i. Push the fabric, metallic, uninsulated wires on the outside down and out of your way. Then tare the layer of insulation off. After, push the yellow string down also.
j. You will then have four wires: green, white, red, and black. Strip the red and the black wires and move the others out of your way. Connect the soldered wire connected to the copper with the alligator clips to the red wire. Connect the soldered wire connected to the zinc with the alligator clips to the black wire.
k. Measure the Voltage and record.
l. Plug the charger into the iPod.
m. When finished charging, record the amount of battery.
n. Repeat steps 5a-k two more times.
o. Repeat steps 5.a-l with iPod Classic.
6. Wind
a. Charge the iPod for ten minutes from the wall.
b. Stand your Hymini Wind Charger so that the blades are facing the fan.
c. Leave the box fan pointed at the turbine for 30 minutes on medium. Make sure that the Hymini is glowing green and charging. The wind speed should be about 30 km/h.
d. After 30 minutes, charge the iPod nano.
e. When finished, record the amount of battery in the iPod.
f. Repeat steps 6.a-d two more times.
g. Repeat steps 6.a-e with iPod Classic.
7. AC Charger/ Wall
a. Connect the USB cable and power adapter.
b. Insert the iPod cable into the iPod nano.
c. Plug the adapter into the wall outlet for 30 minutes.
d. After 30 minutes of charging, record battery life.
e. Repeat steps 7.a-c two more times.
f. Repeat steps 7.a-d for iPod Classic.
8. Order
a. First, start with the solar power, only one charge per iPod a day because of the time. If not, variables would be off because of the different rays of sunlight.
b. Next, the lemon battery, this can be done in all different days or in the same. Make sure that you do not use the same lemon twice and that everything is the same temperature.
c. After, the voltaic pile, this can also be done in all different days or all in the same day. Just be sure to check the temperature of the lemon juice and make sure that the coins are clean.
d. The wind turbine is next. This experiment can be done in all of the same day or spread out. Just make sure that the fan is always on the same speed.
e. Lastly, the AC or wall charger does not matter what type of day or different day you do it in. Just remember to charge from the same outlet because all outlets are different
9. Data collection
a. Since there is no way of telling the percentage of battery life on an iPod nano and iPod classic, we have to listen to music nonstop until the iPod dies. This tells which way of charging the iPod allowed you to listen to the most songs.
b. To make this easier, calculate the songs that are on the playlist and just add up the times of each song that had played.
c. We first add 10 minutes of wall charging time because you should not supposed to let your iPod die and then charge it. It kills the battery. Also, some of the devices that are being used to charge the iPods may not charge without some charge in it device.
d. A fully charged iPod nano 3rd generation will get 24 hours of audio playback.
e. A fully charged iPod classic 5th generation will get 20 hours of audio playback.
a. Clear all iPods
b. Create a playlist with at least 2 hours plus of music time
