1. PORTABLE CHARGERS BY: SAUD, JOSE, AND CODY

2. SOLAR PANELS No need for any batteries No need for on/off button(s) Used everywhere nowadays: sunglasses to electric vehicle charging station In hot sunny day the sun can omit over 1000 watts of energy Made of semiconductors such as silicon

3. THE PARTS THAT WE SHOULD GET: A 6v 50mA solar cell Project box (5x2.5x2) 12VDC car power outlet socket Velcro

4. WHERE TO GET IT FROM: We can disassemble a solar powered calculator Or we can get everything from Radio shack for a cheap price

5. OTHER RELATED INFO. Ease of use: No need to turn on or off to use. It will not loose any energy if we leave it on. Size and Weight: 1.It is comparatively small. It can fit in pants pockets. 2.It should not weigh more than 0.5 kg. Safety: 1.Since it is not transmitting any harmful waves’ it should not be unsafe for anyone to use it. 2.Also, it will not overheat. So the ski will not burn if it is placed in the pocket.

6. OTHER RELATED INFO. (2) Impact on environment: 1.Solar energy is the safest and most effective source of energy. 2.It enhances sustainability: like the solar powered home at PSU.  most of the tiles on the side walls and the roof are solar panels.  It competed in a national competition for the most sustainable homes.

7. OTHER RELATED INFO. (3) Economic viability: 1.It could be expensive when you guy and install it. However, it is very economical in the long-run. 2.It is a renewable source of energy. So you don’t need to buy new batteries every time you run out of energy.

8. WIND ENERGY No need for batteries. Most efficient at sea. Renewable. Reliable. Completely natural. Can produce 5 Megawatts of energy.

9. PARTS THAT WE SHOULD GET Perpendicular block x2 30 cm (~12 in) dowel x2 Hole plate x1 5/8 screw #10 x1 5/8 screw #6x1 Mini hub coverx1 Mini hub base, motor mount x1 Nut #10x1 1.5 V motor x1 Mini motor mount x1 15 cm (~10 in) skewer x10

10. PARTS THAT WE SHOULD GET (2) Tape Material for blades

11. OTHER RELATED INFO. Ease of use: 1.It shouldn’t be hard to use, since you basically just hold it opposing the wind. Size and weight: 1.It is not as small and as portable as the solar generated charger. Safety: 1.It is not as safe as the solar generated charger.

12. OTHER RELATED INFO. (2) Impact on the environment: 1.It is wind generated. That means that it is not omitting any pollutants. 2.Good for wild life. 3.Estimates say that just (0.0001%) of bird fatalities are caused by wind turbines. Which means that household cats are more dangerous to them. 4.Wind energy produces energy without omitting any green house gases. So, it does not develop global worming.

13. OTHER RELATED INFO. (3) Economic viability: 1.Wind parks help the communities that host them economically. 2.It generates a huge amount of energy in windy places( e.g. Chicago) that you can sell in wholesale. In which case can help both the consumer and the seller. 3.Wind parks create a lot of jobs.

14. HOW TO CONNECT MY TWO POWER SOURCES? Base with a solar panel facing upward. A hole in the middle to place the wind turbine neck. And the fan itself can be removed from the neck to allow for easier transportation when trying to move from one place to another.
