Portable chargers By: Saud, Jose, and Cody
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
The parts that we should get: • A 6v 50mA solar cell • Project box (5x2.5x2) • 12VDC car power outlet socket • Velcro
Where to get it from: • We can disassemble a solar powered calculator • Or we can get everything from Radio shack for a cheap price
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: • It is comparatively small. It can fit in pants pockets. • It should not weigh more than 0.5 kg. • Safety: • Since it is not transmitting any harmful waves’ it should not be unsafe for anyone to use it. • Also, it will not overheat . So the ski will not burn if it is placed in the pocket.
Other Related Info. (2) • Impact on environment: • Solar energy is the safest and most effective source of energy. • 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.
Other Related Info. (3) • Economic viability: • It could be expensive when you guy and install it. However, it is very economical in the long-run. • It is a renewable source of energy. So you don’t need to buy new batteries every time you run out of energy.
Wind Energy • No need for batteries. • Most efficient at sea. • Renewable. • Reliable. • Completely natural. • Can produce 5 Megawatts of energy.
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 #6 x1 • Mini hub cover x1 • Mini hub base, motor mount x1 • Nut #10 x1 • 1.5 V motor x1 • Mini motor mount x1 • 15 cm (~10 in) skewer x10
Parts that we should get (2) • Tape • Material for blades
Other related info. • Ease of use: • It shouldn’t be hard to use, since you basically just hold it opposing the wind. • Size and weight: • It is not as small and as portable as the solar generated charger. • Safety: • It is not as safe as the solar generated charger.
Other related info. (2) • Impact on the environment: • It is wind generated. That means that it is not omitting any pollutants. • Good for wild life. • Estimates say that just (0.0001%) of bird fatalities are caused by wind turbines. Which means that household cats are more dangerous to them. • Wind energy produces energy without omitting any green house gases. So, it does not develop global worming.
Other related info. (3) • Economic viability: • Wind parks help the communities that host them economically. • 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. • Wind parks create a lot of jobs.
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.
