How often has the battery on your cell phone or iPod died?
Our modern day conveniences come with the burden of having to
recharge the batteries regularly. Instead of having to plug
your phone or iPod into an electrical socket, you can instead
use the power of the sun to recharge it. And if you learn
how to
build a solar powered backpack, you'll have your very
own portable recharging station whenever you need it.
Solar backpacks work by absorbing sunlight and storing the
energy collected into a battery. Whenever your backpack is in
the sunlight -- for example, while you're walking to class,
going on a hike, or just relaxing outside -- you can store
solar power.
The problem with many solar powered backpacks available for
purchase is that they're so small (and costly!). By buying your
own regular backpack, you can choose the size and configuration
that's useful to you. Turning the backpack into a solar powered
bag isn't that hard, either.
The first step in converting your backpack is to purchase a
solar panel charger that fits your pack. Look for a thin, flexible
solar panel charger with a USB cable for connecting to your iPod,
cell phone, etc. You will probably want to get more than one panel,
for maximum impact. Try to find panels that are weather resistant.
Once you have purchased the solar panel(s), you need to connect it to
the backpack. Sew a pouch to hold the panel, and then attach the panel in
its pouch to the side of the backpack that's exposed to the sun (ie.
not the side that rests against your back). That's all there is
to it.
Keep the solar panels clean so that they operate at their most efficient.
Learning how to build a solar powered backpack is a neat idea for students,
travellers, hikers, cyclists, campers, and anyone who spends time outdoors
yet wants to stay connected!
