Having missed the chance to get my hand on the hand-crank generators due to having to leave class early, I instead explored the usage of Hand-Crank generators. We take electricity and power for granted because it’s all around us. We can charge our phones through an outlet in the wall, through a USB in our computers, and even in our cars. Yet, what would we do if all of a sudden we could not have the luxury of charging our electronics. A Hand Crank Generator is the perfect solution for those who love the outdoors or who want to prepare for the unpredictable things that mother nature throws at us(hurricanes, blizzards, etc). We want to be able to stay connected in today’s society because news is so constant through our phones. A hand-powered generator is the best solution to charging your phone or battery in the event of losing power.
Looking into how hand-generators actually work, it seems simple enough. Instead of coal or another energy source, the initial energy is provided by our arms. In 1831, Faraday discovered that by spinning a coil of wire around a magnet, one can create a current. This is usually done quickly with steam or gasoline, but if you shrink the equation down to pocket size, your arm becomes the motor is making the current. Simply put: You crank it to spin the coil of wire around a magnet to create the current. The longer or faster you crank it the more energy you can produce. Being in the military myself, I found it interesting to see that hand-crank technologies were first used on the battlefield in the 1960s to charge batteries. Thinking on a much larger scale, wind turbines use the same technology.
I believe that hand-crank generators are an absolute necessity because you never know what can happen in life, and relying solely upon one energy source for power is foolish. When power goes out, we create fire and light candles but lose our phones once their batteries die. This gives a chance for vital communication to still exist with charging your batteries through a hand-crank generator.
