We are the most technologically savvy age until the battery runs out, and then we simply have really expensive paperweights. Today’s society is more on the go than ever before. We lead busy lives. Technology has adapted and evolved to allow us to do so. With the advent of mobile phones, tablets, and laptops, we are able to free ourselves from the nine to five office cubicles. We can take our work virtually anywhere with us. You can’t walk more than a couple yards in a busy city without seeing somebody check the market on their phone, video chat a boss with a tablet, or finish a deal on a laptop. More and more public places are offering free Wi-Fi, which allows us to continue our work anywhere. However, there is one major flaw in our highly evolved technology: it needs a battery to work… we are completely at the mercy of the battery.
Battery’s New Best Friend
As of recently, there is a remedy for the frailty of batteries. Scientist have merged the rather new technology of solar power to the age old faithful backpack. All that the backpack requires is time and sunlight, and it will enable you to never run out of juice again, unless of course you prefer a record-breaking extension cord. The backpack sounds a bit complicated but is actually pretty simple in theory. It uses photovoltaic (PV) cells to produce energy. The cells are grouped together in columns or panels designed to trap the sun’s light. Once the light has been trapped it uses a semiconductor—the devices that conduct electricity, to power the pack.
The Secret to His Friend’s Success
As sunlight hits the pack the semiconductor absorbs the light and energy from the light. Once the light is captured the columns then manipulate the light and harness it using PV cells to force them to flow in the same general direction. This flow creates kinetic energy, which is then used to make electricity. Once the electricity is produced it can be either tapped into immediately or stored like a battery. However, the semiconductor is naturally shiny and doesn’t absorb sunlight very well, which some consider a fair trade in light of our inherent attraction to shiny things. To counter this, designers coated the semiconductor with an antireflective light, which allows it to capture a maximum amount of light.
This Buddy Brought Back-up
All of this sounds pretty intense but when it is broken down the backpack is lightweight, and waterproof. It is still stylish and doesn’t appear to be cumbersome or tacky. The pack is able to produce up to four watts of power, which means you could power your phone for ninety minutes after just one hour of sunlight. However, what really sells the backpack is that it has a lithium-ion battery on the inside of it, which is able to store energy. This is crucial because after just ten hours of sunlight the pack can produce fifty-five hours of stored energy. This would mean that even in cloudy days you would have enough juice to get you through at least two days. Also, if you didn’t have time to stay out in the sun or it was raining all week, there is hope. Good ol’ fashion power inverter technology e.g. a kisae inverter, etc., kicks in and the pack’s AC adaptor allows you to charge the pack with your car.
