Mobile Phones Make Us Free – Until They Need Charging
That’s always been the trouble with mobile phones, they have liberated us from the desk and allowed us to wander around the hillsides, country lanes and down the high street, talking or texting to whoever we wish – that is, until the dreaded “blip-blip” warning that emits from the mobile telling us of an imminent power failure and a desperate need to charge up before the fateful screen goes blank.
But those long rambles in the summer sun through pretty countryside with our mobile phones guiding us with maps, camera opportunities and the ability to call someone in an emergency could be back on the menu as a distinct advantage, thanks to the unlikely concept of three Chilean students.
It was the plants which gave the student an idea. She thought if plants had no charging socket, yet still seemed to gain energy from the soil, then why can’t that energy be used to power a mobile phone? Just as you read it, all of a sudden you wish you had the idea.
Plants produce energy through a process called photosynthesis (come on, we all learned that in our biology lessons, didn’t we?) – Therefore, if a device could be planted into the ground and then used to create a charge for your mobile phone. The device in question is the CO2 free greener mobiles charger known as the E-Kaia.
The E-Kaia has two pins which plug directly into the soil and is no bigger than a small device or cell phone and can harness enough energy to charge up a phone for a two-hour period. That is the time period most planet-friendly mobile phones would need to charge right up to 100 percent from dead.
The three Chilean students are already in the process of applying for a patent on the product and we can expect the chargers to be on sale by the end of the year in 2016.
