About two years ago, Seoul-based company Enomad made news when it put mobile phone charging stations along the manmade Cheonggyecheon River that runs through the Korean capital’s downtown. The stations used the force of the river to turn turbines and generate electricity. This year at Austin’s SXSW festival, the company has demonstrated that it’s been able to shrink the concept down to fit easily in anyone’s hand – or backpack.
Also called Enomad, the bullet-shaped device is about the size of a thermos. Remove the white translucent cover and you reveal four propellers that flip down and lock into position. Once the device is assembled, you can simply place it into any flowing water source to charge it up. Alternatively, it can be towed behind a kayak or any other water vessel. The idea is to get the propellers spinning to turn an internal turbine that charges up the onboard 5,200 mAh battery.
