Let’s say that you’re planning on going camping or hiking and want to bring your gadgets with you, but in nature there are no power outlets for you to plug your devices into for charging, instead you will have to rely on battery packs or even solar-powered chargers. However while the latter might be a good idea for the outdoors, what happens when there isn’t enough sunlight to charge it?
This is where the Blue Freedom mini hydropower plant comes into play. The device, as the name suggests, uses water to help generate energy which can then be used to charge your mobile devices. Given that it uses water, you should be able to use it just about anytime of the day as long as you have access to a water source. Basically the turbine needs to be immersed in a running water source and it should generate enough energy to charge your smartphone within 2-3 hours.
