If so and you want to support the creation of a new green source of electricity, today's post about a mini hydroelectric power plant for charging small electronics in nature is intended just for you. Currently, powerbanks and various solar chargers are experiencing a huge boom in development and sales. Solar kits are indeed a functional option for "that kind of travel charging," but there's no point in kidding ourselves - from our own experience, we know that to charge one smartphone, GPS, or LED lamp with solar charging, you need to take a week's vacation. Yes, we're exaggerating a bit, but charging a battery cell often takes ten or more hours.
Against solar charging now stands a water kit called © Blue Freedom
This is a small 7.9 x 2.2-inch water kit that is lightweight and fits in a small backpack. The kit contains a micro turbine 4.7 inches in diameter, a 5W generator, and a 5000 mAh lithium-polymer battery. You simply submerge the turbine in a river while the base unit remains on the shore. It works simply. It's like casting a baited rod into a stream and clipping your phone to the rod for charging. You can then charge your devices directly by connecting to the base unit via USB ports, or let the built-in battery charge and use the stored energy later. The company estimates that a smartphone should fully charge within 2 hours, while the internal battery fully charges in just 3 to 4 hours. All this with a water flow of 1.2 m3/s. (...just for comparison, the Berounka River has an average flow of 36 m³/s) © Blue Freedom Blue Freedom is designed to work at temperatures between 5°C to 40°C and at altitudes up to 4999 m. The device works similarly to HydroBee (water gadget), just significantly smaller. This gadget is currently on Kickstarter (crowdfunding project financing) and is trying to raise enough funds for full-scale factory production. You can contribute $5. If you give $219, you'll get the kit in October this year, with great savings. And if you contribute $10,000, you'll become a distributor of the device. We at Greenhousing are supporting it. And you?
