While rechargeable batteries for smartphones that use solar energy help us to be able to charge those devices in a fairly simple way, always a new idea appears which could be the one that takes the cat to the water to generate electricity if the necessary conditions are met.
Estream is a Electric generator that uses the hydraulic energy of any stream of water to charge the mobile device in a very ingenious way. A generator that can be easily carried in the backpack and that by the time we make those trips to the field for a few days, it can become a basic tool to always have the smartphone charged.
Estream stands out for convert any stream of water in stored energy, charging any type of USB device, perfectly wearable in any type of backpack and has a modular design to expand it for any type of application.
Like a generator produces 2.5W- 5W of power. Being suspended in the water, the stream of water makes the turbine rotate. The rotation activates the generator to generate electricity. Estream even works if the current is weak or you are following a boat or kayak.
In total they are 4,5 operating hours to charge a 6.400 mAh battery, which is not bad by the way and is capable of charging up to 3 smartphones, a GoPro and even a tablet PC. Being rechargeable, as long as you have access to a stream of water, you can continue to charge the devices.
One of its greatest qualities is modular design, so it can be used to keep a device charged while in the water. The opportunities it provides are quite striking.
A very interesting idea that is now on Kickstarter and already has earned $ 122.245 of the $ 80.000 goal. We hope it is a success and we see its commercialization.
