Check Out This Portable Generator Powered By Water
This cool little invention is called the Estream and it’s purpose it to generate power for your USB connected devices while you’re enjoying the outdoors.
It works by turning moving water into stored energy. By letting the device float in running water, the turbine on top spins charging the battery.
You can even attach the device to the back of a small boat or kayak to generate energy if there isn’t any running water nearby.
When fully charged, the Estream is able to charge up to 3 smartphones, tablet PCs, or GoPros. It even charges the devices faster than a standard outlet would.
