Blue Freedom Hydropower Generator
Using solar panels is an ultra convenient method for keeping your power hungry devices fuelled when you’re off the grid, but if there’s flowing water in the vicinity there’s a new option: the Blue Freedom Hydropower Generator. This small power plant weighs less than a pound and features a hydrodynamic turbine that attaches to a 70-inch long rope-like drive shaft. Secure the donut-shaped device around a stick jammed in the ground, drop the turbine in water — even shallow — and Blue Freedom’s 5W generator will fully top off the built-in 5,000mAh battery within a couple of hours. Then, it’ll charge any and all of your USB-compatible devices at up to 2A speeds.
