Sometimes mobile electronic devices are not only useful, but indispensable. Whether you want to spend some time off grid (maybe camping) or if you run out of power, in an emergency being able to make a request for help makes the difference.
If you need energy always and in any case, now you can count on HydraCell Power Cube, a "battery" that works by simply adding sea water (or water and salt) to this portable generator. launched on Kickstarter.
HydraCell Cube is like a lithium-ion power bank, but with the convenience of generating energy without having to plug it into an electrical outlet and wait hours. It is sufficient, as mentioned, to pour salt water into the top of the cube and obtain immediately energia.
HydraCell Power Cube, energy from water
Since HydraCell is a water activated fuel cell and not a battery, it can stay on a shelf or in the car for more than 25 years and still be ready to recharge devices in an instant.
A normal conventional lithium-ion battery slowly loses its charge over the course of about three years, while alkaline batteries find their “expiration date” in about 10 years.
Friend of the environment
Exhausted batteries often end up in landfills where they can spill toxic chemicals harmful to the environment into the ground. The HydraCell water and salt "battery" does not present this danger: its main body and the upper panel are made of recyclable ABS plastic and rubber, or (as an option) completely biodegradable.
HydraCell generates electricity by activating a chemical reaction between magnesium and oxygen. This triggers the release of electrons that travel back to the carbon cathode collector and generate electricity which can then be spread via a USB port.
The magnesium charging plates can be easily replaced when they are discharged, with each set capable of supplying energy or up to 100 hours of light using an included accessory.
With its dimensions of 6,7 x 4 x 1,4 cm and a weight of just 28 grams, HydraCell Power Cube is perfect for emergency kits or when camping.
