The problem of recharging mobile devices and providing emergency lighting is solved using a portable HydraCell Power Cube, which instantly generates electricity when salt water is added inside the case (concentration 7.5%).
Electricity is generated by contact of the electrolyte with interchangeable plates mounted inside the HydraCell housing. After “refueling” with saltwater, the device can operate for about 250 hours.
HydraCell’s power is small, but it is enough for the primary provision of small mobile communication devices in case of an emergency power outage or in an area where there is no centralized power supply.
The developers note an almost instantaneous supply of energy after adding an aqueous saline solution as the main advantage of HydraCell Power Cube. The power of this compact device is enough to charge from 5 to 10 smartphones on one set of stationary plates.
One set of interchangeable plates is enough to provide from 50 to 100 hours of lighting using LED lighting devices of various capacities. The HydraCell device will provide lighting in case of an accident, on the road, or while camping.
All waste generated after using HydraCell can be disposed of safely, as it quickly decomposes and does not harm the environment. HydraCell housing is made of recycled plastic.
Fundraising for the HydraCell Power Cube project is going on at the Kickstarter crowdfunding site. A few days before the end of the investment period, three times more funds had been raised than was necessary to launch the project. HydraCell Power Cube batteries will be shipped to their first customers in August 2020. You can pre-order them at the price of $54.
