In many areas of the world, and also during times of natural disasters, clean drinking water and access to power are scarce. The company The Essential Element has designed the Hydra water purifier and fuel cell to take care of both of those problems at once.
The Hydra is equipped with a 2.88 kW solar panel array that runs a pump that pushes water through a self-cleaning filtration device (capable of purifying 87,000 liters a day), juices up lead-acid gel batteries and runs an electrolyzer that splits some of that water to fill a .37 cubic-meter tank with pressurized hydrogen.
The fuel cell can be used to power communication devices or a camp stove. The whole device can easily be set up and collapsed for easy transport and includes PV mats that can be plugged into the device for extra power.
