For the one in every eight souls around the world lacking access to pure drinking water, how about this: A solar-powered water purification system that spits out pure water, hydrogen and, just for kicks, electricity too. Could it get any better than that?

The device is called Hydra, and like its many-headed mythological namesake it truly serves a multitude of purposes: As its press release notes, “imagine a single trailer-mounted device that turns scum into over 20,000 gallons of pure water a day, stores electricity better than a battery, makes medical-grade oxygen, and runs on the sun.” That’s quite enough benefits from one device, thankyouverymuch.

It works on a very simple, long-understood principle: electrolysis. This is a chemical process by which water molecules are split or decomposed into their component parts, which is two atoms of hydrogen and one of oxygen for each molecule–the magic happens when you apply high voltages to electrodes suspended in water, with gas collection systems at the top of each electrode (one for each gas). In Hydra, the electricity is provided by a giant solar cell, and the gasses are stored in tanks. The next step of the complex system takes the hydrogen and uses it to drive a fuel cell (meaning the system works even when the sun isn’t shining). This generates electricity, which can be used locally and also drives a water purification system.

The products are exactly what you may expect: Oxygen to help with medical problems, electricity for any number of purposes, and pure water at a phenomenal rate. The version shown in the video is just the first working prototype, but when it’s productized and put on sale for $100,000, the device will be designed to be resilient and portable, with the notion that it can be deployed to difficult locations, and even be airdropped into disaster zones to aid survivors.
