Forget messing around with hydrogen cells and whatever ‘futuristic’ dribble they are buzzing about these days, Popular Mechanics magazine (popularmechanics.com) from March 2004 has a small article about a water battery.
Battery taps water
"A radically new type of battery takes advantage of the way water molecules line up when they come in contact with glass. The electrokinetic micro-channel battery developed by Larry Kostiuk and his colleagues at the University of Alberta makes use of the fact that water molecules have positive and negative ends. Glass takes on a positive charge whenever it touches water, explains Kotiuk. Conversely, the negative-charged ends of all the water molecules line up facing the glass container. In the battery, water flows through glass channels, producing electricity along the channel walls. ’Each channel contributes less than a nanoamp,’ says Kostiuk. ‘But you can gang together as many as you need.’ The prototype shown here cranks out 2 microamps."
There is nothing in the photo to compare the size of the water battery to, but it appears to be about the size of a 2 or 3 liter bottle. Now let us imagine the applications of such a power source…
