Evapowatt LED Displays

Complete, decorative LED display assemblies as a conversation piece, artwork, or demonstrator of how natural processes can be harnessed to create art or display scientific principles in action. Powered only by water, these displays can be used anywhere that conditions are favorable (Room temperature, nominal RH) and require neither batteries nor wall sockets to light up. Other technologies have used water as an electrolyte of a battery comprised of dissimilar metals. Evapowatts are not batteries and thus will not be consumed over time. Yes, you read that right, they have a truly renewable energy source and will last virtually forever as long as you keep them watered. Four cups of water (distilled is highly recommended) will last roughly 1 week, give or take a day or 2 depending on the atmospheric conditions where it is located.
