The Beginning
After many years of my career as an Electrical Engineer, I wanted to create my own product to demonstrate principals of science in a fun, striking way to spark (pun intended) people's interest in science. Always fascinated by clean energy and energy harvesting, I stumbled upon this technique while looking to power another device continuously overnight. The sub-unit has now become a product in its own right.
The Product Philosophy
To demonstrate what it can do, I thought it might be nice to make a sculpture with blinking lights to catch the eye and foster curiosity about how it works with no batteries, AC plugs, moving parts, or electro-chemical cells of any kind. Just fill the bowl with water (distilled recommended) and watch the lights flash continuously for up to a week under nominal conditions. Refill the bowl with water when it gets low and Evap-o-watt will provide years of fun and entertainment, as there are no components consumed or worn out in the process.
