Science Behind the Evap-o-watt

Green power sources are in high demand these days. There are many sources to harvest such as solar, wind, vibration, hydroelectric, waste heat, RF rectification etc. At FunSci Technologies, we have developed a new method of power generation called the Evap-o-watt, which is based on the evaporation process. We believe through art and science, power generation can be demonstrated in a fun, truly natural, truly renewable, non-carbon based way - with water!

Electric Power Directly From Water

Evap-o-watt is a new technology for generating small amounts of electricity without moving parts or an electrochemical cell. Evap-o-watt can produce 0.7 Watt-hrs for up to a week, continuously, with one fill-up of distilled water!

How does it work?

The Evap-o-watt is a device that uses the evaporation of water to create electrical power. When water evaporates, it uses heat energy to transform into vapor, reducing the temperature of the surface it evaporates from. This is the principal behind a Hygrometer which measures Relative Humidity. An Evap-o-watt exploits the difference between this reduced temperature and room temperature using a Thermo-Electric Generator and an Energy Harvesting circuit to transform the heat energy of the water evaporation process into electrical power. LED sculptures or other devices are used to demonstrate that power being generated.

Renewable Energy

The Evap-o-watt is a device power by evaporation of water that can be a Flashing LED Display or other device. It is a truly renewable energy source, lasting virtually forever as long as you keep water in its bowl and the Relative Humidity level at its location is below 70%. The Evap-o-watt is 100% green and renewable, doesn't require a battery or wall socket to operate, and there is nothing to wear out!

A single Evap-o-watt can produce 0.7 Watt-hrs for up to a week with a fill-up of distilled water. The power is used to flash multi-colored LEDs to add sparkle to some fun sculptures or to power an appliance such as an LCD Clock. Every other water powered device on the market up to now has used the "Dissimilar Metals" electro-chemical cell method which is not truly renewable. Their parts must be replaced after use or in some cases the device has no user replaceable parts. Their devices are useless after a while and must be thrown out, adding to landfills everywhere. Evap-o-watts operate using evaporation and there is no consumption of parts and therefore will last virtually forever.

Choose From 7 Distinct Designs or Create Your Own!

Currently, the Evap-o-watt is available in seven distinct designs, including the Christmas tree, Menorah, Heart, Cactus, Tarantula, Clock and Starburst. Alternatively, you can choose an Evap-o-Watt kit or individual parts and create your own fantastic design!
