< Water product concept >
Combining creativity, interest, environmental protection and experience science is the biggest feature of water-driven products. You can fill your hands with water.
Make the product generate kinetic energy; you can observe the flow of water in the transparent housing and increase the fun; you use the water-driven production.
At the same time, it is also saving several traditional batteries for the earth and participating in environmental protection actions!
< Notice >
Inject 10 ml (cc) water
No water change
Two (2) years life
4. No battery, No poison
< Philosophy of Water-Driven System >
The water power(environmental) calculator of water-driven system is on innovation, fun, environmental, and science experience.
You can input liquid (H2O) into the system to generate stable voltage.
There is a transparent window to view the water flowing when using water-driven calculator.
And these green material are much more environmental compared to traditional batteries when they are discarded.
< Water-driven(Environmental) calculator Introduction >
Solar calculator is known; but water-driven calculator is so cool and special.
The different point with other is used via water to generate power without battery.
The water-driven system is not very difficult but it is quite new to us.
This water-driven calculator is combine machine (mechanical) and technology.
The water-driven calculator will be ON upon input water.
The water seems nothing changing after using a period of time.
Do you want to know why? There is a magic engine internal to convert chemical energy to electric.
There are three color for water power calculator~
Different angle ~ Put into water to make calculator ON (No battery inside)
Side view ~ light & safe ~ no leakage
