Bedol water powered alarm clock
The Squirt Water Clock keeps perfect time without requiring batteries or electricity. The amazing Bedol Water Clock technology converts ions in the water into clean energy power. This digital alarm clock has a built-in memory chip that remembers time so you don’t have to reset it when you change the water. Water won’t need to be replaced for 6 months or more and it’s simple and fun to do.
Squirt water clocks resemble a small splash of water. Perfect size for a college student’s desk. Just pop open the cap and fill Squirt with ordinary tap water!
- Daily or hourly alarm
- 12 hour or 24 hour clock
- Measures 3 ½” tall x 4 ½” diameter
Bedol brings creative ideas for your home or office in the form of unique and innovatively designed products. Reduce your carbon footprint by keeping time with tap water. Time powered by water, join Bedol in another leap forward towards a greener planet.
How Does it Work?
The secret to the clock not needing a battery is that the water clock itself is a battery. Inside the clock there is an electrolytic cell - or at least most of one. An electrolytic cell is a device that contains two electrodes in contact with an electrolyte. This creates a chemical reaction. The electrodes are made of metal or carbon, and when connected to direct current, one electrode becomes positively charged, and the other becomes negatively charged. This initiates the movement of ions in the electrolyte toward the electrodes: positive ions move toward the negative electrode and negative ions move toward the positive electrode.
Inside the Bedol Water Clock are two metal posts, one is copper and one is zinc. These are well known metals for do-it-yourself batteries, and actually give a good amount of electricity. An electrolytic cell needs two dissimilar metals (the copper and zinc posts), an electric load connected by cable to complete the circuit (the clock circuitry), and an electrolyte to work.
An electrolyte is simply a liquid in which the metals are suspended which conducts electricity. This allows ions that are produced in the electrolytic cell to move freely, letting the magic of chemistry occur. Adding the water completes the electrolytic cell, allowing current to flow and power the clock.
