Short Bytes: There’s a bell in the Clarendon Laboratory at Oxford University that has been ringing since 1840. The researchers don’t know the exact composition of the cell that’s powering the bell. They are also afraid that opening the bell might ruin the setup. Its power source holds the Guinness World Record for the “world’s most durable battery.”In the Clarendon Laboratory at Oxford University, there’s a bell that has left all the researchers and experts awestruck. This bell has been ringing nonstop since 1840.
According to the university, the bell’s clapper oscillates back and forth, making it ring. Since its inception, it has rung roughly 10 billion times. Wondering about the power source of this bell? Well, it’s powered by a single battery that was installed in 1840.
Dry pile is one of the first electric batteries and uses alternating discs of silver, sulfur, zinc, and other materials. The researchers haven’t been able to find out the exact composition of the cell, but they know that the outer sulfur coating seals the electrolyte. They are afraid that opening the bell to know more about the cell will ruin the bell experiment.
Oxford University also suggests that it may have actually been set up as early as 1825. The bell’s power source also holds the Guinness World Records for the “world’s most durable battery.”
After more than 175 years, the voltage left in the battery is so low that human ear can’t actually hear it ringing. In each oscillation, the bell uses 1 nanoAmp current.
