Mystery of Oxford's ringing electric bell and its unending battery
The Electric Bell from Oxford has been operating continuously for 184 years, since 1840. The secret to its longevity lies in its unique battery.

The Oxford Electric Bell, located in the Clarendon Laboratory at the University of Oxford, has been ringing non-stop for over 184 years. It is one of the longest-running scientific experiments in the world. This mechanism, known as the Oxford Electric Bell, emits delicate sounds that have amazed scientists for years due to its incredible durability. As reported by IFLScience, the bell's mysterious long-term operation is powered by an extraordinary battery, the working principle of which remains unexplained.
The mystery of the extraordinary battery remains unresolved
Professor Robert Walker purchased the bell from the University of Oxford. It is powered by two brass bells - a prototype of an early battery. The battery has not stopped powering the mechanism since 1840. Although the exact composition of the battery is a mystery, it is believed to be covered with sulfur, giving it a candle-like appearance.
Scientists have theories about the battery's operation, but they cannot access its interior to confirm them. In an interview with the BBC, Dr Robert Taylor points out the bell's extremely low energy consumption, which, combined with minimal energy losses due to air resistance, may explain its longevity.
Will the Oxford Electric Bell stop ringing soon?
Despite its incredible durability, the bell might soon stop functioning. This conclusion is based on observations indicating that the ringing rate has significantly slowed in the last four decades. According to Taylor, the battery might last another 5-10 years. Every battery eventually runs out, and this would mark the end of this fascinating experiment that has intrigued scientists for years and left many questions unanswered.
Will long-lasting batteries appear soon?
Chinese company Betavolt Technology has developed a prototype miniature atomic battery that has the potential to revolutionize the powering of electronic devices. Betavolt Technology focuses on a betavoltaic battery, which uses a diamond semiconductor and a nickel isotope. This innovative battery can operate in extreme temperatures and theoretically not discharge for 50 years.
The BV100 battery prototype is currently under development, but Betavolt Technology plans to introduce 1 W batteries to the market by 2025. Their idea is that users can connect them, powering modern devices without charging. This could completely change how we use mobile and utility technologies.
