浪花直播 and Professor Saiful Islam have set a new GUINNESS WORLD RECORDS鈩� title for the highest voltage from a fruit battery.

We used 2,923 lemons to generate an astonishing 2,307.8 volts, which smashed the previous world record of 1,521 volts, and launched a battery-powered go-kart race run by the . The electrifying feat was designed to highlight the importance of energy storage and the need for new innovations for a zero-carbon world against the backdrop of the COP26 Climate Change Summit.

鈥淚t was very exciting to regain our Guinness World Records title by squeezing the highest voltage from a fruit battery. It鈥檚 an amazing feat, but it鈥檚 still not an effective battery 鈥� the amount of electrical power would not be enough to turn on a smart television.

鈥淏atteries have a vital role to play in reducing carbon emissions 鈥� and have come a long way with modern lithium batteries helping to power the revolution in portable electronics and mobile phones.

鈥淚f we are serious about reaching net zero carbon status we need better batteries 鈥� to power more electric vehicles and to store the energy from renewable sources such as wind and solar.

"It鈥檚 an exciting time to be a scientist in general and a chemical scientist in particular 鈥� as scientific research is crucial to understand how batteries work and to discover new materials that will give us technologies that can store more energy, are safer and recharge faster.

鈥淲e also have to be able to recycle and reuse these batteries effectively to enable a truly sustainable energy future.鈥�

After all that zest

Following the record attempt, the used lemons were responsibly processed by , who generate renewable energy from food waste using the (similar to an industrial-scale compost heap) to produce biogas. After further refinement the biogas is pumped directly into the National Gas Grid. Any remaining liquid is transformed into bio-fertiliser for local farming and agricultural use.
