Can thousands of lemons power a high-performance electric supercar?
When faced with the challenge of charging a Volkswagen electric supercar for the Pike's Peak race, engineer Mark Rober turned to an unlikely source of energy. By combining citrus with large-scale experimentation, creators are exploring the boundaries of fruit-based voltage and the future of energy storage.
The pursuit of high-voltage fruit batteries has recently reached a new peak. In a massive demonstration of scale, a team led by the Royal Society of Calcium, featuring University of Bath expert Professor Saiful Islam and science presenter Fran Scott, successfully set a Guinness World Record. By utilizing a massive array of 2,923 lemons, the researchers managed to produce a staggering 2,307.8 volts. This feat significantly surpassed the previous record of 1,521 volts and was used to power a go-kart race organized by the Blair Project in Manchester.
While such large-scale citrus batteries serve as powerful scientific demonstrations, they also highlight the broader, more serious challenges of the modern era. The Royal Society of Chemistry designed this record-breaking attempt to draw attention to the necessity of innovation in energy storage and the transition to a zero-carbon economy, particularly during the period surrounding the COP26 Climate Change Summit. The project underscores the vital role that new technologies play in tackling global climate issues.
Beyond the spectacle of the battery itself, research conducted by the RSC reveals a deep engagement with sustainability among the younger generation. Surveys indicate that 75% of young people feel anxiety regarding the planet's future, while 78% believe the responsibility for addressing climate change must be shared. Interestingly, while 81% of youth believe schools should teach about sustainability, only 38% see a clear connection between studying chemistry and pursuing a career in the sustainability sector. This gap highlights a significant opportunity for educational reform and the promotion of scientific careers in the green economy.
