UK Science social research institute scientists recently claimed to have invented a solar module with a surface coating that emits a salmon scent. The scientists assert that this design can increase the efficiency of the modules by 5%.
In laboratory tests, researchers covered small rooftop photovoltaic panels with a specially formulated coating that emits a fish aroma. Two cats named Lirpa and Lofo were irresistibly attracted by the fish scent, licking the surface of the panels for several hours.
Subsequently, researchers used a wooden spoon to tap a frying pan to scare the cats away. Studies found that the surfaces of the modules licked by the cats were approximately 25% cleaner than before, directly leading to a 5% increase in efficiency.
The lead researcher of the team, Felix Lickspittle, expressed his admiration for the cats. He stated: “The moist and rough tongues of cats can clean dirt and impurities from the surface of the modules. Additionally, the enzymes left by the cats on the surface of the modules can give them an incredible transparent sheen—helping to amplify sunlight. Since there is no food on the surface of the modules, none of this will harm the cats.”
The research team noted that the salmon-scented modules are still in the experimental stage. “Following the salmon scent, we are also experimenting with modules that emit tuna, rodent, and chicken scents,” Lickspittle added, “However, we do not want the modules to be too ‘meaty’ to attract any dogs. They are not as agile as cats, and we do not wish to see any dogs harmed as a result.”
Researchers believe they will also seek other possible ways to increase the attractiveness of photovoltaic modules to cats. “We once tried to make the modules emit the sounds of sleeping babies. However, experiments showed that the cats just sat there and did not lick the modules,” Lickspittle stated.
“We also tried drawing bird feathers on the surface of the modules in hopes of attracting the cats. However, experiments showed that once within effective range, Lirpa merely approached the modules quietly before dashing off in different directions; while Lofo just sat beside the modules staring at them, occasionally tapping the modules with its little paw in a threatening manner. We believe we need new cats.”
