Orange Battery Batterinum citrus
As our access to fossil fuels become more difficult, and our reserved decreases, there is a drive for alternate sources of energy. Frequently cited as possible alternative sources to oil and natural gas are wind, solar, geothermal and nuclear power. But perhaps there are other, less obvious sources? For instance, an orange? Artist Caleb Charland uses fruits and vegetables to power the light for his long-exposure photographs. The light emanating from this orange is the result of the chemical reaction between the citric acid and the zinc in the nails, thus powering a light bulb. Now granted, this particular photograph is the result of a 14 hour exposure, but perhaps in order to solve the looming energy crisis we need to think beyond the obvious solutions.
