Caleb Charland a transformat fructele în adevărate celule electrochimice, pe care le aranjează artistic şi le fotografiază, folosind un timp îndelungat de expunere.
Prin acest proiect, el vrea să arate potenţialul energiei alternative, care este cea mai simplă soluţie pentru a proteja planeta şi a asigura totodată oamenilor energia de care au nevoie.
Lumina obţinută este suficientă pentru a realiza pozele, care sunt făcute într-o încăpere întunecată.
Experimentul este simplu şi inspirat din cele făcute de elevi la şcoală, cu cartofi, la orele de fizică. Un cui galvanizat este introdus într-o parte a fructului, iar pe partea cealaltaă este introdusă o sârmă de cupru, generându-se astfel un curent electric destul de slab.
Caled foloseşte diferite fructe pentru acest proiect: portocale, lime sau mere.
