Like other plants, the Biome car can be fueled by the sun's light or solar energy. The idea is that the Biome car will collect this energy and bond the collected energy with a fuel alternative and emitting pure oxygen as a side effect named BioNectar4534 (BN4534). BN4534 is a liquid chemical bond that is stored in the BioFibre. Also, Mercedes-Benz says it's developed a technology to equip trees with certain receiver that can collect extra solar energy and turn it into BioNectar4534. BioNectar4534 also isn't existent currently so this is all of the information available.
