uTree: Realistic Mass Solar Energy Generation

Solar energy used to lit up streets of an industrial city is closer than you might imagine. The uTree concept by Xabier Perez de Arenaza is one of the most realistic concepts of solar energy generation. These âtreesâ are of modular structure and can be installed anywhere where thereâre few inches of floor space available to support a pole. A rotation engine is mounted in to ensure âsolar leavesâ of the trees are facing the sun. There are 77 solar cells per leaf each generating 2.5w energy per day, meaning a medium tree can generate 13.86 KWh per day.
