The goal of the Land Art Generator Initiative (LAGI) is to design and construct Land Art / Environmental Art installations in the United Arab Emirates that have the added benefit of large scale clean energy generation. Each sculpture will continuously distribute clean energy into the electrical grid with each land art sculpture having the potential to provide power to up to 50,000 homes in the UAE.
