The gray parts of this model show how much of Arcosanti exists today
Though Arcosanti isn't as colossal as planned (at least not yet) it's still interesting. The mixture of public and private spaces, living, working and entertainment spaces works well—for people like me, anyway. Most of the complex uses passive climate control. Sun for heat in winter, shade and thermal mass for pleasant temperatures in desert heat. There are water features, olive trees, grape vines, succulents and ornamental plantings that are also functional.
It would be great if benefactors were to dump a pile of money into Arcosanti so the work could progress further and faster. It would be even better if enough people were interested in alternatives to suburban sprawl so that developers would create places employing the principles of Arcosanti.
