Gardens and buildings usually compete for space, but by sharing space in a greenhouse, they add to each other synergetically. Yet because this design covers only every other street, it allows plenty of open space for auto roads, parking lots, private yards, and recreation areas. Let's look in more detail at how solar streets might serve their residents. One of our most basic needs is food. Many varieties of tropical fruit and nut trees can be grown under solar street roofs.
Tropical trees can be significant sources of vitamins, proteins, and pure delight to the residents.
The dollar value of a street's produce could equal or surpass that of a non-hydroponic greenhouse of the same area. Shelter and warmth are also essentials. It can work by reducing a building's need for thermal insulation on that side, capturing solar heat in winter, and holding sun-screens to keep the buildings and street cool in summer. A greenhouse roof which spans between buildings can help heating and cooling as cost-effectively as solar greenhouses attached to individual homes do. Two answers are community social space and low-cost transit, both of which are vital to community spirit and function.
