Some estimate the average distance a piece of food on any given dinner plate in this country travels 1,500 miles! Look at all the necessary systems to make this possible! Without mechanized farming, high powered processing, and a network of distribution systems, food would become prohibitively expensive.


The distribution infrastructure for food delivery in today's America requires plentiful, low cost, and distributable energy. Much of this energy comes from oil, coal, hydroelectric, and nuclear power plants.


Factories are needed to make the tools for building and maintaining this infrastructure. In addition, warehouses, fork lifts, food delivery trucks of many kinds, supermarkets, parking lots, and all the city infrastructure to support this delivery system must exist. The list of needed machines and tools goes on and on.


Without plentiful cheap energy, this distribution network begins to fall apart as more people find it cost effective to grow their own food. The victory gardens that proliferated during World War II show what can happen when cheap energy becomes unavailable.












Now imagine living close to the great majority of the systems that grow your food. Within walking distance you find complex food growing environments powerfully integrated with waste processing and electricity generation. A great variety of complex architectural designs are mutually supporting to produce many kinds of foods and medicines. These include underground greenhouses, cloche fields, sunken espalier wall gardens, wetlands treatment systems, and low rise through high rise greenhouses.


These greenhouse complexes do far more than grow food. They generate electricity with cogenerating microturbines and other alternative energy systems. Waste heat from power generation may be put to useful work pasteurizing waste (landscape, and/or housing), drying lumber or food, keeping greenhouses warm in winter months, or even keeping outdoor fish ponds from freezing. During the fall harvest season when food is more plentiful, waste heat helps the canneries achieve process temperatures for their hot water needs. These are switchable, cascading, mutually supporting systems. This form of urban agriculture is crucial to the function of linear cities.


Just as modern cities have growers markets, and community gardens, linear cities will have neighborhood scale produce markets. These markets sell their produce ultra fresh because it was picked within walking distance from the market. Food is not picked until it is ripe enough for the market or the cannery. This is a form of demand side economics.


The close fit between market needs and production capability is a powerful principle that helps lower the cost of living in linear cities. Since there is much less waste in the entire process for growing and distributing food (an outcome of less handling by fewer people), the cost for delivering food drops. Less packaging because much more of the food we eat is eaten fresh from the source, means less trash handling capability is needed in the city. Because of proximity power, these kinds of food producing systems can dramatically lower the cost of living while increasing the quality of life through increased variety of consumables.


Urban agriculture systems that are showing up in cities all over the world are proving the technologies that combine to make the rich variety of regional, linear city, greenhouse complexes possible. Yes, support urban agriculture! *****


We may be seeing ever more need for disaster relief for large populations in the future.  Many people have been made suddenly homeless by natural disasters and human caused problems.  Tower Towns can be a way of helping people made homeless have a place to live.
