Cave World Transportation System

In the most cases only goods have to travel because the individuals are connected via an information system like the internet. The caves are connected by tubes which allows to transport electricity, data, and materials. Big machines needs to be produced in each cave system independently because the building of wide tubes are very costly. Transportation of goods and machines through the outside world has a high risk of contamination and requires a lot of decontamination work after the transport. Therefore it is not likely that this will happen very often. It is also more likely that each cave system needs to build up its own ecosystem independently from each other that in case of a contamination of one of the caves the other are still able to survive. Therefore only raw material needs to be transported between two distant cave systems. Recycling will be come an important part of the work which needs to be done. Each cave should have their own recycling facility and are able to recover all goods from the waste. Waste itself should be minimized and if it can not be avoided to produce waste, then this waste should be recycled and design to be recycled. Organic waste will be used in the organic tanks so that a transportation system for organic waste needs to be established. Most of the organic tanks which produce fresh air and food are close to the living areas of the people. Therefore only excess sludge needs to be transported to distant places. These excess sludge can be put into containers and like other goods transported via the transportation tubes. These tubes are just wide enough to transport containers with people to allow an exchange of people between the cave systems. And this will also determine the size of the containers.
