Logistics, vehicles and transport routes in the near future
Hitherto unimaginably large cities with 150 million inhabitants are in planning. How can so many people be accommodated in a small space? How can they be procured with food? How can they communicate with each other personally? How can their waste be disposed of? How can they be supplied with fresh air? How can they live without undue stress on nature? e.g. through very high energy consumption?
Many questions can be answered: by new concepts for logistics. Goods, people, information, energy must be transported; and to a sufficient extent, promptly and punctually and above all reliably. Logistics requires vehicles / cars and / or transport routes. Transport routes are hardly available. Therefore, new demands are made on the traffic systems. Traffic will be multi-dimensional. Monorail systems, tunnel systems become necessary and, above all, completely new vehicles for private transport.
In the future, different vehicles will be developed for urban and interurban traffic. Transport routes, traffic systems, the mode of driving as well as the requirements of cars will diverge.
In overland traffic, there will be driverless cars that can transport people and goods with minimal fuel consumption. Because of its high energy density, the diesel fuel will not be so easy to displace from the overland traffic. Possibilities will be found to minimize its harmful effects as far as possible; e.g. the admixture of urea to the exhaust gas or the synthetic modification of the molecules by adding oxygen. Whether the diesel fuel or another fuel with high energy density is then fed into an internal combustion engine or an H2 reformer before a fuel cell, is still open. A fuel cell for driving electric motors should have a slightly greater overall efficiency. The fact that batteries made of thousands of small round cells or the like - known from laptops - prevail as energy storage, sounds unimaginative.

In city traffic, cars are needed with the lowest possible exhaust emissions, low fuel consumption and a particularly small footprint, both parking space and free space to drive. The city cars must therefore be steered by a driver who can quickly pick up and react to the driving situation and can fit his car precisely in the smallest gaps in traffic. The city car will be powered by electric motors free of pollutants. The electricity is largely produced outside the city. The city-car will have to cover about 80 km on one way and does not have to drive faster than 50 km / h. It works with a small weight-saving battery. The vehicle is recharged at a power column or via an on-board photovoltaic on the outside of the body.
A city car is built tall to allow as much transport volume as possible and also surface for the photovoltaic. It has to be light; i.e. under 100 kg empty weight incl. battery, so that the energy consumption is minimal. Such city-cars can be made from - in the future perhaps compostable - fiber composites.
The height of the city car increases the risk of tipping on bends or on sloping roads. To limit this high risk, good technical solutions still have to be found.
