Traffic flows smoothly
No congestion or traffic delays – even though the transport volume has more than doubled since 2010. The reason for this is techniques whose basic mechanisms were already known in 2015, but which could only be realised later by the joint efforts of several disciplines. Completely new lightweight materials have been developed to build lighter, highly fuel-efficient cars, for example. Self-driving cars must not be as crash-resistant as their predecessors and can therefore be made from lighter materials. Autonomous driving requires smaller distances between the cars, which frees road capacity. The continuous monitoring of material parameters was another step towards more safety and reduced material demand. Since fuels are almost completely made from renewable resources – without competing with food crops – there are no major obstacles to satisfying the steadily growing demand for mobility.
Premises for 2050
- Transport volume has doubled since 2010 – from nearly 40 to 75- 80 trillion passenger kilometres per year.
- Vehicles are largely made from recyclable materials; communicating vehicles and autonomous driving systems provide adequate road safety and require significantly less material.
- Principles of lightweight construction enable energy savings and reduce the consumption of fuels and materials.
- Intelligent monitoring of material parameters is used to record the loading history of components and inform about service life and necessary replacements before defects occur.
- Competition between biofuel and food production has been abolished by politics and legislation.
Ideas directly related to paper until 2030
- Deep-drawing quality: moulded parts typically used in vehicle construction can now also be made from paper materials to produce recyclable lightweight structures; key step towards lightweight construction; also used for seating furniture.
- Car bodies: deep-drawn parts and lightweight, recyclable paper composites based on renewable raw materials have led to weight and fuel savings in vehicle construction; interior trims and skin are made of paper-based fibrous materials.
- Aeroplanes: fire-resistant board for interior trims satisfies all demands but is much lighter and less heat conducting, i.e. not as cold to the touch as earlier materials - manufacturers and airlines are thrilled.
- Small missiles: ultralight drones made from fibre-based, recyclable materials are finally available; technological breakthrough through lightweight construction; drastically reduced energy demand (compared to heavier objects), less dangerous; also used as environment-friendly, lightweight toys.
- Road safety: safer traffic, fewer accidents and injuries thanks to vehicle components made from “self-healing“ paper fibres; car body shells can absorb much more impact energy than in the past; regenerative materials rapidly “heal” damaged components
Ideas indirectly related to paper
- Aircraft construction: bionic structures adapted from nature, e.g. for wings, can be shaped more easily and are much lighter than in the past; innovative design and construction techniques (like 3D printing) are used to make heavier loaded portions more solid and low-loaded portions thinner – like in trees.
- Autonomous driving: has become part of everyday life thanks to high-speed and ever more powerful Internet connections; conventional road vehicles were upgraded, new models look completely different – they are much lighter, compact and need significantly less fuel because crumple zones and stiff (heavy) body parts are no longer necessary; traffic jams are no longer an issue; increased road capacity because communicating vehicles require safety distances of maximally one metre even at high speed
- Soil proofing: car wash sites are no longer profitable because dirt-repellent surfaces make vehicles look as good as new.
