Using fractal nanostructures to build e.g. car can make transport far more efficient than with regular techniques.
When transporting goods or people, the largest part of the energy is used to move the weight of the vessel itself. The average car weighs 1200kg. Most of the times only one passenger is moved – so to transport 80kg of human we need fuel to transport 1280kg.
Fractal nanostructures could shift that imbalance drastically.
