By means of super-light structures, engineers can place compressive forces in optimal paths and the strong material is used to the fullest extent. The remaining part of the structure is filled with a cheap light material. This is the reason why super-light structures can be made much cheaper than traditional structures, where the strong and relatively expensive materials are not confined to a minimum.

If the overall design is made so that tensile forces can be avoided, price reductions of a factor 10 may often be within range.

A number of design cases have been made to document these statements.
