Why aren't ceramic motors built?

While traveling from Finland to Chile, Prof.-Ing. Julius Natterer, Lausanne, the world expert in wood construction at all, at the NRW Wood and Forest Days 2001 in Nettersheim.

Nettersheim - "I once moderated a symposium with Natterer in the Ruhr area, where we had to send 300 people back home because the hall was too small," reported Forest Director Henning Walter. Understandable, because Professor Natterer is the “wood construction philosopher” in general. He has even become the house and farm planner of several Scandinavian ministries by provoking the Finnish government with the sentence that an underdeveloped country can be recognized by the fact that it exports its most valuable raw materials for little money and imports gravel and cement, oil and steel in return .

Prof. Julius Natterer, the son of a Straubing forester, familiar with wood from childhood on, designed several buildings at Expo 2000, including the wooden world church, built large communal halls and ice rink stadiums in the alpine region, and architecturally daring domes, bridges and on all over the world Tent roofs suspended from towers were designed and implemented. Everything made of wood.

Natterer uses solid wood and developed the board stack construction, he uses lightweight concrete made of cement and wood chips. He helped develop a method of how to weld wood, and he claims: “One day in the not too distant future we will be building cars out of wood. The best aerobatic planes and spy jets invisible to radar screens are already made of wood and fly with ceramic motors. "

Henning Walter, the aforementioned head of the Schleiden State Forestry Office in Gemünd, was bitterly disappointed about the weak response Natterer's appearance on Saturday at the NRW Wood and Forest Days 2001 in Nettersheim had. Well below 100 listeners listened to the revolutionary sounding yet well-founded theses of the wood professor: “I don't know of a single 150-year-old concrete ceiling from which I could deduce anything about the durability of this building material. But I can show you a completely intact triple wooden ceiling from 1140 in St. Stephen's Cathedral in Vienna on the fifth floor. "

Mayor Hermann-Josef Mießeler was also enthusiastic about Natterer's presentation, but at a loss in view of the weak response: “We personally invited 1200 architects and engineers in the Euskirchen district and in the neighboring districts. Likewise the most important decision-makers of the municipalities and regional authorities ”. In the end, fewer than a hundred listeners came, only a few designers and planners among them, according to Mießeler, and almost no decision-makers from the public sector who could represent a construction philosophy other than that of the unconditional primacy of concrete.

In addition to Julius Natterer, who has held the first European chair for timber construction at the Federal Technical University of Lausanne for 22 years, Henning Walter and architecture professor Ulf Hestermann from the Erfurt University of Applied Sciences were speakers at the Saturday symposium in Nettersheim.
