Notre Dame rebuild proposal would bring solar glass, urban farm to cathedral roof

The "green" proposal would bring a 21st-century update to the 850-year-old cathedral.

  • Shortly after a fire destroyed Notre Dame's roof and spire in April, France announced it'd be accepting rebuild proposals from architects around the world.
  • One Paris firm has proposed a "green" design that would rebuild the Gothic cathedral's roof with a mixture of glass, oak and carbon fiber.
  • There's an ongoing debate in France as to whether the cathedral should be rebuilt exactly as it was, or with a more modern touch.

A Paris architectural firm has submitted a proposal to rebuild Notre Dame with a stunning glass design, an urban farm, and a roof that generates electricity.

The plans come from Vincent Callebaut Architectures, which responded to France's open call for proposals on how to rebuild the 850-year-old Gothic cathedral. For Vincent Callebaut Architectures, the goal is to show "the new face of the Church in the 21st century," one that shows "a fairer symbiotic relationship between humans and nature."

"How can we write the contemporary history of our country, but also that of science, art, and spirituality together?" the firm said in a press release. "We seek to present a transcendent project, a symbol of a resilient and ecological future."

Under the firm's proposal — dubbed "Palingenesis," a Greek word for of rebirth or recreation — the new roof would be constructed out of glass, oak, and carbon fiber. The roof would house an urban farm that could produce an annual yield of up to 21 tons of fruits and vegetables. The glass on the roof would contain an "organic active layer" that will convert solar energy into electricity that'd be stored in hydrogen cells, from which it could be distributed throughout the cathedral.

The proposal also calls for natural light to pass through the roof and shine down on the choir.

"In conclusion, we advocate for an exemplary project in ecological engineering that feels true to its time and avoids a pastiche architecture that turns the city into an open-air museum," the firm wrote. "Circular economy, renewable energies, inclusive social innovation, urban agriculture, protection of biodiversity, without forgetting beauty and spiritual elevation: our reconstruction project feeds on such values to deliver a deep, conscious meaning."

As for purists' concerns about bringing such a modern update to the 850-year-old cathedral? The firm suggests the structure already has a long history of mixed architectural styles.

"From primitive Gothic in the 12th century to its restoration by Viollet-le Duc in the 19th century, through the radiant Gothic of the 13th century and the flamboyant Gothic of the 14th century, Notre-Dame cathedral undoubtedly arises from centuries of work and multi-faceted inspiration. As such, it is hardy encumbered by useless musings about the overlapping styles inherent in the building."

The looming superbug crisis: Politics, profit, and Big Pharma

  • Alexander Fleming discovered a fungus that produced a chemical that could stop nearly every bacteria in its path.
  • The 1950s are known as the Golden Era of Antibiotic Development. However, today, there is a looming superbug crisis because bacteria has mutated whilst we've focused on treating other diseases, such as cancer and heart disease.
  • Many companies in the pharmaceutical industry don't want to take on the expensive risk of finding another antibiotic drug. However, a potential superbug crisis may compel us to use tax-break and patent policies to incentivize them to do so.

  • This is in contradiction to the notion that an inner essence is waiting to be discovered.
  • Paying attention to everyday, mundane objects can become highly significant, filling life with meaning.

Surprising Science
  • A new study looked at why people tend to "shoot the messenger".
  • It's a fact that people don't like those who deliver them bad news.
  • The effect stems from our inherent need to make sense of bad or unpredictable situations.
