An Italian firm has put forward an idea for a green city that would be completely self-sustaining, modern, and green.
- An Italian architecture firm has proposed a sustainable city for Mexico.
- The plans call for a 100 percent self-sufficient metropolis, with renewable energy, Venetian canals, and endless green space.
- This design is one of many "smart city" proposals as of late that point to a new form of urbanism.
Electrochemical methods such as this could someday dramatically reduce greenhouse gas emissions around the planet.
- Cement production accounts for 8 percent of total carbon dioxide emissions worldwide.
- The new method uses renewable electricity to generate heat for the mixing process, while an electrochemical technique allows for carbon dioxide to be captured and stored.
- This method isn't likely to be implemented at scale anytime soon, but it's an "important first step," the researchers said.
With little progress on other avenues to preventing mass shootings, one firm has employed architecture to save students.
- A school in Michigan is being remodeled in a way to minimize the effect of a shooter should the worst happen.
- It features limited sight lines, bullet proof windows, and doors that can be locked at the push of a button.
- Some research casts doubt on how effective the plans will actually be.
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.
The lack of tall, strong oak trees poses something of a problem for the restoration effort.
- A fire destroyed Notre Dame's 115-foot roof on April 15, immediately sparking a debate on how France should restore the cathedral.
- Some argue that it should be rebuilt to its original specifications, while others say alternate materials would be a better options.
- The debate calls to mind the philosophical thought experiment known as "The Ship of Theseus."
