China’s Forbidden City rocks were transported on ice

Huge stones that make up parts of China’s Forbidden City were transported along artificial ice paths lubricated with water, a team says.

That’s despite the fact that wheeled vehicles had been developed 3,000 years earlier.

The colossal city was built in the 15th Century by workers at the start of the Ming dynasty.

Writing in PNAS journal, the team says that wood-on-ice sliding was more reliable than using wheels.”

Could this incredible engineering project save the polar ice caps?

"While changing human behavior and reducing carbon emissions offer long-term solutions to human contributions to climate change, American architect Derek Pirozzi wants to see an immediate solution for saving the polar ice caps. He’s proposed the Polar Umbrella, a buoyant super-structure that would both protect and replenish Arctic ice.”

Using 45,000 Milk Cartons, This Is the Largest Recycled Structure Ever Made
“Ever wonder who holds the Guinness World Records’ title for largest major construction to be built out of recycled materials? The answer is this beautiful “Brik Pavilion” built from 45,000 milk cartons in the province of Granada, Spain. Created to coincide with World Recycling Day, the structure consisted of a large wall spanning 100 feet long, and a tower running 23 feet high.”
