NEW SCIENCE: AT LAST, AN ANSWER TO HOW EGYPTIAN PYRAMIDS WERE BUILT
- How an ancient society was capable of building colossal pyramids has long been a source of mystery and wonder. Scientists seem to have found the answer. Here's what we know:
- Built 4,700 years ago, the pyramids sit at the edge of the harsh Sahara Desert, far from the Nile River
- Attempting to build colossal pyramids, which would have taken 1000 years, has puzzled experts for years
- Experts from the University of North Carolina Wilmington seem to have solved the mystery
- Soil samples and satellite imagery show a long-lost branch of the Nile coursed through the area of the pyramids
- This would have stretched an area of greenery, making it more amenable for big construction
- The long-lost river branch would have been needed to transport key materials
- It seems the mysterious truth was hidden under the blowing sands.
ICELAND'S GIANT VACUUM TO SCOOP UP CO2
- The world's largest plant designed to pull CO2 out of the air just started operating in Iceland. Here are some key facts:
- Called Mammoth
- Operates like a giant vacuum pulling planet-warming pollution out of the air
- Run by Swiss-based Climeworks and is located in Hellishieldi, Iceland
- Largest commercial, direct air capture (DAC) and 2nd one built in the world
- Powered by Iceland's green thermal energy
- The carbon stripped out of the air is buried or transformed into solid objects
- Carbon capture technology is criticized by some as expensive and unproven at scale
- Climateworks hopes to remove 1 million tons of carbon from the air per year by 2030 and 1 billion tons by 2050.
