James Bedford was the first person to be cryogenically frozen in 1967 in order to cheat death. The process of cryopreservation, as studied by cryobiology, is difficult, as damage can occur when trying to lower the temperature. Despite research into cold-tolerant animals and vitrification techniques, cryonics cannot currently preserve a human body indefinitely and the dream of cryonics is still on ice.
make electricity, it takes up space. Coal requires mines, and plants to convert it into electricity. Nuclear power takes uranium mines, facilities to refine it, a reactor, and a place to store the spent fuel safely. Renewable energy needs wind turbines or solar panels. So how much space would it take to power the whole world? Explore the sustainability of different power sources.
If you ever find yourself stranded in the snowy Arctic (or bored in Minecraft), you’re gonna need to know how to build an igloo. But how can building a house made of ice keep you warm?
Today, nearly 30% of all global ship traffic passes through the Suez Canal, totaling over 20,000 ships in 2021. The site of the canal had been of interest to rulers as far back as the second millennium BCE, but plans to construct a passageway were obstructed by cost, political strife, and the ever-shifting sands— until the 19th century.
Stretching over roughly nine million square kilometers and with sands reaching temperatures of up to 80° Celsius, the Sahara Desert receives about 22 million terawatt-hours of energy from the Sun every year. That’s well over 100 times more energy than humanity consumes annually. So, could covering the desert with solar panels solve our energy problems?
