Natural disasters are scary. No one wants to be crushed, burned, sunk, or eaten by zombies. That means that wealthy people who worry about this sort of thing often spend huge sums of money on things to help them survive natural disasters and other untoward apocalypses. This is a case of a man from China only identified as Yang, who created a giant survival sphere.
Apparently, the man conducted numerous research experiments after purchasing an anti-disaster yellow spherical rescue capsule. The rescue capsule the man came up with can withstand heat up to 1700°C, 350 tons of collision impact, a magnitude 10 earthquake, and tidal waves. It’s not good enough to simply survive these disasters. Yang also wanted to survive the indignity of puking inside his fancy sphere.
Obviously being thrown upside down by an attacking zombie horde could upset the digestive tract so Yang designed his capsule to use gyroscopic principles. That means that there is an outer sphere that allows an inner sphere to remain upright. No matter what happens, be it Godzilla playing Hacky sack with the survival sphere or plummeting through a giant crevice that opens in the Earth during a quake, the people inside will always remain upright.
Naturally, Yang couldn’t simply trust engineers with his life in the event of a disaster. He had to test the sphere out as well. The test process involved climbing inside the survival sphere, as it rested on a slope about 50 m tall leading into water. He then did what any person with a modicum of self-preservation would do; he had assistants roll him down the hill in the sphere.
The sphere is made from four layers of steel plate, vibration dampers, 300 high-intensity shock-absorbing springs, 75 airbags, and a thin layer of rotating liquid. The inner most orb in the safety sphere can accommodate 4 to 20 adults. It is fitted with seats, seat belts, food, water, and medical supplies. There is no air supply and since the capsule is airtight, three people only have enough air to survive for 15 to 16 days. It does have ports that can open to let in more fresh air. The sphere cost around $242,000 and took two years to build.
