Present and Past Technology

Present                                                          Past

    Current technologies are graphene, propylene glycol, gyroscope technology & Sorbothane.

  • Thin layer of pure carbon
  • Atoms in honeycomb form
  • Stack a few layers of graphene to have graphite
  • Currently the strongest material on earth
  • 1 sheet can support an elephant
  • Scientists had to separate graphite layer by layer until 1 layer remained to make graphene
  • It's 200 times stronger than steel and 1,000,000 thinner than human hair

Propylene glycol:
  • Form of mineral oil
  • An alcohol produced by fermentation of yeast and carbohydrates
  • Used in engine coolants and antifreeze, airplane de-icing, polyurethane cushions, paints, enamels and varnishes
  • Cushions are made of polyurethane for comfort
  • Propylene glycol gel doesn't freeze, not even at high altitude 

  • Devices that use gravity to orient themselves in one continual direction
  • Made of a freely-rotating disk called a rotor sitting on top of a spinning axis in the middle of a bigger and more stable wheel
  • Need airline seat to point in one direction for safety  and comfort  

  • The underside of the SSS 1.0 can be coated in Sorbothane  
  • Also known as a viscoelastic urethane polymer, which absorbs 94.7% of shock
  • Sorbothane acts like a liquid when hitting something, even though it is a solid when at rest
  • Sorbothane is a thermoset, polyether-based polyurethane material
  • Can dampen vibrations
  • Can work when the temperature is -29 ℃.


     The past holds ejection seats and low-tech gyroscopes, as well as the structure of graphene.

The Creation of Graphene:
  • Began as block of graphite
  • The block was cut into very thin layers
  • The scientists realized that they had found graphene
  • Discovered by V. Kohlschütter and P. Haenni

Ejection seat:
  • Saved over 7,500 lives
  • Used to have a handle at top
  • Handle moved to bottom for the ability to reach it more easily
  • Fitted with a parachute
  • First ejection seat was demonstrated in a jet known as the Meteor

Low-tech gyroscopes:
  • The first gyroscope was the well-known toy called the top
  • Gyroscopes have a rudder that spins
  • Gyroscope technology has been used for many things
  • Was made using polyol and isocyanate
  • Designed to absorb shock
  • Deformed easily
  • Recovered slowly
  • Acted like a liquid when hitting something 
  • Acted as a solid otherwise 
  • Invented by Dr. Maurice Hiles
