Ideas: 'Atomic Trampoline' Armour/ Pat on the back space suit device/Sterling Engine Applications/ Diamagnetic bowling game

Invention Idea: Atomic trampoline armour - If a ball bearing will bounce off of an 'atomic trampoline' (amorphous metal) as high as a rubber ball and keep bouncing for a long time then perhaps a bullet hitting an atomic trampoline would bounce off in which case you could make 'atomic trampoline' armour plating that would make bullets fired at it bounce back into the face of the enemy.

 

Pat on the back mechanical space suit propulsion- What would happen if an astronaut, floating in space, had a mechanical or robotic arm on the back of his space suit that would give him a hard pat on the back. Wouldn't that pat on the back, if it was hard enough, push him forwards?
But why would you need such a silly form of propulsion?: I was thinking about an astronaut without a jet pack, floating off helplessly into space without any way of stopping himself or pushing himself forwards, some mechanical device to push or kick him from behind might save his life.

 

 

Hypothermia/Arctic Explorer Heater -
Because Stirling engines can be powered by cold you could use them to power emergency heaters to provide warmth to victims of hypothermia or heating for arctic explorers
Candle powered electric light/electric generator -
People always keep candles incase theres a power cut but if you had a stirling engine driven generator then you could use the heat of those candles to power electric lights and other electrical devices during power cuts.
Combined Cold Weather Heater and Warm Weather Fan -
Because a stirling engine can be powered by both heat and cold you could have a combined heater and fan powered by the engine so that, no matter what the weather, you can stay comfortable.
Hot air powered Motor Hot Air Baloon -
You could have a hot air balloon with stirling engine powered propellers so that you could use the same hot air both for levitating the balloon and for propelling it.
Ice melter/breaker -
Because sterling engines can be powered by cold you could have an electrically heated ice melter that is powered by cold air and ice.
Permanently airborne heli-drone-
This is a drone like an electric helicopter that is permantly powered by hot or cold air so that it can remain airborne for very long periods of time
Energy Multiplier
A sterling engine powered generator is placed next to an ordinary generator. The ordinary generator creates heat as a bi-product which then powers the sterling generator so you get twice as much energy.

 

Sport/Game Idea -Diamagnetic Bowling Diamagnetic bowling is a game that uses diamagnetic levitation.
In this game the playing field is made of magnets arranged to create a diamagnetic field.
Discs or Pucks of pyrolitic graphite are knocked across the surface of the diamagnetic field either so that they knock into other dics or hit static targets.
