We at Scholar Hero love to use knowledge to deconstruct all kinds of situations, no matter how far-fetched. The surprise blockbuster Pacific Rim, for example, raises a very legitimate question: are giant fighting robots physical possible?
For the uninitiated, Pacific Rim is a sci-fi action film about defending the human race through the use of “jaegers” (pronounced YEA-ger): enormous, skyscraper-high robots to combat an invading force of equally massive aliens called “kaijus” (pronounced KAI-joo). The film is visually impressive, but how much force would it take for a jaeger to deal a collossal right hook knockout to these giant beasts?
Luckily for us, this Scientific American article has all the answers we are looking for. At one point in the film, a particularly ugly kaiju mug says hello to a jaeger fist delivering 125 million joules of kinetic energy. That kind of blow is “like getting hit in the face with a Boeing 747 going 60 miles per hour”!
Moreover, getting that massive metal mitt up to cruising speed requires the jaeger’s elbow thrusters to produce over 7,740 kilo-newtons of force (equivalent to the power of a Saturn V rocket engine). Suffice to say, that is a lot of pepper on that punch.
