One mean solar day , a scientist front at those jumping bean that get sold at novelty fund and thought , “ I can do well than that . ” That ’s how the world got the “ photosalient essence , ” or “ exposure - get saltation ” — or , better yet , “ make crystals rupture themselves internally and jump around . ”
The photosalient effect may look like wanton wipeout , but it actually has a possible welfare for humanity . Solar power cells right now can only practice a sure range of light to generate functional power . This quest to make crystal burst their own insides so violently that they move came from a desire to make low - energy ultraviolet radiation light , and perhaps even in high spirits - energy violet luminosity , into something that can sire business leader .
When unwrap to even a little light , these lechatelierite can leap for millimeters . . . sometimes . As we see in this flick , sometimes the crystals leap while exploding internally but keeping their extraneous human body . Sometimes they neatly break in two . Sometimes individual , geometric shards give out off of the primary consistency of the crystallization . And sometimes , just sometimes , the crystal shatters asunder , suddenly and explosively . Not all of these reaction are evenly helpful , but they are encouraging signs , in that they read light source into mechanical power .
To understand why , the best mechanically skillful doctrine of analogy is popcorn . When exposed to get down the interior of the crystal rearrange itself dead and intensely . The outside ca n’t quite keep up and there ’s an explosion . The explosion can make the crystal leap outstrip a hundred to a hundred thousand times its own size . If the crystal shatters during the mental process , photo - induced leaping is not a practical vigor source , but one team of scientists have deal to find ways to make filaments just stoop , not break in , with the line . According to them , “ photosalient ( leaping ) solid can effectively utilise thermic or light energy and enactment as a racy and dynamically active “ skeleton ” to touch off sodium caseinate films as an elastic , conciliatory , biocompatible , rude protein ground substance , similar to stilted sinew . ” Basically , we could make light-colored - power muscle fibers . Very coolheaded , yes ?
