I heard that Mjolnir ' s energy could be based on the Tesseract . Not sure how true it is though . From TV Tropes Of course a blast of lightning from Mjlnir would supercharge an Arc Reactor the Arc Reactor is a reverseengineered Tesseract , and the Tesseract is Aesir technology . In case you aren ' t convinced of this , look at the rig that SHIELD has the Tesseract set up in at the start of the film . It looks almost identical to the rudimentary arc reactor Tony built in Iron Man 1 , just upsized . . Tiein materials for the films have stated that the new element Howard Stark discovered and Tony synthesized in Iron Man 2 is in fact what the Tesseract is made of at least partially . <| sep |> Protein pancakes , I ' m sure someone here can recommend a great recipe for them , honestly I just replace half the flower with whey but there must be a better way .
