two-kilowatt rendition that heats coffee in mere seconds can't hold a
candle ray of light to HERCULES. Intentionally named in all caps by University of Michigan gurus in order to highlight its awesomeness, said laser contains 300 terawatts of power (or 300 times the capacity of the entire US electricity grid) and could "help scientists develop better proton and electron beams for radiation treatment of cancer." Still, we can't help but conclude with UMich's own description of this masterpiece: "If you could hold a giant magnifying glass in space and focus all the sunlight shining toward Earth onto one grain of sand, that concentrated ray would approach the intensity of [HERCULES]." Damn.
