Ever wonder how much energy it takes to run the laser on the Death Star? Now you don’t have to wonder thanks to the eggheads at Science Blog.
For the earth, it works out to around 2.2 x 1032 joules. That’s a preposterously huge amount of energy! It’s a solid week of the sun’s entire power output. Dumping it in about a single second, as required to blow up Alderaan, is a very, very impressive feat. Doubly so when you take into account the fact that the binding energy is just enough to dissociate the planet into a diffuse cloud. If you want to actually blow the thing up into pieces flying out at many times escape velocity, you need much more energy.
