minus-squareSlopppyEngineer@lemmy.worldlinkfedilinkEnglisharrow-up0·5 months agoTL;DR: the total energy produced by humanity in a year. Or if you want to do it in let’s say 20 years, 5% of the total power output.
minus-squareCavemanfreak@lemm.eelinkfedilinkEnglisharrow-up0·5 months agoIt’s way less than that. 2.39x10^20 is around 4% of 5.8x10^21. Not even close to “almost as much”. Looks like the authors don’t know their powers of 10. So if we dedicate 5% of the total energy for one year it could theoretically be done.
