minus-squareCavemanfreak@lemm.eelinkfedilinkEnglisharrow-up0·4 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.
