Comment on: Fermi Paradox
I am learning a lot about radar :) This radar is using 1 MJ, 3 millisecond pulses at ~3-30 MHz (not ~5 ns pulses at ~3 GHz), so peak power is a far cry from the 2e15 W in the article (~3e8 W.) That's why I think the 2e15 W in the article has to be peak power of all radars summed together.The average power used by all human activity is something like 20 TW (20e12 W, https://ourworldindata.org/energy-production-consumption)
