Keep in mind that’s not accounting for energy consumed from neurons burning oxygen, which accounts for 20% of a human body’s consumption. https://www.ncbi.nlm.nih.gov/books/NBK28194/
minus-squareTar_Alcaran@sh.itjust.workslinkfedilinkEnglisharrow-up9·edit-21 day ago20% of your bodies energy is about 20 Watts. Normal-weight humans burn about 2200 kilocalories a day, which is about 9.2 megajoules. There are 8640 seconds in a day, so that works out to roughly 100 joules per second, or 100 Watt. 20% of that is 20 Watts for the brain.

minus-squaredisguy_ovahea@lemmy.worldlinkfedilinkEnglisharrow-up2·1 day agoWell done. So even added to the electrical consumption it’s less than an incandescent bulb. Incredible.
