I am in the stardust camp. PhysicsCentral agrees: The human body is about 60% water and hydrogen only accounts for 11% of that water mass. Even though water consists of two hydrogen atoms for every oxygen, hydrogen has much less mass. We can conclude that 93% of the mass in our body is stardust.
@algae1221 Not sure, but in a related topic:
My friend’s daughter recently asked how much blood you would need to make a sword from the extracted iron, and we figured assuming around 4 grams of iron per person, you’d need 250 people’s worth of blood to make a 1 kg ingot, which is a little bit lighter than an average short sword
@algae1221@MrPrincess And that is only if you efficiently extract every red blood cell from each corpse. Dispatching them with a sword will lower your efficient iron collection efforts greatly. I’d allow a 40-100 person overage to make sure. And use lots of plastic sheeting.
