4094 divided by 2 is 2047 male anscestors. The average volume of semen per ejaculation is roughly 3 mL on average.
2047 x 3 is 6141 mL of cum or 6.14 L of cum or about a gallon and a half.
The average fuel efficiency for cars in the US (sorry Europeans) is 25 mpg. This means if cum had the same energy density as gasoline you could travel roughly 37.5 miles on all the cum your male anscestors produced in the last 400 years.
That's only one ejaculation per male ancestor. You can safely assume that the average male ancestor ejaculated more than once. This would increase the distance traveled using the cum energy.
According to Leitzmann et al 2004 the average number of male ejaculations in lifetime is approximately 8700 times. That would be 26,1 litres of cum per male.
Edit: 2047 male ancestors would have produced roughly 53 427 litres of cum. Do we have data on energy density of cum?
With 12 generations, that would apply to pretty much everyone. It would be a statistical anomaly for anyone living today to have the full set of 4094 individual ancestors.
I'm having trouble understanding this. Why would I need 4 grandparents?... oh... because 2 had a kid and 2 had a kid... then the 2 kids were my parents... so double that for great grandparents....
Damn I just answered it to myself. Guess I shouldn't ask questions while half awake
