He can live on there during the zombie apocalypse.
As a capitalist I say good on you Zuck! Money well wasted.
“He can live on there during the zombie apocalypse.” Until he needs to buy another 10,000 gallons of diesel. BTW 4 engines at 291 gallons per hour is about 1200 gallons per hour, at 8 pounds per gallon that is about 10,000 pounds or 5 tons of CO2 per hour, not 40 tons. It would take 8 hours for Zuck to emit 40 tons of CO2, so he is very environmentally friendly.
One book series, Black Tide Rising, by John Ringo, about zombie apocalypse, where Zuck loaded his yacht with supermodels and a suss security team. The security folks tortured Zuck to death, raped all the girls and then tried to take all the treasure and cash aboard and leave on the smaller service boats.
They turned before they could leave, along with most of the girls and crew. Only a few girls survived, and only the ships chef and food servers survived from the crew.
