Exactly. Check out the pics from last weekends Boston Marathon. Try to find a single barefoot runner. Some of the best must have decided not to show up.
This is complete bull! There is no way for this thing to "to stay aloft virtually forever" without some sort of external energy input. Entropy 101.
On a side note, does anyone know how stinking cold it is at 50,000 ft. I don't know for certain but I'm sure is a really small number (in K of course). The heat loss from such a ship must be significant at these elevations. Does anyone know how these folks propose to keep their passengers from freezing? They can't always fly in the sun; they will need some sort of energy source to keep the temperatures at levels suitable for human existence. No, their magical compressors won't be able to do much about this
