Why uranium from the oceans is little more than fantasy.

When the book was written, the author suggests mining the oceans could provide 750 kWh per person per day with a world population of 6 billion. We have more than 7 billion people today but the oceans aren't any larger. The power available today is less than 643 KWh per person per day.
We have to shrink that power, however, because the author did not allow for the energy to run the massive fleets of ships needed to extract uranium - at 3 parts per billion - from seawater, or the energy needed to prepare the fuel once it was recovered from the sea.
Lunacy.
