Re: Centrifuge in "World Book"

In many recent articles about the energy situation
in California I saw KW and MW used instead of KWh
and MWh. I was annoyed but it was clear, in the
context, that the authors referred to amounts of
energy and not to rates of using it.

Is it a misconception or a poor use of words?
Do they think that a huge block of styrofoam will
sink because it would be too heavy to float?
