Talk:Plasma deep drilling technology

A self-contradiction in the article.[edit]
We have near the beginning of the article, in the general description:
"It has lower energy efficiency than some of the other technologies"
and then later on, under Advantages:
"Higher drilling energy efficiency."
These two sentences would appear to be mutually contradictory. A bit of further explanation, please. Old_Wombat (talk) 08:53, 7 September 2011 (UTC)
