There was not an overall net gain.

Direct from the source http://1.usa.gov/1e4Na9Q.

8 kJ out from 1.7 MJ (1700 kJ) in. At the end of the month they were able to get 14 kJ. I believe they are referring to the energy released within the hohlraum.

Also, if you are interested there are privately funded companies doing this, General Fusion (http://www.generalfusion.com/) and TriAlpha Energy (secretive and funded by the Russian govt., but in California). The VC fund I work for has invested in GF and obviously we think there is promise :)
