From LiveScience - Strange as it seems, such negative temperatures are also “hotter than infinity”!  On a more practical level, the researchers explain the implications of such negative temperatures on, for example, future engine design:

Negative temperatures could be used to create heat engines — engines that convert heat energy to mechanical work, such as combustion engines — that are more than 100-percent efficient, something seemingly impossible. Such engines would essentially not only absorb energy from hotter substances, but also colder ones. As such, the work the engine performed could be larger than the energy taken from the hotter substance alone.
