What does OPV stand for?

But in urban settings there are considerable limitations to such an open ventilation system including noise, security, and pollution (Santamouris 2006).

The Futura features heat-conducting ABS plastic which resists heat build-up, open ventilation slots which allow hot air to rise and escape, and a 1/8-inch air space using rubber pads that lift the laptop from the Futura to allow cool air to circulate under the notebook, all combining to cool a laptop by 15% to 20%.

To improve laptop cooling over previous designs, LapWorks 1) created open ventilation slots which were previously closed channels so cool air can enter from under the Futura, 2) elongated these slots by 2 inches so hot air has a better pathway to escape from under wide-screen notebooks, and 3) created a 1/8-inch air space to let cool air circulate under the notebook with rubber pads that lift and separate it from the Futura.
