The Solaire line of infrared grills from Rasmussen Iron Works grills faster with ceramic burners that emit infrared heat (between microwaves and visible light on the light spectrum) powered by the usual propane. A Solaire grill's burner takes only three minutes to heat up and cooks food 50 percent faster than a typical gas grill, according to the company.

Because the food cooks from a direct source of high heat (temperatures range from 340 to 950 degrees) evenly spaced, food is supposedly seared more quickly and retains more moisture than it would with gas or charcoal grills. The average hamburger takes seven minutes total to grill, according to Solaire's own directions.

While the Solaire portable sells for about $323, the 27-inch grill goes for $1,209 and the 56-inch grill for about $5,559.
