The document describes three concepts for a portable grill for fishermen and outdoor enthusiasts:
Concept A is a pouch grill that uses ethanol fuel to smoke fish enclosed in pouches, allowing intensely flavored fish anywhere. Concept B uses interchangeable wood to impart varied flavors on skewered fish flipped over an ethanol-fueled grill. Concept C is a compact, waterproof grill that uses ethanol disks as fuel and wood boards as a cooking surface for simply grilled fresh fish directly from the river.
