The EtaPackLite runs on pressurized LP gas and is rated at 80 percent efficiency. It weighs 21 ounces and comes as a complete cook system, including a stove base with burner, wind screen, serving bowl, and a 1.2 liter pot with a lid that doubles as a colander. All components, including a 100-gram fuel cartridge, nest in the pot. The EtaPackLite will be available for Spring 2009 and will retail for $115.
