A liquefied gas system and method can supply gas from a liquefied gas container more efficiently by using an external stabilizing device. The liquefied gas is located under its own vapor pressure in the lower portion of the container. As the vapor is withdrawn from the container at ambient pressure, the liquid evaporates at an equivalent rate to account for the decrease in pressure. The stabilizing device surrounding the liquefied gas container efficiently transfers the ambient external heat to the liquid thus allowing more liquefied gas to be vaporized.
