Abstract:     Apparatus providing at least one thermoelectric device for pressurizing a liquefied gas container and methods employing same are disclosed. A thermoelectric device including a heating surface and a cooling surface is used for pressurizing a container by vaporizing liquefied gas within the container by transferring heat energy from a portion of the liquefied gas in contact with the cooling surface to another portion of the liquefied gas in contact with the heating surface of the thermoelectric device to convert some of the liquefied gas to a vapor state. Liquefied gas vapor and/or liquid phase may be supplied by disclosed apparatus and methods. The apparatus may also be used as a vapor pump or a liquid pump, or fluid pump. Methods of operation are also disclosed.

    1. An apparatus for pressurizing a liquefied gas, comprising:

a container configured for receiving a gas in a liquid state therein and maintaining an elevated level of pressure therein relative to an exterior environment; and

a thermoelectric device having a cooling surface and a heating surface and configured to transfer heat energy therebetween, the cooling surface located and configured for contact with a first portion of the liquid state of the gas received in the container and the heating surface located and configured for contact with a second, different portion of the liquid state of the gas received in the container to transfer heat energy from the first portion of the liquid state to the second, different portion thereof and effect transformation of at least some of the second portion to a vapor state.
