Abstract
A fuel tank includes a port and an open-cell foam. The open-cell foam is configured to retain a liquid fuel by an interfacial surface tension between the open-cell foam and the liquid fuel. The open-cell foam is configured to selectively release the liquid fuel when a surfactant is applied to the open-cell foam to reduce the interfacial surface tension between the open-cell foam and the liquid fuel.
