  Monovalent non-transition metals are robust Fermi liquids. They defy
superconductivity even at lowest temperatures (Li is a minor exception:Tc
$\approx$ 0.4 mK). However, Thapa and Pandey \cite{ThapaPandey} have recently
reported signals for ambient temperature granular superconductivity in Ag
nanoparticle embedded in Au matrix. We develop a theory, where competing
superconducing, CDW and SDW orders lose and get confined (go off-shell). They
leave behind a robust Fermi liquid on-shell. \textit{A single half filled band
crossing the Fermi level} provides a number of special k-space regions for
\textit{singlet stabilizing umklapp pair scattering and superconductivity
stabilizing repulsive pair scattering}. Carefully designed perturbations could
deconfine a confined superconductivity. We suggest that electron transfer
(doping) from Ag nanoparticles to Au matrix (with a higher electronegativity),
quasi 2d structural reconstructions (e.g., 9R structure) at Ag-Au interfaces
etc., bring out confined superconductivity. Beneath a calm Fermi sea, strong
supercurrents may exist in several metals.
