  The survey of a strip of sky carried out with a zenith-observing 4-m liquid
mirror can discover and observe several thousand supernovae/year to z = 1,
making it quite competitive with other proposed surveys. Because LMs are
inexpensive, and easy to build, a SNeIa survey can begin rapidly. As documented
in the published literature, the present technology, and its cost, has been
proven in both the laboratory and in observatory settings and is ready, at a
very modest cost, for a 4-m class telescope.
  As a bonus, the coadded data would survey 150 square degrees of sky to
magnitudes > 27, as deep as the deepest optical surveys but in a far larger
area of sky. There presently is a window of opportunity to make fundamental
discoveries by exploiting the cost advantage of this powerful novel technology.
