We perform a Gutzwiller projected wavefunction study for the spin-1/2Heisenberg model on the Kagome lattice to compare energies of severalspin-liquid states. The result indicates that a U(1)-Dirac spin-liquid statehas the lowest energy. Furthermore, even without variational parameters, theenergy turns out to be very close to that found by exact diagonalization. Weshow that such a U(1)-Dirac state represents a quantum phase whose low energyphysics is governed by four flavors of two-component Dirac fermions coupled toa U(1) gauge field. These results are discussed in the context of recentexperiments on ZnCu$_3$(OH)$_6$Cl$_2$.Comment: 5 pages, 3 figure
