We propose two schemes to entangle macroscopic ensembles of nuclear spins in quantum dots by means of electronic transport through the dots. The first scheme uses the quantum non-demolition (QND) measurement of the nuclear spins interacting with a stream of spin polarized electrons. For the second scheme we exploit the dissipation induced entanglement due to the incoherent electron current through the dots.
