Technicolor cosmology

We discuss limits on the lightest technibaryons arising in technicolor theories. The electric charge, weak isospin, and spin of the lightest technibaryon are calculated for several technicolor models and it is shown that, in the popular ``one family'' models, the lightest technibaryon is charged. We then calculate the relic abundance of the lightest technibaryon in the usual manner and consider their fate during primordial nucleosynthesis, galaxy formation and in stars. We show that stable charged technibaryons (or charged technibaryon-nucleus bound states) would be present on earth at levels ruled out by searches for anomalously heavy nuclei.
