Abstract
In the first of a series of three lectures we discuss ways of measuring the power available to feed the jets in powerful FR II radio sources. For unobscured radio-loud QSOs we present evidence that this power is directly related to the UV-optical luminosity, or probably more accurately, to the power radiated through processes of accretion in a strong gravitational potential. It has been suggested on theoretical grounds that powerful radio jets are a necessary component of the central engine. It then follows, from the similarity of the optical-UV power output, spectral energy distribution, and emission-line spectra of radio-loud and radio-quiet QSOs, that radio-quiet QSOs have the same power available to feed jets as do radioloud QSOs. This then leaves us with the puzzle of why we do not see the powerful jets in radio-quiet QSOs.
