heal.abstract	It is shown that the general momentum theory, in the form that it has been published previously, underestimates the axial force and the absorbed power, possibly by a large amount if the expansion of the wake is large. Consequently, the Betz limit, theoretically, can probably be exceeded by a correspondingly large amount. Copyright (c) 2006 John Wiley & Sons, Ltd.	en
