  We discuss the strength of the trilinear Higgs boson coupling in technicolor
(or composite) models in a model independent way. The coupling is determined as
a function of a very general ansatz for the technicolor self-energy, and turns
out to be equal or smaller than the one of the standard model Higgs boson
depending on the dynamics of the theory. With this trilinear coupling we
estimate the cross section for Higgs boson pair production at the LHC. This
measurement is quite improbable in the case of a heavy standard model Higgs
boson, but it will be even worse when this boson is dynamically generated.
