  Senovilla has recently defined an algebraic construction of a superenergy
tensor T{A} from any arbitrary tensor A, by structuring it as an r-fold form.
This superenergy tensor satisfies automatically the dominant superenergy
property. We present a more compact definition using the r-direct product
Clifford algebra r-Cl(p,q). This form for the superenergy tensors allows to
obtain an easy proof of the dominant superenergy property valid for any
dimension.
