In this talk I discuss intersecting brane configurations coming from explicit metrics with G 2 holonomy. An example of a 7‐manifold which representing a \documentclass{article}\usepackage{amssymb}\pagestyle{empty}\begin{document}$\mathbb R^3$\end{document} bundle over a self‐dual Einstein space is described and the potential appearing after compactification over the 6‐d twistor space is derived.
