We show that the van der Waals (vdW) and Casimir forces between neutral particles can be enhanced by many orders of magnitude upon changing the character of the force-mediating vacuum photon-modes. By considering two induced dipoles in the vicinity of any standard electric transmission line, where photons can propagate in one dimension (1d), we find analytically that the interaction scales nontrivially with the inter-dipolar distance, resulting in much stronger and longer-range interaction than in free-space. This may have profound implications on the non-additivity of vdW and Casimir interactions in many-particle systems, and open the door for Casimir phenomena in 1d. We discuss the possibilities of measuring this effect, e.g. in a coplanar waveguide line.
