Recently saw the invention on PhysOrg for a device the recharges a AA battery using "waste" EM radiation from the ambient environment. In the photos, the author was placing an array of them near a power sub-station. This brings up two questions: 1) Does this create an inductive load on the source? Why, or why not? 2) Would this phenomena affect sources over long distances if there are millions of recharging units? (The article suggests using these in homes and offices to tap into waste EM radiation.) Thanks in advance for any answers.
