Passing wireless power transfer through a magnetic resonance field enhancer (MRFE) — which can be as simple as a copper loop — can boost the transfer efficiency by at least 100 percent as compared to transferring through air alone. MRFE use could potentially boost transfer efficiency by as much as 5,000 percent in some systems, experts say.img src=»http://feeds.feedburner.com/~r/sciencedaily/~4/TeyMm2z5Spk» height=»1″ width=»1″ alt=»»/
