SAN FRANCISCO (AFP) Intel on Thursday showed off a wireless electric power system that analysts say could revolutionize modern life by freeing devices from transformers and wall outlets. Intel chief technology officer Justin Rattner demonstrated a Wireless Energy Resonant Link as he spoke at the California firm's annual developers forum in San Francisco. Electricity was sent wirelessly to a lamp on stage, lighting a 60 watt bulb that uses more power than a typical laptop computer. Most importantly, the electricity was transmitted without zapping anything or anyone that got between the sending and receiving units. "The trick with wireless power is not can you do it; it's can you do it safely and efficiently," Intel researcher Josh Smith said in an online video explaining the breakthrough.
