MIT Professor Dan Nocera believes he can solve the worlds energy problems with an Olympic-sized pool of water. Nocera and his research team have identified a simple technique for powering the Earth inexpensively by using the sun to split water and store energy - making the large-scale deployment of personalized solar energy possible.

Eric Giler demos wireless electricity at the TEC conference.

Eric Giler wants to untangle our wired lives with cable-free electric power. Here, he covers what this sci-fi tech offers, and demos MIT’s breakthrough version, WiTricity — a near-to-market invention that may soon recharge your cell phone, car, pacemaker.

Spencer Ahrens, a 23-year-old mechanical engineer, was on MIT’s campus last week, holding a wooden plank, surrounded by onlookers.Slowly, he turned that wooden plank before a series of mirrors that had been placed inside an aluminum frame, until the wood caught fire.That was quite a moment, recalled Matthew Ritter, one of the onlookers.
“Let’s just say it was a small combustion for wood materials, but a giant explosion of solar energy,” he said.
