Normal power monitors use an inductance meter that clamps around a power conductor and measures the field. The down-side of these clamp-on meters is that you need to separate the power lines to measure one at a time. So the described device would need to have 2 sensors, one for each 120V (for a house) line, or one for each phase of a 3 phase commercial installation, then each sensor would wirelessly transmit to a processor which would hopefully display the useage of each leg. This would be very helpful as many residential and commercial electrical systems are significantly unablanced. Most large power users monitor their power useage by using Current Transformers (CTs) which drive the meter rather than passing the entire current through the meter itself. However those CTs typically do not communicate with any other monitoring devices so cannot provide much information beyond bulk useage. Is the described device really new technology?

If you see a hitchhiker along the road in Canada this summer, it may not be human. That’s because a robot is thumbing its way across our neighbor to the north as part of a collaborative research project by several Canadian universities.
Stanford University researchers have found a way to realize what’s been called the “Holy Grail” of battery-design research -- designing a pure lithium anode for lithium-based batteries. The design has great potential to provide unprecedented efficiency and performance in lithium-based batteries that could substantially drive down the cost of electric vehicles and solve the charging problems associated with smartphones.

Robots in films during the 2000s hit the big time; no longer are they the sidekicks of nerdy character actors. Robots we see on the big screen in recent years include Nicole Kidman, Arnold Schwarzenegger, and Eddie Murphy. Top star of the era, Will Smith, takes a spin as a robot investigator in I, Robot. Robots (or androids or cyborgs) are fully mainstream in the 2000s.
