Other studies show that men and women lie with equal frequency--though women are more likely to lie to make other people feel good, while men tend to lie to make themselves look better.
For example, rather than purchase expensive ultra-efficient motors, low cost opportunistic additions to old fans and pumps such as variable frequency drives and demand controls can deliver equal energy savings at a fraction of the cost.
The sensors work by detecting extremely low-frequency electrical activity over a distance of 5 microns (one micron being equal to one millionth of a metre).
