The new technology reduces active and standby power in temperatures ranging from room temperature (RT) to high temperature (HT) by using a bit line powercalculator (BLPC) and a digitally controllable retention circuit (DCRC).
The silver cylinder at the top is actually a small power generating device that converts micro-vibrations into usable energy, so stick one of these on, say, a ventilation duct and you should just about get enough juice to power a calculator or even an LED.
In fact, Mitsumi says these can be integrated into the RF sensor network of large air conditioning facilities, as an RF transmitter can run on very little power these days -- even less than a calculator.
The first iteration uses a nine-volt battery to force the crystals to reorient themselves and wipe out any missives, but DePorzio is confident that a small solar panel (like the one on your 99-cent calculator) will have more than enough juice to "power" a much larger model.
