The idea is basically feasible, using small devices that harvest energy from their surroundings and provide their own power supply rather like a solar calculator.

这个想法基本上是可行的，使用一些能从周围环境获取能量、自给自足的小装置，像太阳能电池板那样。

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.
