For decades that's exactly what's prevented the idea from being feasible or even just taken seriously.
几十年来,这正是这种设想不可行或甚至不被人们严肃对待的原因。
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。
I suppose further that you need a precis of the idea so you can decide whether the suggestion is feasible and warrants more exploration.
我进一步假设您需要有一个大致的想法,以使得您可以决定那个建议是否切实可行而且确保深入的研究。
