This acoustic Stirling engine seems intended as an alternative to RTGs (Radioisotope Thermal Generators) rather than as a replacement for solar cells. Such power sources are typically used in "deep space" missions where solar power is quite a bit less intense than in our vicinity.

personally if it was me i would just make a really long extention cord and drop it to the earth so someone could plug in.....
If your cord is sufficiently long, you don't even need to plug it in. You can just tap energy from Earth's magnetic field as you drag the cord through it.
