Electromagnetism is still vastly mysterious to most, and yet we have only 5% of our students enrolling in science/engineering in college, which is where students get to check out some of EM hands-on with useful equipment. EM is going to become even more mysterious to even more as a result, and we will find that most will not be able to understand the first thing about the topic.

It sounds like they are not creating energy, but harvesting it from some source that they do not recognize. Perhaps minor fluctuations in the earths magnetic field, or from solar flares. That is, if this is not a publicity stunt.
