One's innate skepticism should always be aroused when confronted with a pattern like this in which the only information available amounts to a well-constructed sales pitch. The combination of a good story like that of Tesla, rising electric prices, an understandable desire to reduce energy consumption or replace consumption of electricity from the grid with something produced at home, and environmental consciousness, results in a powerful incentive to believe. But one should be cautious about investing in a product of this nature without first understanding what is involved. Regrettably, one can find no such understanding in regard to Sky4Energy.
It may be that the caution expressed here is unwarranted. If so, then surely we will be treated to success stories, and the interest of scientists anxious to make a name for themselves as the solvers of all mankind's energy woe's will be drawn.
In this age of the Internet, to suppress knowledge this important, as Sky4Energy claims the electric-power interests are trying to do, is quite impossible in the long run. So if in fact the claims of Sky4Energy are valid, then that will inevitably come out. But as things are presently, caution is probably the best policy.
