The following is a paper by H. Aspden published in The Toth-Maatian Review, v. 6, pp. 3165-3171 (1987).
Abstract: There is an increasing body of opinion that recognizes the existence of tremendous amounts of energy in the vacuum, energy which offers us hope that one day we can capture this resource in our man-made machines and achieve what amounts to the dream of perpetual motion. This paper addresses this question in the light of the supporting experimental evidence, to conclude that what is a dream today is, without a doubt, the certainty of tomorrow. Indeed, the breakthrough has already been made. It is just that we have failed to see, in its proper context, what is so clearly laid before us.
Commentary: Much of this article was about the properties of force-precessed offset gyroscopes which lose weight. However, to justify the comment about energy in the abstract the following paragraph is quoted from the article:
"Together, these experimental facts confirm that there is a ghost world full of energy pervading the vacuum of space. Already the findings from research in this field are leading to the grant of patents, patents which a relativist would deem unworkable and invalid, but patents which will be the basis of investment in a new technological revolution capable of sweeping aside the mathematicians and physicists who know no other language but that of relativity. These patents include electric motors which purport to derive their energy from ferromagnetic cores which are constantly powered by whatever it is that maintains their magnetic polarization."
