People should not be so ignorant as to automatically ban everything that sounds far-fetched. Virtually everything technological seemed far-fetched at some point!
Actually, one can get many metals to exhibit a fifty-percent reflection at angles shallower than five degrees. Some specially designed materials have will reflect fifty percent at angles as steep as 15 degrees. This is according to peer-reviewed, published papers by Dr. Allred at BYU in Utah and his colleagues. (He did some of the optics for NASA Space Probes!)
It would be nice to get better reflection characteristics, but five to fifteen degrees is quite sufficient to generate serious force differences; the forces of the strength of the quantum flux at wavelengths that are greater than or equal to 5 nm are quite considerable.
As to the reality of the Quantum Flux, it is widely held, in peer-reviewed literature that the Casimir Force is nothing more than induced differences in the radiation pressure of the Quantum Flux. At first, it does indeed seem impossible to tap into these forces since they are equally strong on both sides of the plate; nonetheless, it is a well-know fact that reflected-electromagnetic radiation imparts twice as much momentum to a surface as absorbed-electromagnetic radiation.
That is why the electromagnetic radiation of the quantum flux can potentially impart more momentum to the somewhat reflective side of the plate and less to the mostly absorptive side--In other words, a net force!!!
Please let me know if any of you have any leads on the metallurgy part of this. I just need to produce a few samples of Nickel-Aluminum alloy to make these surfaces out of.
