But these questions have no bearing on whether the effect is real or not. During the Vanguard era of US rocket development in the 1950s, rockets were extremely difficult to reproduce and they were so badly controlled most of them exploded. However, no one suggested that rockets do not exist. Reproducibility and controllability have ZERO, ZIP, NO relevance to whether the effect is real or not. They only determine whether its commercially useful, or cost-effective. Rockets are not still not well controlled. They often explode, so the insurance rates are high. You pay extra on your satellite TV bill to cover this. Some types of semiconductors in the 1950s had low reproducibility rates which meant they remained more expensive than vacuum tubes for several years. - Jed
