Somewhere on the web, it was calculated that the attractive force between two plates each having a surface area of 1 square meter and spaced 1 micron apart would, due to the Casmir effect, be attracted to one another with 0.13 grams of force. Assume machining such plates with the necessary precision were possible, further assume a spacer in the center held these impossibly rigid plates precisely 1 micron apart. The central spacer would be under compression and would be heated. This increase in temperature would be a net gain in energy. Free energy? Assume one of the plates weighed 0.13 grams. Position the other plate and central spacer so as to be horizontal and anchored to the Earths surface. Under this plate, slowly bring the 0.13-gram plate up until it contacts the 1-micron spacer. At this point the force of the Casmir effect is equal to that of the Earth’s gravity and the plate will be suspended. Anti Gravity?
