Laser-induced weight variation of liquids and solids

Abstract

We performed measurements of weight in transparent materials such as liquid water, ice, and a quartz crystal when they are beamed by a laser. We detected weight variations in all cases of these materials, with magnitudes of the order of tenths to hundreds of milligrams of force. The highest value obtained was for ice, and the most interesting effect was the clear variation in weight that occurred for beams in both vertical or horizontal directions. Such a phenomenon cannot be caused by radiation pressure, reaction by vaporization, ejection of matter by heating, or piezoelectricity. The experimental results are also in accordance with the theoretical forecast proposed in our previous studies where the variation in the weight can be explained by the reaction force of the myriad of electric dipoles of the transparent dielectric previously entangled with the external environment when polarized to the component of the electric field of the propagating laser light. This new and surprising effect can be exploited to reach significant values so that it has future applications related to propulsion without fuel in aerospace or aquatic vehicles.
