Abstract
We detected thermal radiation forces produced by heat flow through solid slabs suspended in nonisothermal liquids. Lateral effects are avoided, allowing a unidimensional approach. The results confirm expectations. Numerically simulated gravity-dependent perturbations are smaller than the measured forces. More precise measurements will be attempted on a European Space Agency suborbital flight in 1998.Keywords
