 Reich was much encouraged by the meeting and hoped he would be invited to join Princeton 's Institute for Advanced Study . During their next meeting , he gave Einstein a small accumulator , and over the next 10 days Einstein performed experiments with it in his basement , which involved taking the temperature above , inside and near the device , and stripping it down to its Faraday cage to compare temperatures . He observed an increase of temperature , which Reich argued was caused by orgone . One of Einstein 's assistants pointed out that the temperature was lower on the floor than on the ceiling . Einstein concluded that the effect was simply due to the temperature gradient inside the room . " Through these experiments I regard the matter as completely solved , " he wrote to Reich on 7 February 1941 .
