Every person of the audience will produce 80W of heat! (even more if dancing) Let's imagine a 2000 people audience in a rock show: 2000x80=160 kW, or more, wasted. If we will found the way to use this energy we will save a lot. In addiction to this we will also save much of the energy used for air-conditioning. |
