Some basic facts present standard physics fully understands and

Blackbody radiation: At a room temperature of 297 Kelvin (74.93 F,
23.85 C) both sides of a thin sheet of opaque material radiates
882.4 Watts per square meter.
Actually, the above is off by half. Each side of the square meter
radiates (5.6705119E-8 kg/(s^3 (deg. K)^4)) * (297 deg. K)^4 * (1
m^2) = 441.2 watts. The difficulty with trying to capture this
energy is that an antenna at the same temperature will be similarly
radiating.
