"We call them heaters in that one case."
I’m pretty sure NASA used a version of this to test the resiliency of the space shuttle tiles. Not fast enough to cook tho.
Energy in general really feels weird, when you look at the numbers. Like potential energy or kinetic on relatively low speeds... And then compared to chemical energy...
Edit: Also how do you get it there? Wouldn't you need to hit it with higher frequency to start with to get to temp?
Assuming the chicken has a surface area A=1m^2 (corresponding to a perfectly spherical chicken of radius=25cm/diameter=50cm, a little bigger than usual) and is a perfect blackbody (just going to handwave this one).
with the incorrect temperature: A blackbody with T=165°C (438 K) and A=1m^2 radiates P=2090 W.
with the correct temperature: A blackbody with T=74°C (347 K) and A=1m^2 radiates P=824 W.
Also neglected is the incoming radiation from the ambient environment. Without this, the "power loss" is closer to measuring the chicken in deep interstellar space. from a room temperature environment: T=20°C (293 K) and A=1m^2 radiates P=419 W onto the chicken.
The net power loss of the cooling chicken on the kitchen counter is therefore something like 824-419 = 405W, rapidly decreasing as the temperature drops towards room temperature. e.g. at 50°C it's around 200W.
This reminds me of the old blacksmithing trick: https://www.youtube.com/watch?v=4I68Cik7ywg
