Slava Vitsev asked the Naked Scientists:
I think your site is the best among the scientific and errors are very rare. But I think that in a podcast on October 23, 2011 there is an error in the answer to the question: Can we use moonlight to start a fire?
Moonlight is not a black-body radiation. It is the light of the sun reaches us reflected from the moon likely as from a mirror. Visible light has a frequency range with an energy of about 0.5 eV, which is equal to a temperature of about 5000 degrees. Therefore a large telescope would be able to burn the paper.
Kind regards,
Slava Vitsev
