Does water really amplify radio signals? What is the energy source? Does the water cool down? Does it works for Wifi?

Is salty water better or worse as an amplifier?

    $\begingroup$ Why do you suggest that water might amplify radio signals? There's no reason that it should. However, you may have some additional information that you haven't included in your question. $\endgroup$ – garyp Nov 1 '16 at 18:06

  • $\begingroup$ NoEigenvalue is right. I saw those videos claiming that water amplifies those signals, but I do not know if it is a scam. $\endgroup$ – Nuwo Pagog Nov 1 '16 at 20:01

Where did you acquire the idea that "water amplifies radio waves"? Water in its natural impure form is usually conducting and damps radio waves and the saltier the more conductive it becomes. There exists no solid, liquid or gas that amplifies radio waves (Even in a maser you have to supply energy.)
