Physics, Astronomy & Cosmology / Are Photons "pushed" or "pulled ?

Just a muse, but are photons and other parts of the electromagnetic spectrum pushed or pulled after propagation?

I know it's a strange question, but please treat it with the respect and seriousness it deserves!

Technology / How do crystal electrical generators work?

« on: 10/02/2013 19:45:44 »

As most people with an interest in science will know. The crystal in a crystal radio generates an electrical current when it resonates with a radio wave. I know that the current of these devices are very low but nevertheless they produce it. But imagine for one moment for the ease of explanation that we had a crystal that produced .25 of a Watt when it received a signal from a transmitter outputting 1Kw / 1000 Watts. If we then had 4000 of these crystals they would be outputting collectively what they received, is this not so? But what would then happen if we arranged 8000 such crystals around our 1Kw transmitter? Would we not be generating 2Kw from an input of 1Kw meaning that we have achieved that "O" word that is forbidden in respectable science circles! I have in my deliberations considered such  things as Radio signal decay over inverse square law. It is perfectly possible to put Millions of crystals within the full 1Kw register of the transmitter. I am currently in the design phase of building a crystal generator with a 1Watt transmitter and 1500 1N34A Germanium diodes.
I would like to hear peoples opinions and ideas.
