Would the plastics still form 1 solid?

What would happen if I trawled one of the oceans garbage patches (say the great pacific or atlantic garbage patches) and put everything I trawled into a furnace with an inert gas hot enough to melt the majority of plastics I picked up, what would be the outcome? I am looking to know more...

I'm a bit confused here, why would a modification of a 800MHz signals amplitude widen the frequency to 790-800MHz? And if this was the case, could I change the amplification by a smaller amount to not encroach on the other frequencies, and if so is there a limit to how slight the change has to be?

So am I right to assume that radio waves can theoretically contain as much information as they can distinguish different steps? I'm sure there is an upper limit but that it's much higher than Hz/2? Wouldn't this conflict with Shannon? Why is this the case? I would've thought if you could...

I wondered if people could clear up some misconceptions I have about radio waves. 1) If I have a 800 MHz wave, does this mean 800 Mbits per second can be transferred in theory? Could I not change the amplitude of this wave every 0.00000000125 of a second, So when a receiver is reading it...

I was reading this article today: http://news.yahoo.com/warp-drive-may-more-feasible-thought-scientists-161301109.html and in it it states this: How did they come to the figure of 10*C? Is it a matter of energy input to speed output?

I am wondering whether something as simple as cotton or spun sugar (fairy floss) could be used as substitutes if all it needed to do was fool someone 1,000 ft away?

Like you suggested, it would be done via balloon, so I guess no "launch" would be required. Is there any kind of chemical that is particularly good at looking... cloud like when it comes to these things? I mean I don't want a brown cloud, that would stick out like a saw thumb.

Wouldn't the rocket be pushing the smoke away from it? How long could this effect pretend to be a cloud before it dissipated?

Even with that being the case, is there not a solution that looks just as good to the naked eye?

Good point, I mean this type of cloud: http://whyfiles.org/wp-content/uploads/2010/03/clouds.jpg I am not interested in lightning, rain, or any other weather effects.

Is it possible to make a 10m^3 artificial cloud at about 1000ft in the sky? If yes, how real does it look? Could someone tell the difference between the artificial cloud and the natural clouds simply by looking up at the sky?

Let's say it was an unmanned aerial vehicle, I can imagine the props being metal, the batteries being dense but apart from that nothing metal that could reflect its true size (other than the envelope, if that does indeed reflect radar). The electronics/cockpit, passenger area can all be ignored...

Ah yes I have seen those devices, I assume you mean something like this: https://www.whitworths.com.au/main_itemdetail.asp?cat=144&item=74765&intAbsolutePage=1 Although blimps are probably equipped with these things, I am more interested in the blimp itself showing up on radar. Really, I'd...

Do blimps show up on radar? And if so, could somebody explain why? Is it the material they are made from (mylar/nylon)? Is it that their low density somehow gives an odd reflection?
