The projection of the sun's rays concerns the same surface throughout the day, since the sun "rotates" around the pipe (it is therefore not the same part that is heated, but the surface does not change).

Re: Recycling plastic bottles PET thermal solar panel
This is not exactly true from sunrise to sunset because at the wide angle a tube makes shade to the tube next door, but it still makes a good zonz in the middle of the day has constant power
There is somewhat the same effect with vacuum tubes, but I find it regrettable that on ordinary vacuum sensors the tubes are mounted too tight ... as in any case one does not cover a whole roof of vacuum tube, It would be better used if it were more discarded so as not to shade

Yes, it is true only approximately: I had simplified a bit for the understanding of the phenomenon.

Tube sensors (vacuum or not) are less efficient than the plans during the summer period: Solar-thermal / change-of-sensor-solar-planes or tubes-vacuum-t4998.html # p74761

Is industrial plastic recycling a myth?

It's more than a myth, it is schizophrenia in the sense of a disconnection with reality!
The article also underlines:
Recycling is used at two levels by manufacturers / traders:
- on the one hand, they are concerned with always producing more, this is their priority and not recycling, in other words taking into account the consequences at all levels of their production;
- on the other hand, we must repeat it and insist, we come to make the consumer feel guilty, who would consume too much and polluting goods!
This reversal is serious, because it amounts to making the producer a sort of victim of the "consumer society". Nothing more unacceptable "
This observation, which has been recurring for years, raises questions:
we are all in the same boat which sinks gently, some try to bail out while others continue to worsen the announced sinking to still scratch at some financial benefits, just before sinking into the abyssal depths of the approaching anthropic cataclysm Faster and faster...
This is one of the great existential questions that humanity must ask itself: Is it better to die with your pockets full or empty?

Christophe,
"Full pockets" ... it is not with ash from charred plastic waste, it is something else that it is about, great naive that you are!

Re: Recycling plastic bottles PET thermal solar panel
A lightweight plastic that burns well is no ash!
But of course it is better to be poor than rich ...
