$this->bbcode_second_pass_quote('yesplease', '')$this->bbcode_second_pass_quote('Ludi', '')$this->bbcode_second_pass_quote('yesplease', 'U')m, if energy broken down into heat was really irretrievable, we wouldn't have ICEs or power plants. They both burn FFs or whatever, turn them into irretrievable heat, and retrieve mechanical, then electrical power, in different proportions from that irretrievable heat.
After you have used that energy (heat) to run your power plant, how do you retrieve it?
That's just the problem, if it's irretrievable heat, as like_the_dinosaurs claimed, it can't be used in the first place, it's irretrievable after all.
$this->bbcode_second_pass_quote('Ludi', 'T')he energy (heat) has been used for work. How do you now retrieve it? If you can not retrieve it, in what way is it not "irretrievable"? If it is retrievable, isn't that a perpetual motion machine? Where is the evidence of such a thing?
<<<< never took physics
Like I said before, if it's irretrievable, it can't be used for work, that's what irretrievable means. Then again, saying it's irretrievable is bunk. In general, the amount of work available depends on the difference in temperatures given whatever material limits are present. A saying like "irretrievable heat" is irrational nonsense, and seems to be indicative of this forums unfortunately. It's not about heat having some characteristic that makes it irretrievable, if it was, combustion (among other things) and the universe as we know it wouldn't exist. It's about what kind of difference in temperature we're looking at given whatever engine. Different engines are designed to work under different conditions, and so on... Practically speaking, the
lowest temperature difference that can be exploited is a degree F or so.

Wouldn't even!
I'm still interested in how an internal combustion engine retrieves the irretrievable heat btw!

You and a lot of other technocorns!

Seriously! If I were just like those doomcopians I would understand how an ICE converts liquid energy into irretrievable heat, then retrieves it. Only the true believers must be able to retrieve the irretrievable!

$this->bbcode_second_pass_quote('yesplease', 'I')n terms of externalized costs it's certainly a detriment, but from the point of view of scarcity causing significant problems, we have a long way to go due to how wasteful people are.
Um, scarcity is already causing huge problems in some parts of the world. Wastefulness is not a virtue & treating it as such is morally reprehensible in my opinion.
