RE: Water is Not a Fuel: The GEET Engine Scam
Neat. So in your opinion, what is the most likely reason that auto makers who have built waste heat recapturing systems into their cars have used every method except stirling engine powered electrolysis?
i really wasn't aware that any cars were in production that did so. a quick google has showed me that they seem to mostly use a type of steam engine called a rankine engine. this is a new one on me . will have to look into it. another option is thermoelectric devices, presumably some kind of peltier module, something i have contemplated in the past.
as these are being used to directly charge the batteries in the case of hybrids, or add power directly to the driveshaft they are not things that would be practical for someone attempting a DIY improvement to an old car.
from wiki: Researchers at Loughborough University and the University of Sussex, both in the UK, also have concluded that using waste heat from light-duty vehicle engines in a steam power cycle could deliver fuel economy advantages of between 6.3% and 31.7%"
although this is done using a rankine engine it shows that there is validity to the concept of using waste heat to improve efficiency, even with the added weight of the system.
they probably use these approaches to avoid the inefficiency of electrolysis. they are making brand new machines and want to use the optimal solution.
for a DIY mechanic looking to improve the efficiency of his old car, electrolised hydrogen may be the only option. even if the limitations of the electrolyser reduce the impact to only 2 or 3% instead of the 30% offered by a shiny new rankine steam system, it's still better than nothing in my opinion.
There is absolutely merit to recapturing waste heat, that was never in dispute. What's being disputed is whether the method you've described can save more gas than it uses.
Only if it actually delivers any benefit. If it did, probably auto makers would be selling these kits themselves.
It may deliver no benefit at all, or a net loss.
there's obviously no point continuing this conversation. your mind is made up. anything HHO is bunk... not worth considering... ok. you should get on with the flatearthers really, the same unswervable confidence that you are entirely correct in your assumptions and refusal to listen to any contrary arguments... oh well.. peace.
Is that really why you feel that way? Are you sure it isn't because when I asked you why automakers utilize many methods of waste heat recapture, but not the one you describe, it made you realize that is probably because they tried yours and it does not deliver fuel savings?
Where'd I say that? It seems to me that you're attributing an unreasonable attitude to me as a pretense to bug out of the conversation, because what I said concerning existing methods of waste heat recapture utilized by major automakers made you realize that they probably tried the one you described, and do not use it because it does not deliver fuel savings.
I have listened to your arguments. I countered by observing that major auto manufacturers already utilize several methods for waste heat recapture, but none involving HHO.
Either they have tried it and it does not deliver enough fuel savings to be worth the weight and expense by comparison with the other methods, or no auto engineer in the world has thought of it, but you have. Is that likely?
What part of this reasoning is faulty? Am I really the one reacting in a stubborn and immature way to sound arguments?
ok. i can continue. fine by me. it just seemed to be pointless as you continually returned to your stance that the concept is fundamentally flawed and not worth considering further. its like banging my head against a wall.
you observed that no big manufacturers use it. i responded to that by pointing out that they will go for optimal solutions. that does not necessarily mean that less optimal solutions have zero positive impact.
why are you so convinced that a system utilizing hydrogen will be so much heavier than one of the rankine engine systems being developed by the industry? so much heavier that it's weight will overshadow any energy gained from the heat recycling process?
where did you say that HHO is bunk? really? in your original post. it is why I responded in the first place..
quote: " HHO, or "Brown's Gas" (sometimes "Klein's gas") claimed to exist by the water powered car people. You can read more about why HHO is bunk here,"
I imagine that's frustrating. But when somebody does not agree with you, it is not always because they are dogmatic or stubborn. Sometimes it's because your reasoning is unsound.
They could still profit from selling the kits, but they don't.
I'm just asking questions. Asking why HHO systems are not used, when a variety of other waste heat recapture systems are, is not the same as openly asserting that it's because HHO systems do not deliver enough fuel savings to be worth the cost/weight.
No, where did I say "anything HHO is bunk... not worth considering"? You have changed the wording to make the accusation more defensible. That is dishonest. I do not consent to being paraphrased.
It is worth considering. I have considered it, in the course of this discussion. My conclusion is that if it were worthwhile, it would either be among the waste recapture solutions already in use by auto manufacturers, or would be a kit that they sell.
Instead it is very widely identified by many reputable sources as a scam. Some people (not you) say this is because of a government or fossil fuel industry conspiracy. However if that were the case, the other methods of waste heat recapture would have also been suppressed.
By process of elimination, the remaining explanation (That it does not deliver enough fuel savings to be worth the cost, weight or both) seems to be the most likely. Is that wrong? If so, in what way?
I was not dishonest. you said HHO is bunk. if you believe it to be bunk it follows that you deem it to be unworthy of consideration in anything other than a negative light. in your original post the phrase "HHO is bunk" is clearly there. seems that you are accusing me of dishonesty to make your position more defensible.
sure you have considered it, all be it with a seemingly heavy bias towards the conclusion that it is a waste of time and energy.
the many sources identifying HHO kits as a scam are all referring to systems which draw their power from the car battery. I am quite happy to concede that this is almost certainly doomed to failure without some mystical deep dark magic that is beyond the realms of our usual physical universe.
you may not be openly asserting that HHO systems do not deliver enough fuel savings to be worth the cost/weight, but you are certainly implying that you believe that to be the case.
it is entirely possible that car manufacturers simply figure that the cost of developing and implementing such a heat reclamation system is not justified by the small gain in efficiency it might offer. I'm not saying it does work. I'm saying it's a possibility.
just because a product is not cost effective for a large manufacturer that is able to develop more efficient systems, that does not mean it might not be something that a hobbyist/ DIY engineer might want to explore for the small gains it might be able to offer.
I mean to say that every indication available is that there is no point, as there are several methods of waste heat recapture in use already but nobody has seen fit to bother with stirling engine powered electrolysis.
If I come off as aggressive or embattled it's because of this flag war going on. I don't mean to take that out on you.
by the way, i understand where you are coming from. bad science annoys me too. i was top of my class in physics if that counts for anything. i'm not a complete muppet. just a partial one .
Haha, ok. The idea of waste heat recapture is a good one, but there are evidently better ways to do it than to use a stirling engine to split hydrogen from water.
