Re: Designing a better Gamma chamber

After extensive testing with my flat plate epoxy engine at high temperatures (seen at this link) https://www.stirlingengineforum.boydhouse.com/viewtopic.php?p=27220&sid=3fb774310b21a2bab898478b3776cf4a#p27220 , I've concluded that the cost of too much thermal transfer and cooling requirements ou...

Re: Air Lift Turbine Generator

I’m a regular listener to Undecided, but it does seem most of what he covers never goes anywhere. I had missed or forgotten your mention of that thread Tom. I chose not to pursue that design where I was attempting to harness the power of a microburst. I do believe it will work very well when charged...

Re: Constant volume compression/expansion-displacer chamber analysis-heat powered mechanical amplifier

I can only hope that the time, effort, and mental strain often at the expense of more pressing life matters has been worth it over the last 2 years. What I know is that without the active posters here I would have likely given up quickly. There is no other medium that entertains this type of specula...

Re: Constant volume compression/expansion-displacer chamber analysis-heat powered mechanical amplifier

Tom if you weren’t so dense you would see that what Matt is working on (and fool is now willing to consider it seems), will serve to validate part of your drum beat over the last decade or more. If you would stop jumping to conclusions and skipping from one wild theory to another we could actually g...

Re: Constant volume compression/expansion-displacer chamber analysis-heat powered mechanical amplifier

Tom the fact is that the world uses the basic efficiency equations that fool uses. They work for the purposes they serve. If you have any real interest in furthering scientific progress than you would do your best to conduct yourself in a professional manner and work with the 2 other people in the w...

Re: Proell Effect

Matt, per your latest graphics, I'm struggling to see how the hot side volume is "expanding" and reducing Tmax while its volume is shrinking graphically. The cold side is easy to visualize as its volume is expanding graphically.

Re: Constant volume compression/expansion-displacer chamber analysis-heat powered mechanical amplifier

Tom, everyone here brings something to the table. That is why I can bear your multiple accusations against me(aka Jack). Fool may provide constant resistance to innovation but he has the math(like Arby's has the meat). You may disagree with the math, but it is just you(us) against the established ma...

Re: Constant volume compression/expansion-displacer chamber analysis-heat powered mechanical amplifier

Thanks to all and especially Matt Brown for helping to figure this stuff out with me. I have a lot to add when I get some time.

For now, keep the arguing and personal attacks out of this thread please.

Re: Proell Effect

The major headbanger here is NOT that this violates the ideal gas law, but rather where is this magic work coming from that drives this effect ??? I can only assume that if we consider everything ideal that this magic work is passing back and forth via heat gradient during regen Matt, the way I see...

Re: Proell Effect

This graphic (cartoon - lol) says it all via comparing these 3 similar expansion processes (frames 3-4). Despite T given, Qin can only be surmised, but clearly something is awry due to this inconsistent PV work. Over the years, I've seen this irregularity pop up, but always dismissed it as a variat...

Re: Proell Effect

Vincent - do you recall commenting that after PP expansion, when displacer moves gas from hot to cold space prior 'cold stroke', that same anomaly should occur ??? (somewhere in my anomaly thread) That was genius and what enticed me to cross verify my anomaly via Cv regen while trying to quantify e...

Re: Proell Effect

. The gas is just responding to pressure and temperature differences. The gas doesn't respond to the volume. Volume change just dictates pressures and temperatures. There is a response to moving walls, as they bounce off. The gas knows nothing of load, except for the pistons response to the load, s...

Re: Proell Effect

They say the effect was not present with an open vent. It was only present with a sealed system and overall constant volume. I agree it should have been done at different temperatures, but that is really splitting hairs, as it's hard to imagine that the effect could be isolated to the selected tempe...

Re: Proell Effect

The test results seem pretty clear to me. I think they were just too caught up in the regenerator. It seems the effect is being wasted on the regenerator while it should instead be used to reduce the amount of heat that needs to be transferred through the hot plate from the original heat source. Ins...
