Re: Making a stirling engine 5 kw generator
The stated goal at that time, aside from deploying these as power generators for the US military in Afghanistan and Iraq, was also to make military bases in the states more secure by allowing them to generate their own power, independent of the grid. "This is a glimpse, just a glimpse of the fu...

Re: Making a stirling engine 5 kw generator
Once the military focused attention on these engines as a potential strategic "national security" asset that could be deployed in Afghanistan, Infinia, a company that seemed to be on top of the world with a bright future ahead for unlimited expansion quite abruptly went "bankrupt"...

Re: Making a stirling engine 5 kw generator
Infinia did complete an installation at the Tooele Army base in Utah. https://vimeo.com/48084629 This is a Google Earth screenshot (taken on my phone just now) Resize_20240315_223216_6381.jpg It appears to still be in service, at least the area looks like it is being maintained. From the ground, it ...

Re: Model LTD max power effort
Just an FYI: A phonon is a "photon" of sound. From phone meaning sound or voice, and quantum mechanical wave particle duality. https://en.m.wikipedia.org/wiki/Phonon#:~:text=The%20name%20phonon%20comes%20from,phonons%20give%20rise%20to%20sound. Heat is transferred at the speed of light by...

Re: Lets beat up Carnot
I think, aside from the above considerations, this revised statement: "1 Joule is 1 Newton of force applied to a system/object for a distance of 1 meter. AKA: Energy." Is still not accurate, or not applicable in the context. Torque and Energy are fundamentally different. Simply applying a ...

Re: Lets beat up Carnot
Fool said: "1 Joule is 1 Newton of force used to move an object 1 meter of distance. AKA: Energy." Thanks to Tom. It should read: 1 Joule is 1 Newton of force applied to a system/object for a distance of 1 meter. AKA: Energy. No motion of the system is necessary. ... I'm really not sure a...

Re: Ringbom-Rice conversion?
Some additional ideas and possibilities: I have some used, or more or less "broken" or barely functional model engines kicking around that I have an idea I might be able to convert to phase change "rice" engines. And of course, some cans, mason jars and lots of other stuff I've b...

Re: Model LTD max power effort
To be clear, I've never proposed that radiant transfer has any effect on clear air; in. fact the opposite. I've only said that I think radiant heating of a heater, and radiant cooling of a cooler, that would then conduct heat to/from the working fluid, could be very significant. Apologies for any m...

Re: Model LTD max power effort
Hmm the only mechanical influence here would be the gas velocity moving through the displacer ports that could potentially reach that speed. But with a highly effective chamber, could the gas change temperature fast enough to change molecular speed by a localized mach number? If that makes any sens...

Re: Absurdly simple thermoacoustic-steam "rice" engine – What's going on here?
Generally speaking, pretty much all accounts or theories assume either some kind of "thermoacoustic" process or if a condensation/evaporation cycle is admitted the theory is that the condensation medium acts as a kind of regenerator to absorb heat to cool the working fluid, heat being tran...

Re: Lets beat up Carnot
... 1 Joule = .74 Ft/Lbs - Now traditionally a Joule is not used to quantify a static force, but that's what the internet says the conversion is, and we will need to measure power as a static force for this example. Perhaps this is where this whole example falls apart, ... There is a kind of segue ...

Re: Lets beat up Carnot
This next part is probably worth a view also https://youtu.be/5T_O6Zt5Xt4?si=rzz70E8TiiXvdR3P The main takeaway being the mass or inertia of the object matters. Another interesting point is the sum of multiple forces (or vectors) either augment or cancel each other. This helps make clear what I was ...

This is better: https://youtu.be/cPgjSeDciQ8?si=sb5uhXQLdEv2Mqc7 Clearly, with less friction, the weight would continue traveling right off the table, or with the same 1 Newton of force applied, travel many meters.
