staska - here's the hot/cold gamma comparison within same values where both gamma have same PP volume - enjoy

When is air being vented to atmophere by the Wilcox engine? The first half of the compression phase? Yes, but I think first half of the compression piston stroke would be a better description. The output per cycle was likely so low that it required a team of horses to spin up the flywheel prior sta...

So, eff was ~25% before alternator. A table like this tells one story, but a PV would tell another. Considering how much time and moola went into this, I doubt we can expect a stand alone CHP anytime soon. I'm all too familiar will this NASA type of stuff, and currently sitting less than 2 miles fro...

The capillary tube is the "orifice". It's diameter and length must be sized to the pressure difference, and flow rate. Longer and narrower for lower flows and higher pressure drops. Shorter and wider for higher flows an lower pressure drops. Higher pressure drops are needed for higher tem...

At the start of the compression stroke (in a Stirling engine) the working fluid is cooling and contracting and the piston is driven in by atmospheric or buffer pressure. And where is the heat from this "cooling" going ??? Towards the end of the stroke heat and pressure build up suddenly a...

According to an article by Nikola Tesla some of the HEAT passing through a heat engine is CONVERTED into some other form of energy (mechanical motion, momentum etc.) and so never reaches the "sink". He envisioned that given a heat engine running on Ambient heat with great enough efficienc...

caught it prior edit...Your a bigger blowhard than "fool". AC units are fairly cheap these days, except for electricity. When I lived in Phoenix (early 1960s), the population was small and most people had swamp coolers and they worked great. However, as the population exploded, all the law...

According to Tesla's theory... If we first ran the Peltier module to cool the bottom plate. (Keeping it insulated of course, to preserve the cold). The engine could then run on the surrounding ambient heat, and with perfect insulation and a 100% efficient engine, it could run indefinitely. He recog...

Let me ask you fool. Do you doubt that evaporative cooling (using water) can reduce the temperature of the air? i.e. "swamp cooler". Why, OMG, how is that possible! Water boils at 212°F !!!!! You couldn't possibly use evaporating water to cool below 100°C !!!! Evaporative cooling with wat...

Could i ask for source of this information ? I've been studying this stuff for 50 years... Alpha have 1.41 more cc at 90 phase angle. Beeing all other equal. Gammas do.suffer from lowest working fluid beeing heated and putted to work. Or all extra dead space is cushion to absorb pur precise pressur...

One major difference...hot gamma has more output for same regen than cold gamma and hot beta has more output for same regen than cold beta. Even with excellent regen, this is usually a big difference in overall efficiency. An alpha has the lowest regen and the best torque (everything else equal). h...

Stroller - I think Vincent is suggesting a bang-on demo akin a sloooow isothermal expansion lifting a rock. In this manner, the only 'fuzzy belief' required is that an isothermal expansion has no change in internal energy, whereby all heat input 'must be' converted into work, no ands, ifs, or buts. ...

I'm not sure what really defines either, but by my logic it's a Beta for the following reasons. 1- Both piston and displacer share the same exact bore and axis of travel. 2- Most importantly, the displacer and power piston occupy the same space at various points of the cycle, a feature reserved for...

The average bulk temperature is what the engine reacts to. Any pressure sensors will react similarly to the engine, so it is a fair representation to use for analysis. The sensor will react as fast or faster than the engine. The theoretical pressure change due to volumetric change in an unheated en...
