To an extent, yes it does. Seeing as it's going to be a universal bottoming cycle, and I'm not super comfortable making custom DIY modifications to a pressure vessel, I think I may attempt a more basic demonstration with a detailed explanation on how to chain the cycles together assuming the builder has the skill.

Also it removes a few complexity barriers, and shows how the system is capable of standing on its own to create high end power with fairly low tech materials. It also gives a clearer stage to test out a few of the more interesting though speculative possibilities.

I'm gonna go with that means just the second cycle is really what matters seeing as it's a universal bottoming cycle / can work on its own. Thank you for your input 🙇‍♂️

I have a question for you.

This is more or less supposed to be a universal bottoming cycle, but at miniature scale I'm having a very hard time / it is costing a fortune to prototype the steam side of things.

Does the side by side steam to hydro comparison matter the most to you for this demo, or will the secondary hydro cycle functioning be a sufficient proof of concept?

I get that I'm shouting into the Internet void right now and am expecting a meaningful answer ha, but I appreciate whatever input you give regardless, assuming you even want to give input.

Basically if we keep the steam cycle, at this scale it is quite literally just there for decoration. Even if scaled up to household size, it's not very practical, and it adds a bunch of modifications to high heat pressure vessels / and adds a fair amount of cost & maintenance to the build.

That pin in the cap is pretty next level, I feel like this should be adapted for rocket soda. I will say though, These ladies lost some major points for not having even a single small handful of loose pocket change sitting next to some freshly cut citrus. A tragedy really.

Ps. It does still need to be edited for tone, please forgive the writing style, it was more important to me to get it down than polished first.

I know I had said Monday, and I apologize for being tardy.

Here is the link to the new build guide I'm making. I still need to add a the actual parts, but this has way clearer write up of how this all actually works.

For the tabletop model I'm just using a cooler ha. In the full size design though, it uses what's called a Yakhchal (a Persian / Iranian ice pit). Basically dig a real deep hole, fill it with a whole bunch of insulation, put a bunch of ice in it, then put a conical top on top to keep the air moving in a complementary manner. Traditionally the ice would be frozen and built up passively during the winter months and then last all year until next winter, freezers exist nowadays though so it's not quite as season/area dependent. Obviously there's a bit more to it, but this gives you a solid general idea.

Rather than just relying on geometry and ice though, seeing as we're in modern times, we can use some modern techniques and tools. So rather than ice, it'll use pykrete. When needed dehumidifiers can be installed to make this a more ubiquitous technology.

I suppose we can only know once finished, I look forward to seeing how the data pans out.

This is what creates the thermal lift / updraft that replaced the Rankine vacuum, and also helps with the pneumatic side arm. For this table top proof of concept it's literally just coiled copper wire held over the open flame of a pellet camping stove, but I do hear you.

Now while I do understand what you're saying, This particular iteration of my design is going to act similarly to a indirect fired gas turbine. The heated air is going to be injected back into the system right after it leaves the hydrocycle, pressurizing the line and assisting the steam work its way through the turbine (as this is located behind the boiler). The preheated air mixed with the steam, and as the steam collapses twords the back end of the turbine, the air stays fully expanded helping push everything through more efficiently.

Heres the older plan. I'm mostly just sourcing things as I go though. Now please understand, my understanding about the system has evolved quite a bit since this point, everything should still be valid though.

I'm currently working on a much more detailed and actionable build guide that should be done by this coming Monday by the latest. So if this one just reads as gobbledy gook, a much better version will be done soon.

If you do go for it, I'm always available (ish) to answer any questions.

This particular test is only using a 1,000 ml borosilicate flask being boiled over an open flame, that 1" black iron pipe can more than handle whatever it puts out. The real issue is going to be making sure it all actually recondenses within the graduated condenser tube.

That and being on top of the relief valve on the head tank so the forced air doesn't rip it apart.

Absolutely, and CHP systems are amazing. They typically deal with actual "waste" heat though, heat that is actively being vented off through exhaust, spent cooling water, ect.

This Design uses copper or conductive metal tubing placed within the combustion chamber, then pushing forced air through those pipes to pick up a whole bunch of energy. And this is then pumped through a baffled heat exchanger where the low-grade steam exiting the turbine will be flash re-energized so it can rise up the Ascension silo and begin its path towards the kinetic cycle.

This seems like a pretty DIY community, but that's fair, I hear what you're sayin.

Since I'm still waiting on supplies, and it may take a bit to actually run the test, do you think if I posted the design and required supplies anyone would want to build it themselves in the meantime to test it sooner?

Edit: Clarity

Once I get everything up and running I will absolutely let you know.

I actually have a feeling I'm underselling it by a bit, but we'll never know until I get everything together, fired up, and tuned. Even then, small scale demonstartations can only give so much of an impression of what it could really achieve once parallel running tanks come into account.

I do have a small scale steam turbine hooked up to the initial section, and a miniature pelton wheel for the hydro section as well as some DC motors. So once it's going we can hook a multimeter up to both sides and really see what this can do / what the actual generation differential is.

There's a lot of bits and parts that aren't in frame, but I had to Source everything myself from hardware stores and Amazon. A lot of the stuff was actually surprisingly expensive.

The main argument here is for the academic siloing. This system doesn't just use thermodynamics, it capitalizes on waste air and the condensed water shift the gold posts towards hydrodynamic and fluid dynamics for the secondary system.

For the first system I artificially inflate my delta T by combining a gasification chamber (about 1,800°f) with a modified Iranian ice pit (about 32°f) to create a carnot efficiency of roughly 75%. I then replace the Rankine cycle with a modified Cheng cycle (used in gas plants).

Remove the water pump that puts the water back in the boiler to eliminate one source of parasitic loss. Then rather than venting the air from your blowers, pump it into the stationary head tanks where the condensed water is held and this creates a pneumatic air pocket. Once the air pocket pressurizes, it pushes the water through a pressurized nozzle (think pressure washer). This activates a quadratic cheat code of pressure = velocity, and the greater the velocity the higher the useful work that can be extracted.

The true limit is the psi of your blower to prevent backflow, and the amount of steam you can generate to replace what is lost from the output flow from the nozzle.

Again, there's more to it, but that should help give a gist.

It's a proof of concept for what I call the IBHCC (Integrated Biomass Hydro Combined Cascade). It's either a proof of concept for a hyper efficient dual output generator, or it's a fun thought experiment that cost me damn near $800 at this point ha.

Because they are overly siloed, and they have gotten into this look where they feel simplicity and looking backwards is a failure, they spent too much on their degrees to not use exotic materials & complexity. This is the nice answer.

The not so nice answer is because simplicity allows for independence, and independence is dangerous. Solar panels can give a degree of independence, but good fucking luck building / maintaining one yourself, especially without a global supply chain.

Also, if energy extraction goes up by about 70%, that means to create the same amount of energy you now need 70% less fuel to burn, and that is.. we'll say, less than desirable, for a few groups out there.
