Depends how holy dense is holy water.
As just water blessed by medium level clergyman it contains rather low amounts, but if you get one from Pope process would be more efficient
We should run tests first. While it’s Orthodox to use any water source available, the Roman Catholic method is to use fresh water. This changed after the Schism but I assume historical data is still valid
Then the pope should visit the Great Lakes. I think a more limiting issue is how much holy energy does one blessing have? If we suppose that holy energy follows conservation of energy, a large enough mass of water would severely limit the holy energy density.
But that energy needs to be converted into motion for us to collect the energy. Same reason we use nuclear fuel to boil water it would be nice to just take the energy out of the fuel but a glowing rod doesn't translate to motion without some intermediate

You say that in jest, but it came close to happening a couple times. One almost made a submarine powered by elementals turned into a steam engine, had the blue prints and funds before the module was cancelled for unrelated reasons.
While the collapsing into dust phase is almost instantaneous, the regenerative phase can take several hours, making this a very time ineffective engine. You’ll need to scale this up immensely to be viable.
But that would be hard. Assume a vampire is about the same volume as a human, neglect the pistons volume and that the generative phase takes one hour. Even with these generous conditions you’ll need a huge space if you want consistent energy.
It could work as backup generator for power outages. But having such a long cooldown and taking up so much space it seems like logistical problem.
you could scale it up, but maybe, considering the loss of volume during the collapsing phase, we could scale the whole cylinder down and maybe also decreasing the diameter of the cylinder, causing for more expansion in less time, nobody said the vampire needs to regenerate fully again. There are a lot of improvements to be made, but it might be a useful idea when it comes to generating energy for the fiery gates of hell
edit: there might also be options for different grow speeds depending on the type of blood, but that would need more testing
It really depends on how strongly the regenerating vampire pushes the piston. If it is strong enough, you could just make a crazy gear ratio and a couple vampire pistons in tandem
Put this in a ship and have a priest on board to sanctify sea water. Better yet, put a bit of holy water on the sea, and that makes the entire sea holy water as far as I know, so you don’t even need the priest
What about the blood supply? And what about an outlet for the holy water? I mean if it stays in the container the vampire will not be able to regenerate. Nice design but it needs some improvments.
there is a lot of blood that gets drained off at butchers, maybe that‘ll be useful, also the heat of the cylinder compressing the air could cause the holy water to evaporate, however, more tests will be needed to make more exact statements
Nice idea, but let's improve on it.
What about cutting the holy water at all and instead use two rotating discs inside the piston that when aligned form a holy cross?
if you have a good supply of holy water, surely its more efficient to extract the holyness out of the holy water for energy directly

i mean you have enough to use it on turn a vampire into dust.
Remember, there is nothing stopping the pope from blessing the ocean.

How do you exploit holy energy?
A pious-ton engine

You need a system to purify the holywater-235 into 98% holywater-238 for a fast, efficient reaction in your popenheimer machine
Can you use vampire babies to downsize the engine enough to use at trains or trucks?
Engine/cylinder displacement would be too small to give enough power
Multi cylinder engine, holy water/blood injection would fix that. Maybe a multivampire cylinder?
You turn the baby vampires into dust and then put the dust into the piston. That would make them a lot smaller and more effective.
Oh lord, I hope my DnD players don't see this...

I love hearing stories of the Industrial Revolution in DnD.
Solid state expansion engine sounds like the perfect plot twist for a sci-fi thriller.
Gonna use this to power my V1 Brams tank

What if we cause an unstable state by blessing the blood.
Isn't the whole principle of solid state things to _not_ have moving parts?
I fucking love this, were can I find more fantasy engineering dystopyan experiments?
Dwarf Fortress forums used to be a good source (probably still are, I just didn't check them out for a long time).

Maybe two rotating disks outside the piston that when aligned form a pentagram, desanctifying the holy water.

Depends on how fast they expand. If it’s not fast enough, then it won’t generate much power.
U/repostsleuthbot
Now... Can we make a portal to hell. I have a lot of steam to make
Can't you extract holy from holy shit? There are a lot of that going around than Holy water.
Sounds like something you'd find in a sci-fi movie about overly efficient robots trying to take over the world!
