The Di Pietro Motor

Note, April 23 2021: Brian and I recently clarified that MDI and Di Pietro are two distinct air motors, made by separate companies. In the following, he meant to refer to the Di Pietro motor.

MDI is the company that Di Pietro made in Australia. He has a version of the air vane system similar to air powered tooling of that variety. It's a simple system that I recommend researching. Very efficient and difficult to break. Di Pietro made a motor that utilizes the same strategy, but created it in an almost completely backwards fashion to that of the air vane system. It's quite genius. The internal bearing that transfers the air pressurized movement to mechanical advantage barely spins at all while the off center displacement pushes the cam and driveshaft. By doing that, as opposed to utilizing the pressure to push the cam and driveshaft directly (as is the case with air vane systems) the wear and tear is extremely reduced, resulting in a couple of upgrades. The most prominent to me is the efficiency of thrust to output ratio. In simplified terms, the motor is extremely efficient due to the precise tolerances allowed from utilizing a bearing internally. Secondarily, the motor does not require lubrication, but has the capacity to spin at very high revolutions. It's almost as if the bearing itself becomes the lubricant. The Di Pietro motor is the most efficient motor I've ever seen, and I would like to implement it in farm equipment, and power it with my windmill technology that I developed years ago through a pressurized tank system that the windmill and/or solar panels would feed. It's a completely self sustaining system from "cradle to cradle" when one understands machining and casting. The parts are all aluminum, which makes a coal (wood) powered foundry the final stages of contention to the overall system. If the sun is making trees, the entire system from power (the windmill) to output usage (the engine) is accounted for. When the tanks wear out, forge new ones out of the old material. When the engine wears out, cast billets and machine a new one from the old material. Etc etc etc. Cradle to cradle. That's why I explain that a diverse background is essential to completing loops, but I also reiterate that I see things differently than most. There are no breaks in the chain of creation. Most people that fancy themselves as craftsmen or inventors, usually leave out aspects of their creation that is taken up by a finite resource: crude oil, grid tied electricity, NG, etc. Since they've had it their entire lives, the constant implementation of finite resources is taken for granted. I've been on a mission to destroy that dereliction for decades, which is why I always seem to draw out the most inferior people with the largest superiority complexes. It's not just about building Holy Grails and Pyramids, although that too fits the same paradigm. I have many systems within the confines of my experiences that can make humanity self sufficient beyond the usage of finite resources... BUT, nobody seems to be able to see what I see. Thusly, the lake of fire continues to burn uncontrollably. Remorse again for the wasted potential.

Anyways, just wanted to explain that. DMI was a typo. The first time I tried to implement the MDI engine was about 15 years ago. I had just finished remodeling a condo and had about $8k to spend. My childhood friend Nathan, and my new girlfriend at the time got the spiel from me about setting up a taxi company with the funds using those motors. They couldn't see what I could, however, and the project died. I've not forgotten them, though. The time I spent on the farm with Shane reinvigorated the technology. Imagine an entire town using them... That's what I envisioned 15ish years ago. The real kicker is in doing research on these motors using steam to power them; not just air pressure. A more recent development (circa 2018) was using the geothermal placement strategy, powering the system with a nitinol engine, connected to a cavitation water heater... and powering several of the MDI engines with the steam. That entire system is also cradle to cradle, except for the manufacture of the nitinol wire itself, which I was extremely close to completing. It requires a vacuum system due to the alloy properties inherent when nickel is exposed to oxygen at those temperatures. I could do it, but it would take a bit of experience. At the end of that system, I would also implement radiolysis for the remainder of steam exiting the MDI motors for hydrogen conversion. Again, I could do it, but I didn't have direct experience. I do have a working knowledge of everything necessary to complete the loop, though. Truly carbon neutral, off grid, sustainable indefinitely... Divine. Sad, though. No monetary profit involved, thus, nobody in hell cares.

The MDI engine is the transferred version of the power generated from the cavitation water heater (steam). The cavitation water heater gets its energy from the nitinol engine (centrifugal force/inertia) the nitinol engine gets its energy from manipulating heat. The easiest way to manipulate that heat is by utilizing a geothermal perspective. In other words, taking the system out of the atmospheric fluctuations. Within a cavernous structure, at least 8ft down in most latitudes, the ambient air temperature remains a constant 60degrees farenheit. Your cooler water would remain sufficient. To start the process of warming the water above 72degrees farenheit, one could use solar, or some other Satanic energy. Once the cavitation water heater is running, the excess heat could maintain the reaction. 

If... you wanted to utilize the wind (solar energy), or direct solar energy to power an MDI engine, you could do that, but the implements are intermittent and dependent on clouds, wind, weather etc. To store energy for powering the MDI engine (air pressure), all you would need is a storage system, or air pressure tank. Then you would power a condenser directly with a wind or solar powered generator, and store the energy in a tank. The tank's pressure would power the MDI engine. You could also power the condenser with hydro power, which would be less intermittent. The idea is to get the least intermittent system from start to finish. That system is a nitinol engine, powering a cavitation water heater, that powers MDI engines. Not only is that the most efficient form of energy transference, but the engines and nitinol itself are the least restrictive on recycling the components. Solar panels break down and are difficult to reproduce. Wind generators have the same stigma. Not impossible, just wasteful. More foundry work and machining over their lifespan than that of nitinol (as long as the cavernous structure is utilized). 

If one were to try to make a nitinol system work while dealing with the atmospheric fluctuations of the surface of Earth, the nitinol would stress and break down sooner, which would reduce the energy source viability over the lifespan. Cavitation water heaters reduce drag on the components. Powering a cavitation water heater with a nitinol engine reduces the stress on the nitinol itself. It allows for a much less stressful energy transference. A wind generator powering a condenser directly is a stressful transference. More opportunities to break down. All of these factors played into my equation when deciphering the absolute most optimum performance "cradle to cradle," while maintaining the least intermittent form of function. There's millions of scenarios that could work; wind generator tied to a cavitation water heater, hydro to air tank pressure storage, solar electric to cavitation water heater, etc etc etc. But the intermittent issue is always present, as well as the foundry and machining processes added to the energy consumption equation. Cradle to cradle is often never discussed in depth with any energy platform. THAT... is exactly why the oil economy persists, and why people are dumb enough to assume a gallon of gasoline only costs 2 bucks. When the entire system is seen cradle to cradle, almost every energy system falls short of expectations. A nitinol engine (while utilizing geothermal components), powering a cavitation water heater, and utilizing MDI engines for consumption... is the most efficient form of energy usage THAT IS AVAILABLE RIGHT NOW, while also being completely removed from AND non intrusive to the environment as a whole. Cradle to cradle INCLUDES the environment from which the device operates. Wind generators, hydro, solar, etc, all intrude on the environment in some way during AND after their lifespan. Nitinol, and the components of cavitation water heaters, and the MDI engines themselves intrude on the environment, but only during conception (mining). After that, recycling is almost 100% efficient, both in materials and energy implementations.
