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.

Braking can be a simple K.E.R.S. reversed air piston system or air vane system. The actual braking mechanism can be used to resupply air pressure back into the air tank. Imagine that. At every wheel hub, an air vane system that takes the pressure from braking and resupplies it back into the tank.

Mechanical rotational force is what creates air pressure. Specifically, in the way in which I envision a proper off grid system, an ensemble of inputs will create that mechanical rotation. Firstly, using a Tesla turbine from hydro power. Water is essential to survival. Building a dam for an above ground reservoir that sits elevated from the crops the reservoir will water, will create the pressure that spins the turbine. The turbine will be powering an air vane pump, very similar to one of these industrial models...

This is the exact same technology that runs air tools like die grinders, but instead of a pump in that application, it would behave as an engine. The biggest advantage to a rotary vane pump over a piston pump is that the inlet air doesn't require a complex filter system to prevent damage to the piston chamber. "Electricity creating the air pressure" is an admission of not understanding how mechanical energy can be transferred into rotational force.
Second, these pumps will be direct drive units connected to a wind mill shaft to also create the rotational force that spins the rotary vane pump. Consider the inefficiency of using a wind mill to produce electricity by using magnets and copper (inductance). Then pushing that electricity into a purified copper wire system (usually miles away from the end user), just to power a rotary vane air pump or piston air pump motor, just to pressurize an air tank. Albeit, this power source is intermediary and dependent upon the wind. However, there will be an almost 100% conversion of wind power to usable energy, since the system will be directly connected to the wind mill, and the piping that feeds the air tank will itself be useful as an auxiliary tank in and of itself. Wiring between a wind mill and substation is not a battery, but the piping between a rotary vane pump and an air tank is, technically. That's why this type of energy conversion is extremely more efficient than anything electricity can produce... more on this later.

I saw this linked beneath the MDI video. This is the exact same process of storage for compressed air I've explained already. Only difference is the compression system itself. I'd use many different inputs; Tesla turbines, direct air vane compressor systems for wind, solar, etc, ethanol engines, biodiesel engines, and of course, nitinol engines that utilize geothermal for placement, ethanol, biodiesel and pyrolysis from making charcoal for input heat (which very little is necessary), all powering cavitation water heaters that would supply the pressure directly, or indirectly by actuation of Di Pietro engines. The engines would be completely automated with transmissions to supply the air pressure for the bulk storage tanks that would exceed several thousand PSI. I'm going to look through this company's videos to see if there's more in depth examples than just this video, but this was a good example for showing what I've already explained prior. Only difference is the actual inputs for creating the pressure.

There's lots of different kinds of one off custom air compression powered vehicles, but yes. The only air compression vehicles with Di Pietro engines are in his particular vehicles. Here's a few other examples I've seen throughout the years. It should be noted that the engines in all of these are either piston, or air vane motors, though.

Then there's the "overcomplicaters" trying to design pneumatic systems into gasoline or ethanol systems...

So yes, there's lots of different ideas for air powered cars, but what makes the Di Pietro engine so versatile and efficient is that internal bearing system he added between the crankshaft and actuators. That bearing reduces wear and tear tremendously, and allows the engine to run at a much higher RPM before friction causes expansion and potential catastrophic failure. It also allows the engine to run without an oil reservoir, which also reduces drag. Just making an air powered vehicle is quite easy. Almost any engine can be converted to run on compressed air. The Di Pietro engine you're making is the the absolute most efficient and effective air powered engine in existence... that I'm aware of. This is the video that shows exactly why. It's at the 1:30 mark where he shows the internal bearing (I guess you could call it a bushing) barely rotating at all on 1 revolution. It may not seem that significant, but it is when considering the lifespan of the engine. There's barely any friction occurring between components. No other engine has that ability. Even air vane motors drag the fins along the piston wall to create compression. Piston engines drag the rings along the piston wall. All of these setups create friction which leads to a loss of power immediately, create heat that needs lubrication and cooling to mitigate which draws from the potential energy, and wears the parts down over time much faster which creates the potential for lifespan inefficiency.

So yeah, if there was a better air compression system in existence, and I knew about it, that's what I would have suggested. There isn't, though. There's many ways to use compressed air, but you're building the best possible engine currently. If I were to suggest something other than a Di Pietro engine, I'd suggest air vane. They're extremely simple to understand and build. Very few parts. Every air powered tool uses air vane motors as an example. The difference is in efficiency not only during usage, but also longevity. All of this considered and figured into the equation, yes, air powered vehicles are the best overall EROEI, but the general reason for usage changes the dynamic of that equation.

When I mentioned the automated system you're asking about, I was referring to the engines using the steam energy from a nitinol powered cavitation water heater. And yes, those would be Di Pietro engines, and they would more than likely be powering an air vane compressor that would fill massive tanks. The transmission would be automatic because it would be engineered to shift gears as resistance increased or decreased through that cycle. As the tanks become full, PSI increases which creates more resistance on the Di Pietro engine in that configuration. A simple meter measuring the PSI going up would actuate the transmission to shift gears on the Di Pietro engine so it could run at an efficient speed and still produce more pressure. Same thing as going up a hill on a ten speed bike. Hill increases, shift gears. In this case, PSI increases, shift gears. It would be automated through a mechanical device powered by a PSI gauge, though. You wouldn't have to sit there and shift gears as the engines slowed down from resistance. Then, you just gear the system based on the tank's ability. When it's full, the engines would stop all on their own from the resistance alone. Totally automated. All mechanical, no electricity required.
