[@Nirusu87]

The most that could be done to eliminate the friction inside, which is next to nothing, is coat the various inside parts with, for example, a teflon spray or anything similar. However, the inside parts are mainly cushioned and "lubricated" by a thin air film. Source: en wikipedia org/wiki/Angelo_Di_Pietro_(inventor) Yes, the parts make a (minimalistic) connection, however, not as much as that of a conventional car motor, where you'd need oil to keep things rotating smoothly all the time.

[@tedrees5989]

I remember seeing this back in 2006. As you can see there is a prototype car. The Biggest problem is the ASA that the car would have to meet. Then they demand that you put the car through crash tests, even if the chassis and frame have been through these hurdles under a different manufacturer..I believe that the car in the video is a carbon fibre frame which is strong and light. I am sure that sound dampening could be installed to reduce the noise. Also an idea would be to have solar panels as part of the roof and bonnet design for the car. In stall solar panel roof rack. With Batteries. Leave the car in the sun.. great concept. I would very much like to see this car in production. My hat is off to this man.

New carbon fiber composite air pressure tanks can hold 10,000 psi or more and provide a range at highway driving speed, for a large passenger sedan or SUV, of 1000 miles or easily far more (by forming several air pressure tanks into side panel areas) Furthermore, as I've pointed out to GM Cadillac and others, you can use the same technology to make VTOL aircraft, in which case you save huge amounts of weight and increase mpg and efficiency by avoiding wheels, suspension and so forth. This can be made "failsafe" by using gyrocopter rotors that will autorotate in case of any type of failure, to provide a safe landing. (I don't know if counterrotating propellers in Venturi turbo housing can "auto rotate" like this but counterrotating propellers are superefficient and should be used if possible.) Another key consideration is that any auto manufacturer that goes to VTOL aircraft primarily, will dominate the personal and family transportation market.

[@Nirusu87]

I see you might have missed other video's about this concept. The parts will not wear easily since they're not really touching each other when spinning around. Instead, as high pressure was useda thin air cushion between the parts will keep it from wearing out. The lubrication system, is actually the compressed air between the parts

[@rannas6202]

"Competing interests" -- that's the problem!! I share your frustration. Let's make sure to put the link to this video in various chat rooms, social networking etc.

[@antoineraymond4056]

The Di Pietro motor uses a simple cylindrical rotary piston (shaft driver), which rolls, without any friction, inside the cylindrical stator. The space between stator and shaft driver is divided in 6 expansion chambers by pivoting dividers. These dividers follow the motion of the shaft driver as it rolls around the stator wall. The cylindrical shaft driver, forced by the air pressure on its outer wall, moves eccentrically, thereby driving the motor shaft by means of two rolling elements mounted on bearings on the shaft. The rolling motion of the shaft driver inside the stator is cushioned by a thin film of air. Timing and duration of the air inlet and exhaust is governed by a slotted timer, which is mounted on the output shaft and rotates at the same speed as the motor.

[@SolarReadyUK]

[@warriordriver350]

[@coleman4722]

Another seemingly good idea that the hobbyist will never get to use.

[@Nirusu87]

However, I think they've already overcome the inner friction problem. Otherwise the Melbourne Market Authority (which operates a fleet of almost 300 Carriers hired by the market's users to collect and transport their choice of fresh fruit and vegetable produce) surely wouldn't be interested if the engine had any inner deterioration/wear. I'm also sure, the carts being used already travelled many thousands of miles if not tens of thousands. Nonetheless, this development is really worth following

[@hypertuch]

It also has an onboard compressor that will fill the tank in 3hrs for a cost less than $ 2.00 USD for the Hydro and will go 200 klm. that's less than 1 penny a klm, what does your car do for $1;86 maybe 25-30 klm and can you fuel it at home on solar generators. Ohh and this idea was first introduced in 1920 but no car company would pick it up because they were influenced by the Oil industry not to have a car that didn't use Oil

[@BudFactorE]

and I might add they used safety of storing the compressed air an issue back in the 20's but today we have carbon fiber air tanks that wont explode, they crack releasing the air. Which would be better than covering all the victims at a crash scene with gasoline

I guess you could always set up solar to run a compressor during the day to fill a huge air tank , but that costs money and compressors do wear out , it appears there are no silver bullets , the most convenient way to power a vehicle is still a drop of flammable fuel and a well built conventional engine . The things the ice engine has is versatility , the ability to last a long time , ease of manufacture , and the ability to run on a vast amount of different fuels .

Infact: Howcome we have submarines which are powered by nuclear reactors, and we can not have such a reactor power neighbourhoods? Perhaps villages? Perhaps even small cities? Howmany times has such a reactor gone meltdown, like chernobyl (which was just a steam explosion)? And Fukushima? Well, predictable. But let us be honest here. Check Galen Winsor. Howmany times has the reactor onboard a submarine or any other ship that uses it gone into a meltdown or exploded? Exactly.

[@BluntForceTrauma666]

Another clever arrangement of valves/chambers/rotors/shafts/blades/etc. that can extract work from expanding compressed air. The biggest issue I see with this design is the _huge_ amount of friction in the mechanism. I hate to break this to everyone, but in the future, vehicles will NOT be running on compressed air. Compressing a gas to the pressures required to make it worthwhile isn't efficient AT ALL. The volume of compressed gas (air) required to give a vehicle a reasonable range is *enormous.* BTW, getting a patent for an idea or "invention" doesn't really mean shit unless it's a GOOD idea and someone else tries to duplicate it within their own product. Being the owner of a patent simply means you were the _first_ person to legally document an idea. It could be the dumbest thing in the world, such as a solar powered fart sequestering blower - as long as you're the first person to have it legally documented, you get a patent #.

In many scientific magazines the efficiency of air engiens is critizised harshly. But in those articles the fact is completly neglected, that we have a lot of surplus regenerative energy from sun and wind, which we are not able to store efficiently. If we would use the unused energy from sun and wind to compress air, the air engines would seem much more efficient when calculating in the zero-cost energy that we completely waste by now.
