Massive Yet Tiny

[TMKSilenced]

I think the person was referring to frictional losses, a larger diameter pipe or tube will incur less pressure drop when you have a viscous fluid flowing through it at the same initial pressure (Air is a viscous fluid) key word, durring flow and at the same initial pressure at the starting point. As to how he was trying to relate that to the conversation, I don't know.

[HybridWaterMan2]

I love this design, but it seems the only thing I have ever seen is it being run on compressed air. Has it ever been tested as a combustion engine or are there any videos showing that?

[hardkoren]

@HybridWaterMan2 It has been run on a fuel (diesel? gasoline? not sure), but if there's any problem, it blows up and they have a hard time figuring out what went wrong. If there's a failure with compressed air, its much easier to figure out what went wrong. They don't have the cash to be blowing up engines.

@HybridWaterMan2 , Go to Angel Labs

[minitrucka4life]

wtf is this thing?

[wtfowns]

texmurphy51 please research what you say before you say it. As far as your garden hose (hydraulics) comment look up Pascals principle. For your pneumatics comment, look up Bernoullis principle and a good dose of fluid dynamics for both. also look up circuit basics. Wire size is determined by amperage, not voltage. A wire can handle many KV's with very low current. Please educate yourself before confusing yourself and everyone else on the internet.

[NearAbbeyRoad]

I believe this engine has not run powered by fuel yet. Is that the case?

The concept is very good and a great step up. I see the best applications in static and vehicle mounted genny sets.

[silverbird58]

The worst speech in the worlds starts out as " i can't believe" . i dont beilve in etheric energy , since i cannot find a meter or other measuring devise . but this dont mean it's not there.

[ptairco]

I can't believe NASA dignified this nonsensical contraption. If it put out the power advertised, it would melt own - where would the heat from that much power go?? Talk to us when you have a running prototype, nit just a collection of parts whizzing around under compressed air.

[NearAbbeyRoad]

@ptairco

The more efficient the engine the less heat it produces. The fuel energy is converted to turning motion - HP.

The less efficient, generally the more heat produced. A small reciprocating piston IC engine can heat a cars interior in Arctic conditions, so much heat is produced by the engine. And that is not capturing the heat from the exhaust. In fact heat is its main output, not turning motion.

[Superman83271]

@ptairco He's using his fuel to turn the crank. This thing won't put out anywhere near the heat of an equivalent conventional IC engine.

[Texmurphy51]

Can you imagine how much this guy has invested in this display? Maybe he should have just built a one piston working model?? This thing would simply melt because it cannot dissipate the heat it generates.

[silverbird58]

maybe it can

[silverbird58]

if the pistion moves easy less heat is needed to move it (break inertia) . my diesel never gets hot hell all i haul is dog and sack of groceries. now under load it might but i say with agood squirel cage around it no problem for years i couldnt understand why the 1/2" dia. cox airplane motor didnt melt away , same heat tranfer

----to power weight ratio aplies here..

[Texmurphy51]

The heat is not from friction but burning fuel. Engines are kept cool by transfer of heat to oil and other to water jacket. The third is to run a richer fuel mixture, thats how the cox motor kept cool, (also type of fuel). Did you ever feel the heat coming off a car in the summer.  That same amount for the horsepower would have to coming out of this motor, somehow. It might be able to produce high HP for short periods but would melt down quickly. PS this design has been around a long time.

[silverbird58]

@Texmurphy51 how come my diesel in my small tractor doesnt overheat it has iron block runs slow . and a 18"sq radiator , well it will break 160 deg if i mow plow hard and work it but thats all i still say he has found a better way to use soybean oil. i agree since he is doing the work of a 850 cu , his (at temp)

operating frictionwill need to be the inverse mathmatically of the 475 cummins to prefome as he says. If the alloys are there who cares if it runs

at 350 deg. .

[Texmurphy51]

It radiates its heat from the block and the small radiator. Your not making 300hp with it either. Ideally the best efficiency would be to run a hot block , insulation around the block, no radiator only heat comes out the exhaust but no materials or lubricans can take that. If the heat is not dissipated the pistons will melt and thats what it boils down to.

[silverbird58]

@Texmurphy51 may not 300 hp .but the

torque one would think would be high

due to themechanical advantantage. If this machine will withstand 70 comp under full heat load it will sell. gotta be tough alloy,

[Texmurphy51]

You know that there have been losts of similar engines to this starting in the 50s. Otto Lutz built one in WWII Germany. Rotoblock looks the same as MYT and Roundengine is a lot simpler and might actually work.

[juggernautxtr]

@Texmurphy51

actually thats where this guy got his idea. only he played with it to get his design. he readily admits where he got the idea.

[Texmurphy51]

Guys built working prototypes of engines in the late 1800s dispite crude materials & tools. You would think this guy could build a small working model instead of one for show. Biggest problem is this will not be any more efficient than a regular engine, only smaller.

[juggernautxtr]

well thats the problem with any prototype thing, it may work, just doesn't have the money to keep making them. i watched a different video where that same motor made 800 hp on compressed air.If it can handle that much air pressure going through it it is quite feasible it could stand the ignition of gasoline in it too. all you would have to do is put a plug where the air inlet is. it already has exhaust and inlet ports.

[Texmurphy51]

No I think it would melt. Thats the flaw in this design. Your concentrating all the heat of a normal engine into a smaller space. You got to get rid of that heat. His design is no more efficient than other engines, just smaller. Small prototypes do not take much money. If he gets a good machinest onboard they could make anything.

[juggernautxtr]

metals have come a long way, till i see a regular gas prototype. i ain't gonna deny the guy a smart invention, till somebody proves it wrong and not working like he says. but if it works and holds up i will be the first inline to buy. the thing is obvisuosly well ballanced if it can spin with 800 hp. of air pressure.

[Texmurphy51]

The japs worked on a hot block engine using ceramic but the problem is lubricants at high temp. Regular fuels wont work either. You dont need to make a 800hp full blown prototype, that would be stupid. You make a small lab model to test & modify. At 120psi 200hp of compressed air takes a 4 inch pipe. He ran 800hp of air thru a 2" pipe? There are no details on the demo on pressure, flow. I doubt if it produced 800hp on compressed air thorugh those small openings.

[juggernautxtr]

the size of the pipe would not effect the pressure only the volume.

he might have built this not knowing the horse power he could get out of it.

[Texmurphy51]

The size of the pipe effects the pressure & volume. A tiny pipe will flow a set volume with a large drop in pressure where a large pipe with have a little drop in pressure. I have designed Pneumatic systems & you simply look it up on a chart. Flow, Volume, Distance, Pressure Drop. At 100psi it would take 4800SCFM of air to create 800HP. The Video is unclear but I dont think you could flow that through those hoses so the pressure would have to be much higher which brings new problems.

[juggernautxtr]

size to pipe does not effect pressure go back to school 800 psi running throiugh a half inch pipe is the same as 800 psi running through a 2 inch pipe, it only effects volume.

[Texmurphy51]

It effects the pressure AT THE POINT OF USE.  Run a garden hose to your sprinkler & if you measure the pressure at the sprinkler it will be just slightly below line pressure. Now replace that with a 1/8 in line and then measure the pressure. The sprinkler will be spitting a little water & the pressure will be almost nothing. Line size changes Volume & Pressure at the point of use. Thats the point because Volume & pressure determine how much ENERGY is at point of use.

[juggernautxtr]

the pressure is not released like a garden hose the pressure is not released till a certain position put your finger over the end of the garden hose. the pressure in most homes is 35-45 psi youy will get 35-45 psi build up.

[Texmurphy51]

The point is that the smaller you make a hose or pipe to a device, the lower the Volume and Pressure will be at the device. We are not talking about your finger since its not a constant load. Of course if you close the end of the hose it will build up pressure. When you USE water it will drop. Smaller pipe means lower volume & pressure at the point of use. The same applies for electricity. Smaller wire means less amperage & lower voltage at the point of use.

[juggernautxtr]

engines work in a similar way. the valves are your finger.

an engine is nothing more than an air pump.

[Texmurphy51]

Well theres more than one valve(finger), as one finger closes the other opens. So in effect the finger is open all the time, one piston valve closes the other opens. This drops the pressure in the hose as the volume increases. The smaller the hose the more the pressure drop. Try it, take a hose, put a valve & pressure gauge on the end, open the valve slowly & you will see the pressure drop. A bigger hose will have less pressure drop using the same valve. Hose size limits the flow.

[silverbird58]

yea tex i agree , also the inverse (overall ) is true too if you increase your pwer brake booster hose dia. or lenth .. the vaccum is still the same .. yet the EFFECT on the booster diaphram has lessend eventhough your vacuum gage says its high and steady.. perhapse this is simmular..

[Texmurphy51]

@silverbird58 It is similar. The point is that pressure & volume are different at the other end of a hose, depending on its diameter. A larger the hose is, the better it can maintain the pressure using more volume. Extreme example - lets say you run a 1/4 inch hose to your hose from the street. As soon as you turn on the water the pressure will drop to almost nothing. Now run a 1 inch & pressure will be close to that at the main. Supply pressure is always the same, end of the hose changes.

[TMKSilenced]

The pressure in most homes is not 35-45 psi. 45 psi is over 3 atmospheres. Most homes dont cycle in outside air so they are generally at atmospheric pressure but lets say you have a window unit, then yeah, slightly higher. by maybe 1-2 psi... if that. Commercial buildings have air quality codes (HVAC) to meet which require them to cycle in outside air. some rooms hold at higher pressure than others depending on quality requirements for a given room. but 16-19 psi is the most you'll see.

[juggernautxtr]

@TMKSilenced that wasn't a referance to air pressure......... we were talking about a garden hose... what garden hose are you proposing air conditions a home? christ I am tired of people that think they know something then make complete asses of them selves running their mouth.

[Superman83271]

@juggernautxtr HOWEVER 800 psi pushing on a large area and 800 psi pushing on a tiny area are way different in gross pressure. If you exploded a 1/2 inch pipe under 800 psi you would get a loud explosion and some shrapnel. Explode a 24 inch pipe under 800 psi and you could remove a large building. Smaller pipes of a given tensile strength material will hold more psi than larger pipes of the same tensile strength, because with the smaller pipe there are fewer si for the p to act on.

[juggernautxtr]

@Superman83271 again you are confusing volume with pressure, you can not change pressure you can only change volume.

[silverbird58]

i agree ,and since he could statically put the comp ratio almost whereevery he needs it  lets think he can move the power band and heat where its most needed maybe?

[juggernautxtr]

@silverbird58 well considering what his theory of the engine is it would be a torque monster. and would considerably decrease the size of engines as we know them to be so where he sets the compression,timing, volume of air and fuel to be compressed, will determine what it would do and the size of the engine and if it would need to be rpm limited. the nice thing is that there would be no head gaskets to blow. the only thing i would be concerned about is oiling,cooling.

[coldkeith]

I can't tell where the jealousy ends and the ignorance begin., Why was this technology chosen by a panel of scientists and engineers at NASA but it's not good enough for you (uh, who are you?)? This is a Torroidal engine, it's a very old design, the issue (back then) was valve timing. There are videos of it running, you should be helping these guys - unless of course you work for the other (oil) side. Read up!

[seansalvador1]

The point is that this engine cannot produce more energy than conventional ones.

[coldkeith]

According to...

[seansalvador1]

Rather exess energy.

[juggernautxtr]

it's not creating excess energy it is using the energy produced more wisely.

[seansalvador1]

Ah... i see i was answering the wrong commen t to start off with. Sorry.

[Texmurphy51]

That NASA award was in 2005. Morgado was someone to invest 10mill to make a production facility when he has NO working prototype. Never going to happen. I think he is just milking investors for more money. There are plenty of investors who would put the money up if this could actually work. He is looking for dumb investors. I worked for an inventor with a carb in the 70s who did this. Do tests, get investors, keep them on the string by saying you are close but need more money, time.

[Geezertron]

WowI I can feel the uber-efficiency of this bad-boy vibrating in my speakers! My speakers are only 20 watts, but there is clearly 30 watts coming from them while this video is playing! Where can I send a blank signed cheque?

[30GB]

massive yet shit i seen it its so crappy it has a tiny shaft that can break like a tooth pic and they never had a real test on it yet only on air

[silverbird58]

hey you sound unamerican . leave here

[juggernautxtr]

another ignorant dumb shit who didn't listen he had it running on bio fuel.

and don't buy a rotary then it's smaller than a normal crank.

[robwe359]

The inventor of this has resurfaced after two years of silence. Last I heard he is about to set up manifacturing for this engine, or at least some further development of it.

[importsstillsuck]

lol almost looks like they have valve reliefs

[abram730]

Stirling engines

[bloodreighn]

Stirling? no.. that was a cut away MYT Rotary piston engine

[claypunk]

Very Impressive.

[grant9908]

I'm going to send this link to my dad.....

[Amechurr]

was tht a blender??

[stopcheating]

is that a stirling engine?

[file83]

LOL - it's a hybrid between the perpetual motion machine and a stirling engine.  You can get 7000+ miles per gallon!

[stopcheating]

Stirling engines exist... The segway guy builds them...

[corotor12345]

who told you that? its no hybrid between that nonsense of yours... and it has nothing to do with the stirling concept since it SUCKs air... stirlings have an internal working fluid... no leaks no nothing... so shut up please and just watch thte vids from now on

[OGEZZE]

WHAT THE HELL KIND OF MOTOR IS THIS?
