its a lot easier to silence a constant pitch at a constant volume at a high frequency than it is to kill the low frequency and transients... it sounds awful, but with a bit of pipe and some strategically located holes/slots, this would be nearly inaudible. as a box like this, its fine, as something a bit more permanent, an auxillary muffler can be too. its just like making a flute... in reverse! play it the same pitch and they cancel.
Thanks so very much for sharing that with us! I’m an aircraft mechanic and have a lot of experience working with turbine engines and I didn’t know that they made small gas turbine generators for home use.
Hello from Japan. Exciting to know you are the cool aircraft mechanic. I am a aircraft fan, especially about the powerful gas turbine . IHI produced this portable gas turbine about 15 years ago. Even though they are still researching the new generation portable gas turbine for home use, but, it is still a long time before they launch it for market. Nice to know you, man.
They used full size turbine generators in AT&T central offices or switches .. the fuel consumption was excessive along with the noise, so they installed them on the roof penthouse with relatively small footprint … problem was only having a small day tank ( fuel) and the main tank in basement fuel delivery was an issue and not practical
For those commenting on the noise: Sound level 55 dB(A) 50 dB(A) Light traffic, Refrigerator 46-70 dB, Average. One-fourth as loud as 70 dB. 60dB(A) Conversational speech, Air conditioner Half as loud as 70 dB. Fairly quiet Engine Single-shaft regenerative gas turbine Generator type Permanent magnet system Rated rpm 100 000 rpm Rated power 100 V Rated output 2.6 kVA Frequency 50/60 Hz (can be switched to either frequency) Fuel used Kerosene Fuel consumption rate Less than 4.5 l/h (at rated output) Operating temperature range -20°C to 50°C *Sound level 55 dB(A)* Dimensions 825 (L) × 420 (W) × 455 (H) mm Dry mass 67 kg
The pitch is an issue, too, though. 55 db at a high pitch is less bearable than 55 at the pitch of a human voice. Imo. edit... I have been informed that the (A) means that the noise level has been weighted to account for the perceived effect of pitch differences. So, basically, my comment is pretty much meaningless as a response to the original comment. However, in true internet fashion, I still think I'm right, obviously. I ain't gunna let no facts get in the way of my ignorant convictions, ya'hear!

Wow that sounds exactly like a 14 inch turbomolecular pump or small jet engine firing up. You should be able to run it on almost any fuel once it starts up too.
This is really cool, and might try to make one of these myself for kicks and giggles, but is this not ridiculously inefficient?

@paradiselost9946 peak temperatures certainly do limit efficiency in gas turbines, but pressure ratio is actually very high in large turbine engines - that's only an efficiency issue for small and simple gas turbines... like the little thing in this generator set. I agree that clearances are also a problem in small sizes.
That's what I thought, generators don't forgive poor maintenance, especially Honda... so the longer between intervals, the less likely this will happen.
It's not exactly quiet, but piston engine generators are much louder. One of the great things about gas turbines is much less friction compared with piston engines and no loss of energy from reciprocating parts.
That's not exactly true. Gas turbines are less efficient when operating at low or a wide range of rpms. When operating steadily at high rpms they are considerably more efficient than piston engines. For instance, they are used in most powerplant peaking plants. They do not lose energy from the reciprocating motion of pistons and they do not have the friction of the piston rings and other components of an internal combustion engine. In an application such as this generator they could well be more efficient than a piston engine. @@sompka1
@@brodricj3023 yes, those small inverter ones. But a 30 amp, 120 volt RV generator can be heard at distance....and felt in the RV. This thing would be perfect. Nice and smooth and no vibration. Would be like riding in an airplane but a lot quieter and with no turbulence. Literally no information about it from the manufacturer and it doesn't look like many were produced. I want one though lol
This must be older tech. They have a model out on the market now from another company that is able to be carried by hand and turbine powered. It can produce 10kw at full throttle.
Actually? No, not an after burner. When you load these gas turbine generators, they spool up like that, the first level was idle. When it went up in rpm's, it was coming up to full speed so when the contactor kicked in (to connect the generator to the load) the generator would be at operating voltage and ready for whatever load you apply. This itty-bitty works very similar to the bigger ground power units I've used to get an aircraft ready to go. Would I like to have one? You betcha.
Considering that we could here you operating a switch on the generator while it was running, this is incredibly quiet for any modern engine and u believably quiet for a turbine.
Modern technology can be used to farm methane with your kitchen waste and lawn waste in two one cubic meter plastic containers. You can compress those methane fully automated into a light-weight, installable propane tanks for charging your Aptera in the backyard 7/24. If you don't use them to charge your Aptera, you can use them to cook your food or warm your house as well. All kitchen waste will become fertilizers eventually, which you can sell/donate to vertical/roof-top organic farms around metropolitans.
Kerosene oil fuel means it can be operated on Light Heating Oil which is essentially identical to Diesel fuel right? Its very cheap in my country around 1€ per Liter.
Kerosene comes basically in two flavors. The Jet fuel for planes and kerosene which has a lower flash point that you can buy at the automobile gas stations. Which one this device uses I am not sure.
It would run on diesel. Might produce a wee bit more soot, and getting it going would be difficult in very cold weather like 40 below, but it would run on diesel fuel.
How does the cost and fuel consumption of this compare with a reciprocating (gasoline or diesel) generator? Turbine units like these seem to be a small niche, in general turbines are better in power-per-weight, lifespan, and maintenance but worse in fuel consumption and price. One application for something like this I could see would be as a range-extender or series hybrid system in an electric car or even aircraft, where it would be running at constant speed and power, run at it's optimal efficiency to charge the batteries, and size and weight are important.
You would need a really powerful electric motor combined with a battery pack capable of being charged rapidly to make full use of a gas turbine engine running at optimal efficiency. That term gets thrown around a lot, and few people understand what it really means when applied to gas turbine engines. Basically, anything you understand about piston engines should be completely disregarded when it comes to turbines - there is hardly anything you can compare between the two, except that the fuels they use can sometimes be similar. While it's true that the peak efficiency of a piston engine (whether petrol or diesel) is somewhere between 60% and 70% of maximum rated power, the same is certainly not true for gas turbines. In fact, the only way to get maximum efficiency out of a gas turbine engine is to run it at 100% for as long as possible - anything less and you are essentially burning fuel just to keep the engine turning over but producing nothing useful. To give you some perspective on how true that is, ask yourself this: What is the difference in percentage of maximum RPM between full power and flight idle for any gas turbine aircraft engine? Doesn't matter whether we're talking about turbojet, turbofan, turboprop or turboshaft, because the core part of all of them is the same - compressor, combustors and turbine to power the compressor, with any excess power either being accelerated out of a jet nozzle for thrust or directed through a power turbine to spin something. In any case, the answer is about 15% at most. Yes, flight idle is considered about 85% of maximum rpm, with ground idle only a few percent lower than that. In a power station, where you have a gas turbine core with a thumping great power turbine bolted to the back, using an LM2500 for example, some 90% of the power output comes from the last 10% of core RPM. In power stations using gas turbines, they regularly run the cores at 100% of rated RPM for months or years at a time, only slowing or stopping them if there's a maintenance issue to deal with. You would be correct that connecting the gas turbine engine to an electrical generator (driven by a free power turbine) would be the most efficient way of using the power output. But only if the equipment you are running (electric motors, battery chargers or a combination of both) is capable of using the power output of the gas turbine when running at 100% for as long as possible. So for an electric car, the electric motors would need to be capable of using every bit of power the gas turbine generator could make. Which would only be necessary at maximum acceleration, so you would need a battery bank and charger capable of absorbing any surplus power that the electric motors are not using, in order to ensure that the gas turbine can stay at 100% even when the motors don't need all of it. Then of course once the batteries are fully charged, you would need to shut the gas turbine down and run on battery-electric mode only, otherwise you would end up wasting power.
What is the fuel consumption at full and half load? My dogs went nuts when I watched on the computer speakers. Even if its quieter than a reciprocating engine, that whine is going to be irrirtating.
You never put a load on it...? Running at "idle" is great, but not a valid demonstration at all. What's it do, how does it perform, when loaded-up to 50-80%?
that's a really small capacity... our littlr honda is rated at 2800, and there are many cheap tri fuel 13kw units. what kind of fuel does this use and how efficient is it? for constant load I am guessing this is great, but maybe not for variable load?
Officially it burns kerosene but apparently diesel is acceptable too. There might be a maintenance penalty however. 2.6 KW is the maximum load at which point it consumes 4.5 L/hr
I am still waiting for the gas generator that is silent, close to dead silent, producing from 100 W up to 1 kW, depending on load. Yes, must be small also. Handbag size.
@@leechjim8023 Legit I want a 20KW uSMR (micro-Small Modular Reactor....copywrite, trademark, do not steal, OG head canon) installed under my driveway. But the stupid nuclear regulatory commission wont let me.......because apparently it makes the NSA nervous. I keep shouting into my cell phone randomly if they're not planning on raiding me they have nothing to worry about, but they still wont let them let me have one... 🤬
How about batteries with inverter and solar panels? That is how I do it in my camper van instead of using a generator... I have 5000w/h of Life-po4 and 3000w inverter with 1280w of solar panels. And if I run out of power I can start the engine of the car to charge the battery bank also. Portable battery bank with built in inverter is pretty much silent (if not the cooling fan for the inverter starts). And they can be connected to portable solar panels for charging. Other then that you have fuel cells that use methanol to create electricity but they are horrible expensive and give little power.

@@yes-man1112 Wow - I thought this would make a great range extender for electric vehicles - but at that rate of fuel consumption and 2.6KW output - any charge produced would make the car have an efficiency of 6 mpg or 39.2 l/100km. This is truly eye opening (and still totally cool). If only thermoelectric generators could take advantage of the exhaust temperature (unfortunately they're even less efficient). Look up Hyliion's Karno linear generator ... it's very interesting. It uses flameless ignition in a Carnot cycle - it's is fuel agnostic (would even run from the heat of spent nuclear fuel).
Back in the 70s and 80s, the German Manufacturerer Junkers made a Stationary Turbine for MAchines like Waterpumps, Generators and so on. Machines like that were also Made in the GDR and in Great Britain. Not so very common, but they were sold and you could buy one of these.
Here in the uk they have started using small automated gas turbine generators situated on industrial estates to boost the local grid all the noise is directed up so you cant hear them at ground level .
I saw the switch for 50/60 hz on there, but it looks like the output is 100V. In the US, we'd need 120 V. Is that what the other switch is for? (at the top left)? I am also wondering if there is a split phase / 240 V option? This is really neat, thanks!
@@Melanie16040 wow, I never realized that. How the heck does that work? So many things that are built to run on AC are highly dependent on the frequency, way more so than the voltage. I'm thinking of clocks and motors in particular, but I can imagine just about anything that doesn't first rectify the current to DC.
i would be absolutely stunned if the waste heat from the exhaust also went to heating water, even if it was an optional extra... i dare say its EGT at the outlet is still well over 100C. seems a shame to waste it...
It more than likely _could._ But I wouldn't. I used to work on Huey helicopters and you could use diesel as fuel in emergencies (as opposed to jet fuel)... but only for limited amount of hours, and then the engine had to be inspected. It burns at a different temperature which can stuff the turbines and or other components.

That's what I thought, generators don't forgive poor maintenance, especially Honda... so the longer between intervals, the less likely this will happen.
does it use heat regenerators recovery wheels like the chrysler turbine in the 60's?
It's not exactly quiet, but piston engine generators are much louder. One of the great things about gas turbines is much less friction compared with piston engines and no loss of energy from reciprocating parts.
Huh? You can hardly hear a Honda 4-stroke generator.
Much lower efficiency. They have much higher power to weight ratio though.
That's not exactly true. Gas turbines are less efficient when operating at low or a wide range of rpms. When operating steadily at high rpms they are considerably more efficient than piston engines. For instance, they are used in most powerplant peaking plants. They do not lose energy from the reciprocating motion of pistons and they do not have the friction of the piston rings and other components of an internal combustion engine. In an application such as this generator they could well be more efficient than a piston engine. @@sompka1
@@brodricj3023 yes, those small inverter ones. But a 30 amp, 120 volt RV generator can be heard at distance....and felt in the RV. This thing would be perfect. Nice and smooth and no vibration. Would be like riding in an airplane but a lot quieter and with no turbulence. Literally no information about it from the manufacturer and it doesn't look like many were produced. I want one though lol
Interesting receptacles on that thing. I've never seen those before.
This unique unit looks like it was getting ready to launch 🚀 and fire out some afterburners .🚀Awesome operation !🤙😉
This's the household version of an APU!
Yes, exactly !
Sort of, but given the definition, you could actually have a regular piston-engine generator as one.
Yes! An expensive apu!
Awesome machine. Thanks for sharing it.
Thanks for posting a demo video for one of these things. I've wanted one ever since I found out about 'em.
What great sound characteristics!
I almost couldn't even hear it over the jet airplane in the background.
Fantastic way to get the camping site all to yourself
5L per 2.6kw/h. No wonder why no one buys it
yep. and turbines usually expensive also. in USa there were more powerful versions also used as a portable high power pump
This must be older tech. They have a model out on the market now from another company that is able to be carried by hand and turbine powered. It can produce 10kw at full throttle.
Interesting generator. But 100 volts, must be for the region in Japan that still uses 100 volt system.
not a big problem could be make for 120 or 110
Perhaps you are thinking of the 50 - 60 Hz schism?
I like when you flipped the afterburner on 👍
Actually? No, not an after burner. When you load these gas turbine generators, they spool up like that, the first level was idle. When it went up in rpm's, it was coming up to full speed so when the contactor kicked in (to connect the generator to the load) the generator would be at operating voltage and ready for whatever load you apply. This itty-bitty works very similar to the bigger ground power units I've used to get an aircraft ready to go. Would I like to have one? You betcha.
That sucker about to take off
Considering that we could here you operating a switch on the generator while it was running, this is incredibly quiet for any modern engine and u believably quiet for a turbine.
Hi, could you please mention the level of db(decibel) of this turbine,
I just referred the manual doc, It was
Wow home APU just like in the big commercial aircraft. Do they sell these in US?
I like the remote start, dual fuel, and it is easy to move around. Great for the RV!
Interesting fact gas turbine can run on any liquid or gas that will burn ,if 1) will flow through filters 2) flow through injector
Wow I have never seen a gas turbine generator before. Cool!
The neighbors are going to love my new purchase
I’ll only test it 3 times a week
Sound level 55 dB(A)
50 dB(A) Light traffic, Refrigerator 46-70 dB, Average. One-fourth as loud as 70 dB.
60dB(A) Conversational speech, Air conditioner Half as loud as 70 dB. Fairly quiet
Interesting concept, I have a gas inverter generator, same power and half the size. (quiet and a whole lot lighter) What's it's fuel efficiency?
I bet your neighbors really love you.
and their dog
When does it take off?
Can you vacuum the floors at the same time?
Haha yes
Imagine starting that up on a campsite, late at night.
They will call Fox Molder immidiately-and scully to solve the "mistery"
Modern technology can be used to farm methane with your kitchen waste and lawn waste in two one cubic meter plastic containers. You can compress those methane fully automated into a light-weight, installable propane tanks for charging your Aptera in the backyard 7/24. If you don't use them to charge your Aptera, you can use them to cook your food or warm your house as well. All kitchen waste will become fertilizers eventually, which you can sell/donate to vertical/roof-top organic farms around metropolitans.
Kerosene oil fuel means it can be operated on Light Heating Oil which is essentially identical to Diesel fuel right? Its very cheap in my country around 1€ per Liter.
Kerosene comes basically in two flavors. The Jet fuel for planes and kerosene which has a lower flash point that you can buy at the automobile gas stations. Which one this device uses I am not sure.
It would run on diesel. Might produce a wee bit more soot, and getting it going would be difficult in very cold weather like 40 below, but it would run on diesel fuel.
What is the big advantage of these thing compared to piston driven generators?
none--they are 100 percent useless
The HOA is gonna love this one!!
When are they available in the backward west 😮
Quiet operation. Yup we have a very distinct idea on quiet...
Afterburner included?
Wish they produced these still
Yes, I spent almost 3years to find this machine around the world using internet， and fortunately,
I was so Lucy that I got it in this April
A beautiful machine, with such a high tech siren’s song! I am in love.
I want my car to sound like that!
F..ng excellent 👍 Just love the control panel, it’s like starting up an old Lockheed Jetstar.
How does the cost and fuel consumption of this compare with a reciprocating (gasoline or diesel) generator? Turbine units like these seem to be a small niche, in general turbines are better in power-per-weight, lifespan, and maintenance but worse in fuel consumption and price. One application for something like this I could see would be as a range-extender or series hybrid system in an electric car or even aircraft, where it would be running at constant speed and power, run at it's optimal efficiency to charge the batteries, and size and weight are important.
My first thought was: That thing is going to suck a LOT of fuel.
You would need a really powerful electric motor combined with a battery pack capable of being charged rapidly to make full use of a gas turbine engine running at optimal efficiency. That term gets thrown around a lot, and few people understand what it really means when applied to gas turbine engines. Basically, anything you understand about piston engines should be completely disregarded when it comes to turbines - there is hardly anything you can compare between the two, except that the fuels they use can sometimes be similar. While it's true that the peak efficiency of a piston engine (whether petrol or diesel) is somewhere between 60% and 70% of maximum rated power, the same is certainly not true for gas turbines. In fact, the only way to get maximum efficiency out of a gas turbine engine is to run it at 100% for as long as possible - anything less and you are essentially burning fuel just to keep the engine turning over but producing nothing useful.
To give you some perspective on how true that is, ask yourself this: What is the difference in percentage of maximum RPM between full power and flight idle for any gas turbine aircraft engine? Doesn't matter whether we're talking about turbojet, turbofan, turboprop or turboshaft, because the core part of all of them is the same - compressor, combustors and turbine to power the compressor, with any excess power either being accelerated out of a jet nozzle for thrust or directed through a power turbine to spin something. In any case, the answer is about 15% at most. Yes, flight idle is considered about 85% of maximum rpm, with ground idle only a few percent lower than that. In a power station, where you have a gas turbine core with a thumping great power turbine bolted to the back, using an LM2500 for example, some 90% of the power output comes from the last 10% of core RPM.
In power stations using gas turbines, they regularly run the cores at 100% of rated RPM for months or years at a time, only slowing or stopping them if there's a maintenance issue to deal with. You would be correct that connecting the gas turbine engine to an electrical generator (driven by a free power turbine) would be the most efficient way of using the power output. But only if the equipment you are running (electric motors, battery chargers or a combination of both) is capable of using the power output of the gas turbine when running at 100% for as long as possible. So for an electric car, the electric motors would need to be capable of using every bit of power the gas turbine generator could make. Which would only be necessary at maximum acceleration, so you would need a battery bank and charger capable of absorbing any surplus power that the electric motors are not using, in order to ensure that the gas turbine can stay at 100% even when the motors don't need all of it. Then of course once the batteries are fully charged, you would need to shut the gas turbine down and run on battery-electric mode only, otherwise you would end up wasting power.
What is the fuel consumption at full and half load? My dogs went nuts when I watched on the computer speakers. Even if its quieter than a reciprocating engine, that whine is going to be irrirtating.
This is really awesome I wish every family on the Block had a dynajet 26
Thank you for sharing this video.
Now I know another thing that I don't want within a half mile of my house.
You never put a load on it...?
Running at "idle" is great, but not a valid demonstration at all. What's it do, how does it perform, when loaded-up to 50-80%?
Wow. That's a sexy unit!
Congratulations on 1k likes 🎉
Legit fighter jet noise generator. 😂
What’s with all the pointing?
Bet the neighbours love it
Where can I get one? That’s awesome
Is it made in China? Looks like the square bracket in the left is starting to rust.
I don't suppose we'll be seeing these in the U.S. market anytime soon with standard 120/240v 60 cycle AC output?
I’ve seen this thing around for years, I always seem to miss it on auction. Someday I’ll have one!
That high pitch is extremely annoying but I do like the cool factor
Is this an aircraft APU in a box?
I wish I could get a little turbine instead of an air-cooled V-twin to power my home standby generator!
Nice, especially the turbine sound is too coooool
It’s so whisper quiet. is it running? I can’t tell.
Was waiting to hear the rotors engage and start to spin
that's a really small capacity... our littlr honda is rated at 2800, and there are many cheap tri fuel 13kw units.
what kind of fuel does this use and how efficient is it? for constant load I am guessing this is great, but maybe not for variable load?
Officially it burns kerosene but apparently diesel is acceptable too. There might be a maintenance penalty however. 2.6 KW is the maximum load at which point it consumes 4.5 L/hr
If it has a E A R what is it made from?
I am still waiting for the gas generator that is silent, close to dead silent, producing from 100 W up to 1 kW, depending on load. Yes, must be small also. Handbag size.
And I want a pony....
How about nuclear!🤪
@@leechjim8023 Legit I want a 20KW uSMR (micro-Small Modular Reactor....copywrite, trademark, do not steal, OG head canon) installed under my driveway.
But the stupid nuclear regulatory commission wont let me.......because apparently it makes the NSA nervous. I keep shouting into my cell phone randomly if they're not planning on raiding me they have nothing to worry about, but they still wont let them let me have one... 🤬
How about batteries with inverter and solar panels? That is how I do it in my camper van instead of using a generator... I have 5000w/h of Life-po4 and 3000w inverter with 1280w of solar panels. And if I run out of power I can start the engine of the car to charge the battery bank also.
Portable battery bank with built in inverter is pretty much silent (if not the cooling fan for the inverter starts). And they can be connected to portable solar panels for charging. Other then that you have fuel cells that use methanol to create electricity but they are horrible expensive and give little power.
@@a64738 Thanks for your kind suggestions. Eh, I am fantasizing about something where I don't have a car engine running. When I say fantasizing, because I am aware that what I wish, is not going to be made, as far as I would recon. ... Thank you for your support and suggestions.
with the amount of small turbines now available why aren't these in all the shops?
Do you have any turbine generators that are large and efficient?
Thanks for your comment. I’m very sorry I just collect several this type MGTs. I’m also willing to get one bigger gas turbine as my toy 😀
Is that a joke
@@kalacaptain4818 A guy in England has his own Rolls Royce RB 211-524 series gas turbine from a 747. There's a TH-cam video of it starting up in his garden.

Fantastic the whisper quiet model
Where can I get one ?
Japan. Apparently, the one seen in the video only produces AC voltage specific to Japan, though you could switch the output between 50HZ and 60Hz, depending on where in Japan you'd want to use it.
Fantastic, what a magnificent machine, gets 1.5 liters to the Volt and turns in 196.583 amps per fart, guarantees ultimate satisfaction and creats a Hyperspace loop that wastes one incoming power dernal from the ether,,, I loved the specs :) cos that's why I watched it!!!!!!!!!!!!!!
2.6 KW…how much fuel per hour? (or per minute?)
Thanks for your comment. The fuel rate of this gas turbine is about 5L/hour
@@yes-man1112 Wow - I thought this would make a great range extender for electric vehicles - but at that rate of fuel consumption and 2.6KW output - any charge produced would make the car have an efficiency of 6 mpg or 39.2 l/100km. This is truly eye opening (and still totally cool). If only thermoelectric generators could take advantage of the exhaust temperature (unfortunately they're even less efficient). Look up Hyliion's Karno linear generator ... it's very interesting. It uses flameless ignition in a Carnot cycle - it's is fuel agnostic (would even run from the heat of spent nuclear fuel).
@@ivantuma7969 Depleated uranium?
How would a person dampen that noise?
How much power it can produce in an hour and what is the fuel consumption?
Neighbors will love that thing.
Back in the 70s and 80s, the German Manufacturerer Junkers made a Stationary Turbine for MAchines like Waterpumps, Generators and so on. Machines like that were also Made in the GDR and in Great Britain. Not so very common, but they were sold and you could buy one of these.
Rover 1S60
Here in the uk they have started using small automated gas turbine generators situated on industrial estates to boost the local grid all the noise is directed up so you cant hear them at ground level .
That high pitch whine is NOT quiet! It is quiet when it is off.
How exactly is this quiet???
Man what’s the cost of something like that and being made in Japan is definitely quality
I saw the switch for 50/60 hz on there, but it looks like the output is 100V. In the US, we'd need 120 V. Is that what the other switch is for? (at the top left)? I am also wondering if there is a split phase / 240 V option? This is really neat, thanks!
100V is the standard in Japan, where it was made.
@@nigelgunn_W8IFF interesting that they have it switchable between 50 and 60 Hertz then.
@@TheFeaz Not at all. Japan has 2 separate grid standards. One being 50hz, the other 60hz
@@Melanie16040 wow, I never realized that. How the heck does that work? So many things that are built to run on AC are highly dependent on the frequency, way more so than the voltage. I'm thinking of clocks and motors in particular, but I can imagine just about anything that doesn't first rectify the current to DC.
Half of Japan is 60Hz and half is 50Hz. Depends where in Japan you live.@@TheFeaz
i would be absolutely stunned if the waste heat from the exhaust also went to heating water, even if it was an optional extra... i dare say its EGT at the outlet is still well over 100C. seems a shame to waste it...
That is so cool what a neat setup!
I would love to get my hands on one of these.
“Thunderbirds are Go…..!!!!! “
Where do I get one of those my neighbor would love it
Where can I buy one of these?
What would this be used for... I mean other than on a jobsite or off grid it's entirely too loud
Airport bu service! Fuel avil! Expensive and low output.
I have not been able to find information anywhere, the only direct link ends up in a 404 error
This is freaking amazing. Blows a small air-cooled generac out of tge water
So this is what powers time travel... thought it would be louder. Not bad.
can it use diesel
It more than likely _could._ But I wouldn't. I used to work on Huey helicopters and you could use diesel as fuel in emergencies (as opposed to jet fuel)... but only for limited amount of hours, and then the engine had to be inspected. It burns at a different temperature which can stuff the turbines and or other components.
@@timhinchcliffe5372 there's newer jet turbines made for diesel its an altered jet
@@TimSmith-vl4qk as long as it's designed for it, it would be fine. But if he had that particular engine running on kero, I highly doubt that it would be designed for it.
