IHI Dynajet 2.6 micro gas turbine generator fully start up and shut down cycle at home. 

i got loud crs for that,and trucks LOL

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.

Just knock on their door and offer some power.

@@paradiselost9946you can buy the Dynajet aux phase cancellation unit. It quiets it down.

​​@@paradiselost9946you're not going to put a muffler on a turbine engine. It won't tolerate it.

Bonus points for having the Hobbs clock like a lot of aircraft.

Exactly.

@@stevebot I think a lot of machines have those, probably comparable diesel or gasoline generators do as well.

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.

@@yes-man1112 Same to you brother!

Rover made a small gas turbine fire pump. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-X_anKq-AUVY.html

I would love this thing even if not 1 volt was produced

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

sound only gets more full on lower freq. and the exhaust temp goes up

It only makes this noise. It doesn't load up at all lol.

A gas turbine will run at a 100% speed with or without a load

they are twist-lock plugs, you'll yank the cord out before the plug

lol googly eyes

Yes, they don’t look happy lol

🫨

Oh! Well, 67 dB... that makes all the difference.

How do you make solar gas?!?

@@zombieregime Solar Turbines is a brand of industrial gas turbines located in San Diego CA. The name Solar dates to when the company was called Solar Aircraft Company back in 1937. Today you can buy a 16.5 MW gas turbine that starts to full power in under 5 minutes.

I did my college capstone on my universities natural gas CHP unit that had 5KW peak and produced super-heated pressurized water (~200-220 psi) that was stored in 1,000 gal tanks to supply the campus. Very interesting to learn about and to see up close in person! Still need to make a return visit and see the inside of the turbine during planned maintenance

When I worked out of the Highlands C.O. In KCMO(2003) they still had 2 turbine gensets in the basement, but I think they set a new Caterpillar behind the building as they used way too much fuel and parts were unobtanium.

most over the road trucks have apu units on side that make 6,000 watts,and the little cat motor or cummins runs the ac on belts while the apu gives house current to what ever they want it for--the coolant during the winter provides heat--they only burn 1/4 gallon a hour of diesel-i want 4 of these turbines to power my little plane!!

Exactly right! The exaust gas temp is as high as 350℃, it is hot enought to warm the water

@@yes-man1112 Better yet, use the exhaust to heat a refrigerant-driven turbine to increase your electrical output (especially at higher load) and then use the waste heat to heat water. R134 boils at 165 degrees F.

@@yes-man1112 Or power a sterling engine with the waste heat connected to another generator head.

@@howiroll740 Heat water and run the steam through a small turbo. This is the basic concept of combined cycle power plants.

Pro tip: Skip the heat exchanger and pipe it directly into the home so you don't have to struggle through the apocalypse.

@@darkpixel2k Heck, just bring it into the living room and huddle around it for warmth. (Sadly people really do this.)

Use the after burner option for bbq’s

I want it. I dont need it, but my own APU for the garage is just too cool.

@@mikehilbig8280 “I want it ,but don’t need it” is why I have 3 acres of sh%t and tell my wife I’m storing it for friends .. I’ve recently came clean with my grand son and provided him with the key to Pandora’s box anticipating that day will come he’ll have to call American Pickers 😳😂

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!

@@hhiippiittyy But also on that, the stupidly high pitches of a jet engine fall off at short distances quickly, plus can't go through walls at all basically, so you can put up some bits of wood and it'd dampen the sound quite a bit

@@hhiippiittyy That depends on the human voice ;) But also it should be kept in mind, these days, most recording devices use MEMS or small electret microphones which have resonances in the higher frequencies. Plus most playback devices (phones, ear buds, TVs) have small diaphragm speakers, which also inherently have resonances in the higher frequencies. So the response/reproduction curve across the spectrum tends to get all out of whack above 1khz, making relatively benign levels of high pitched tones absolutely piercing. The typical 1200hz censored bad word 'BEEP' is annoyingly loud on this 40" vizio D series I use as a monitor (im old. I dont need glasses....just bigger flat screens XD ). Of course, the corner I have it stuck in doesnt help, I'm sure.....but still......

4.5 l/h….wtf…. The max power is only 2.6kVA? The numbers you have given might be wrong or this thing is just absurd of the numbers are true. A 2.2kVA Yamaha genset consumes about 1.25 l/h at full load.

@@cypher10297 is that Yamaha genset internal combustion? Because this is a turbine gas generator and i imagine some form of takeoff shaft to spin the dynamo. There WILL be differences. But you know what's better than no generator? Any generator.....

Oh god no, the opposite

Yeah, if you're old like me and your high frequency hearing is shot.

Fellow Utahn spotted!

Yeah -- attached to a snowblower!

How about a lawn mower or floor burnisher!?

@@leechjim8023 excellent idea. There is a utube one of the chainsaw manufacturers built a prototype jet turbine chainsaw.

That's what I thought, generators don't forgive poor maintenance, especially Honda... so the longer between intervals, the less likely this will happen.

All labels being in Japanese wasn't enough of a clue? ;)

@@FrietjeOorlog Technical is my first language, English my second, Japanese is bit farther down on my list of language familiarity! Though I did notice it was Japanese upon further inspection, once I noticed the power output!

IHI (Isuzu Heavy Idustries) is also a clue that this is Japanese in origin. Also, that it is 50Hz 100VAC also is a clue to what part of Japan this genset was meant for.

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.

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

not a big problem could be make for 120 or 110

Perhaps you are thinking of the 50 - 60 Hz schism?

Yes, exactly !

Sort of, but given the definition, you could actually have a regular piston-engine generator as one.

Yes! An expensive apu!

Just run it at 60 Hz through a magnetic field and you have an MHD generator putting out 60 Hz AC directly. ;-)

Interesting fact gas turbine can run on any liquid or gas that will burn ,if 1) will flow through filters 2) flow through injector

4.5L/hr at rated output. Pretty thirsty compared to a piston inverter generator making same output.

@@juliogonzo2718 Exactly. And kerosene is an expensive fuel, not like the old days, when it was much cheaper than gasoline. Still, pretty darn neat!

You are correct.

its a strange thing, defining the power of a jet... at its very heart, all engines take in a certain amount of fuel, which has so many calories, and a certain amount of air... use the fuel to heat the air, make it expand, and some of the expansion is extracted as useful power, some is used to drive the engine itself, and the rest gets dumped. a turbine makes "lots of power" simply because it can take in a huge amount of air, and a proportionate amount of fuel to heat it up. unfortunately, it cant heat it up very much before it melts itself, and it cant compress it very much before hand to maximise what it can extract... so power = huge fuel consumption, NOT "better efficiency". for high speed jets, they use a small amount of fuel to travel a large distance. thats good. for a cropduster, theyre pointless. you wouldnt make a profit. (some are running turbo props they, arent they? sigh...) anyway, make them huge, and improve certain thermal feedback, losses, etc... they get pretty good. the main reason is volume/surface area, and the thing about tolerances/clearances. the blade tips need say, 0.5mm of clearance. regardless if its 2 inches wide or two foot wide. obviously, its a much higher proportion of leakage through the clearance gap on the small engine... get into the steam turbines and theres all this tomfoolery of bleeding pressure off at stages to act on the bearings and glands so leakage always happens in one direction, is reduced, blah blah... bit more involved than they look at first.

@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.

Nice, especially the turbine sound is too coooool

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

I almost couldn't even hear it over the jet airplane in the background.

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.

Please - what is the fuel burn per Kw ???

Yeah the fuel burn on this unit is crazy. 1 gallon per hour for a 2.6 kW unit is pretty bad.

@@pjeaton58 4.5L/hr at 2.6 KW full load

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.

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.

I would imagine it would be best for small airport lighting during poweroutage

Indeed

When he flipped that one tiny switch up, it spooled up. Didn't take but maybe 5 seconds from idle to ready to load. Then you heard a contactor click. That was the generator being ready to output power. I was amazed how high idle is. The spool down time from "load" to "unload" was pretty long. If that "2.6" meant 26 KVa, I'm going to go look for one. But if it means 2600 watts then I'll pass.

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.
