- Gas turbine engines, known for their lightweight, power, and high thermal efficiency, have long been eyed for automotive applications. Historically, automakers like Chrysler tested gas turbines in road cars in the 20th century with mixed results. Despite their efficiency at high loads, their performance at low loads made them less suitable for city driving. As the automotive industry shifts towards hybrids and electric vehicles, the focus is now on using internal combustion engines mainly as range extenders. Here, gas turbine engines, especially microturbines, show great potential. Companies like Jaguar Land Rover and Capstone have dabbled in using compact gas turbine engines, often in collaboration with other firms, to create prototypes. These microturbines offer impressive fuel efficiency, versatility in fuel choice, reduced maintenance needs, and significant weight savings. As hybrid vehicles gain popularity, the incorporation of microturbines could revolutionize the industry.

Better than all electric in my opinion.
Same.
A hybride would be great for a long haul truck. A gasturbine should deliver 1000 HP all the time to be efficient. The truck would drive on battery and when low on battery the turbine would start and deliver power for driving and battery. And then stop again when the battery is full. With an engine which can run on any oil or alcohol it could for a low price per mile.
This is the best setup I've seen. I think a cool way to showcase this idea would be by forming a car racing league featuring gas-turbine/electric hybrid motors. For flat-out racing, I wouldn't use batteries, I would use graphene supercapacitors. I think they should use the technology in tanks and other military vehicles since you can run the vehicles on electric power in a sort-of-quiet stealth mode. Also, you can discharge supercaps much faster than even the best batteries, so you could run electric weapons like lasers and other energy beam weapons off the same power.
This sounds good to make conversion of older gas cars to Gas-Electric. This is exactly how the M1 Abrahams gets its propulsion power, a gas turbine.
I was not aware of this development. It is very exciting news!
This system should be adopted to reduce gasoline consumption and pollution due to complete burning of fuel or more complete.
In the late 1960's Rover in the UK produced two prototypes the first was based on the Rover 90 saloon Registration JET 1. The second was a sports car all aluminium with a rear mounted transverse gas turbine. I used to cut the lawns of the MD of Rover and he sometimes used it to commute to the office!!
why hasn't this taken over the truck and car market already? with a cheaper running vehicle and costs that could run on ethanol burning cleaner emissions with 500km in one tank this is crazy why isn't this a global thing already
Because at 35% thermal efficiency, it is not efficient enough to replace the turbo diesel engines at 45% thermal efficiency, and it is very expensive.
Engeneers think to the end and balance all parameters to stop or move to good results.
Terribly inefficient at low speeds.
Turbine engines are an engineer's pet project for the rest of their lives. The way the engine is to be used, the materials available, the manufacturing processes, all affect the design of the engine, and everything needs to be accounted for when pricing a new turbine. A properly built engine is going to be expensive and require a technician familiar with that particular engine in order to service it properly. That's not to say that an engine can't be produced and sold for a reasonable price, but the technology needed to do so hasn't been around for very long, and manufacturers don't want to sink large amounts of cash into a product that may or may not be an economic success.
While this is true the ONLY function of the Gas Turbine is to run a generator at the Turbine’s most efficient speed (98%-100% max RPM).
Once the vehicle batteries are recharged the Turbine shuts down until the batteries need to be recharged again.
This idea is most certainly viable and already proven in testing, the biggest challenge is most likely government overregulation and public perception.
Fuel cells sounds like that 😮🤩
That's the sound of the compressor, which pushes the air through the filters into the fuel cells.
Hardily a new technology - just revisited hopefully to make it practical and marketable
Too many people in this section not getting the importance of combining gas turbines as electricity generators with electric motors. Suddenly fuel economy is awesome, and at low speeds you run off batteries/capacitors.
A better option is the combined cycle microturbine system. This is an innovative energy solution that enhances efficiency by harnessing waste heat. It starts with a microturbine that generates power by burning fuel. The exhaust heat from the microturbine, typically lost in conventional systems, is captured by a Heat Recovery Steam Generator (HRSG). This HRSG then produces steam, which powers a steam turbine to generate additional electricity. By utilizing both gas and steam turbines, this system maximizes energy output and significantly reduces waste, making it highly efficient and environmentally friendly
When a turbine is up to speed I wonder if road vibration or hitting a pothole may disrupt the rotation enough to cause damage. If they are robust enough to deal with the vehicle going through a bit of abuse, then I think we should start using them yesterday. Get everyone a 40-70km battery vehicle with a micro-turbine range extender please.
Does a bump in the road cause your engine to have damage?
it only makes sense if you can run it on some green fuel like natural gas or alcohol. if you're going to still put in regular pump gas may as well not bother and use regular engine.
😉👍👍👍
In consumer automobiles these are better used as a small range extender to continuously charge EV batteries at a consistent rpm. I.e. Cosworth’s Catalytic Generator.
I thought of this YEARS AGO! Sadly I wasn't born rich enough to do anything with my idea! (I even came up with a flying car using this principle)
❤
lots of testing, then maybe!
Townscaled gas turbines as range extender in hybrid cars/trucks suffer from low efficiency!
However, if any new developments in compressor and heat exchanger design this might be game changer (e.g. micro structure heat exchager, concentric and counter rotating radial compressor wheels).
I think this could be a true step ahead.
And why do the downscaled turbines suffer from low efficiency?
Tanks and helicopters use them so it shouldn't be that bad
@@commieSlayer69 1. Physics of fluid dynamic: boundary layer losses do not scale. They get increasingly dominant for small turbo machines (Viscosity, Reynolds number).
2. Scaling down causes reduction of channel cross sections by the power of 2 and volumes by the power of 3. Therefore not just increases gas friction losses but also heat losses (surface versus volume ratio).
3. Gap losses between rotors and stators getting more dominant as tolerances can't be scaled down (coef of thermal expansion).
Helicopter Gas turbines already suffer but here it is fuel consumption tradeoff with favorable power to weight ratio.
For cars where weight is not that critical but fuel efficiency is, one could go for lower pressure ratio / larger turbo machines and additionally gain efficiency by adding a heat exchanger. However, this significantly adds to the overall size of the gas turbine relative to its power output.
what if a rat or stone is sucked in the turbine.
Chevy had one in 1964
I want a. Abrams
wise…
They didn’t take off 60 years ago due to fuel economy, they especially won’t take off today due to emission regulations
They literally create 95% less emissions than standard engines, but nice try!
It was bad on gas because turbine engine get more efficient the longer they are ran continuously this is why they are used in planes, because unlike cars planes don't stop often and will run continuously for hours on end
@@tristanheaton2127 They are NOT used in airplanes because they are more efficient. They are used because their power to weight ratio is so high.
They are less fuel efficient when run at low load, like when cruising in a car. They are efficient when operated at continuous heavy load, like turboshafts or turboprops in a plane or helicopter.
Hybrid system solves the variability in load problem by having it come on only when the battery needs charging and run it at the optimum load and turn off.
obvious fix: have 8 turbines, and turn 7 off wen not need, and 1 in city 7 off etc and run all 8 to accelreate then turn off 7 whens stop
Gas turbine engines are only 28% efficient. Steam turbine engines though can be up to 50% efficient.
Even if your number would be true, that would be 40% better than a petrol car. Sure less efficiency than a diesel.
@@dieabsolutegluckskuche5174 28% efficiency is 40% better than a petrol car? A petrol car is only 20% efficient? Dude it's not 1912 anymore. Learn something.
@@shadfallfan a diesel is a little bit over 40% efficient. Petrol cars aren't. Basic facts.
@@shadfallfan Also it would only be used as range extender, so for 90% of time you run at 64% efficiency. Because on most days Americans drive under 100 miles. So yeah even if we would say that petrol cars would have the same efficiency as diesels, on a yearly base an EV with a range extender would be more efficient.
Learn something.
@@shadfallfan btw read the comment again. I didn't say petrol motors have a 20% EFFICIENCY, I said that a range extender would be 40% more efficient because 20 + 40% = 28 %
I think it's the way to go , we can still have our traditional factories build them and they seem very efficient , yes if course we would still need the oil business (Biden is friking crazy if he thinks otherwise , c'mon man where would we get plastic , it all comes from petroleum bi products . I have no problem with electric vehicles , but they do need to be self sufficient , I can think of nothing that would infuriate me more that being low on a charge only to find the only charging station in 200 miles is broken . Besides who wants to go on a trip and stop every 4 hours for an hour to charge up the car , no way ! I want my freedom to drive wherever I want when I want . I have to say it seems like somebody doesn't want us to be able to travel at our own will .
An interesting thing about turbines is you can burn just about any fuel in it. Possibly, a mixture of water + alcohol + glycerine would work. With a very low fuel cost, you offset the lower efficiency.
Oh yes my favorite combustible liquid, water.
@@shadfallfanhahah, might help pressures to a fraction but probably not much if at all
@@appelmelk5664 Literally no. But nice try!
@@shadfallfan a try is a try
@@appelmelk5664 A fail is a fail. Congrats!
Why does the AI sound like it was run through Google translate? Love the topic, but the grammar is killing me 😭
"new-speak".
I still think hydrogen fuel cells would be a good alternative. You see major manufactures of electric forklift equipment already doing it. And yes, you could power your car with electricity generated by such a fuel cell all the same. And hydrogen is way easier on the environment. I think the battle as far as you and I are concerned still comes down to greed. The struggle to put money into who's pockets for this. You might find that's a huge contributing factor rather than what we can develope.
Well Chrysler tried it in the early 1960s and it didn't work out so well. I don't think there is any technology at this point that's going to make it feasible.
Quasiturbines
They tried electric cars in the early 1900's. There's no technology to make them feasible 🤡🤡🤡 clown logic
Plus, turbines are operating at peak efficiency driving a generator. Which powers the drive chain and recharges batteries.
30 years too late (seen this tech before, 30 years ago). This will never hit the consumer market, and really, it should not hit the market.
I saw them try electric cars 100 years ago so obviously they don't work 🤡🤡🤡
We have heard this before... & it did not pan out...first we must get rid of the vested interests in fossil fuels before anything can change... there is suppressed technology enough...
Lololol let me guess you believe in water powered cars and 200 mpg carburetors 🤡🤡🤡
