What is the most thermally efficient engine ever produced?

You can produce these. That doesn't mean they'll have an efficiency even close to the theoretical efficiency, but that wasn't the question.

it is not 100% effective but still
/thread

I was OP though.

I was wondering what was the most thermally efficient engine actually built.

Some work was done on Stirling Engines for cars by NASA in the 70's/80's but when the gas crisis died out they called it off

Who is this fluid druid?

no kidding now i have to fap

light bondage is amazing

She's my sister

I'm guessing this is just a one-off photo? Google is not showing me any more.

not a set? Any more where the clothes get torn off sequentially and slowly?

>Carnot engine

>the reflection in the tape
The guy takingthis picture has a moustache.

A Carnot engine is a theoretical engine to study Carnot efficiency.

Are you thinking of the Stirling engine?

Post more plzz

Lol. You think he raped her?

Y'all are fucking retarded.

why did you upload a photo of my gf?

hnnnng

The BBC engine.

Turbo charged Diesel

95%

Commer TS4

Probably this. Although that's not a motor per se.

It's obviusly the EMDrive
Sorry, I'm not good at shitposting.

I was taught this last semester in Biochem. But the teacher also said something like the fact that the scale of movement and exchange of energy is so microscopic, that it isn't exactly the same process as a macroscopic axle generating measurable mechanical force.

the bicycle.

The current Mercedes F1 engine is apparently over 50% thermal efficient, but i'm not sure if that is just the ICU or including the MGU aswell.

You might surprise yourself

Probably an electric engine unless you're talking about heat engines.

does no one have the video for this

>What is the most thermally efficient engine ever produced?

Hot air balloon burner.

but it only goes up.

Engines that are designed to produce heat such as a home radiator.

But that may be cheating since by design it's supposed to lose efficiency by generating heat, I dunno.

Why hello there little girl, are you interested in engines that maximize useful work output?

Light bondage has now become a fetish

PLEASE GOD SOMEONE HAVE SAUCE

Kyubey did nothing wrong

Contrary to feminist dogma, you can't really rape the willing.

You'd be surprice at what the general public, the justice and the Estate would think of your logic.
Only if you are withe that is.

the combustion one in cars otherwise literally the whole world wouldnt use it

Bump. I want it too.

that slit between that hussy's legs wwwwwwwwwwwwwwwwweeeeeeeeeeeeeeeeeeeeeeeeeeeeeoooooooooooooowwwwwwwwwwwwwwww laddy i'm hard as a rock and 'bout to cum

where can i get one

There are electrical engines with twice the efficiency of a combustion engine. The whole world dont uses it in cars cz we cant make a good enough batery. But they still more efficient. What do you say about it?

so you're saying that it isn't efficient enough to be used with current technology?

EM Drive

electric to mechanical power!=thermodynamic proces you bloody retard
and guess how electricity is produced in the first place

Diesel engines in ships are more efficient, and probably also the most efficient in existence as far as i know
unless you consider a combined cycle as a single unit

The best combined-cycle power plants get around 56%-efficient conversion of fuel energy content( higher heating value) to mechanical work.

There's typically an 11% loss due to the difference between higher heating value and lower heating value. Then the main turbine converts 40% of what's left, and then the secondary turbine and possible tertiary turbine get up to a third of what's left after that.

It's reasonably close to what's possible with the carnot efficiency limit. They can certainly go closer, but it becomes very costly. Your engine becomes very big and expensive relative to its power output.

Ba-dam, BOOM - shshshsh!
