This exists. It's called a Tesla.

If this was the case, wouldn't the engines have to be much stronger, thus heavier because now more energy is in the explosion instead of the heat+sound?

well, they already have retard boosted iron blocks and very very powerful aluminum blocks, so i dont think there would need to be many changes

same amount of fuel making more kinetic energy would result in higher output

>>14069505
What car is that?

>>14069605
some 90s civic or something

>>14069505
Wait, doesn't this mean that a steam-powed gas burning car would be almost 80% more efficient in terms of fuel use? What if you utilized the kinetic and thermal towards propelling the car?

>>14069505
I understand that your idea is largely hypothetical, still, i think it's unfruitful to discuss power, since you can boost that anyway by using nitros, more powerful engine designs etc so you wouldn't see anything already not seen in performance specific designs.

AFAIK large part of this inefficiency is exactly to produce more output power.

As you change the way engine operates, you get less and less power vs weight and more efficiency. In the end you get well insulated steam boiler engine.

that or you could now consume much less fuel to make the same power

Imagine we populate keplar22b, the atmospheric pressure is 2x earth atmospheres.
Every car now has double the power, and we start an intergalactic race series where races take place on both earth and kelper22B.

>>14069674
thats what i was talking about in op

>>14069584
What does volumetric efficiency have to do with anything here? Or do you just ant to admit that you don't know what volumetric efficiency is?

>>14069692
Wouldn't it also have twice the drag Copernicus?

>>14069692
the corvette still overheat
the GTR has still a glass trans
nothing would change

>>14070026
It wouldn't have twice the 'drag'. The formula used to calculate the instantaneous air resistance is a square function, meaning that doubling the atmospheric pressure may triple or even quadruple the air resistance ie drag

>>14069555
Fuck you dude. I for one love ICE.

>>14069675
You can get almost 50% thermal efficiency.

>>14070424
Aw shit nigga

It'll be relative then. 1.2 litres would be an upper level engine size and many people would opt to use 200-600cc engines for day to day use

anything over 2 litre would be taxed for excessive power, v8's would be government enforcement only and I6 would be virtually non existent due to being an obsolete cylinder arrangement due to the power of I4

>>14069505
Modern ICEs are between 30 and 40% efficient.
But if you could increase efficiency from 20% to 80% surely you just quadrupled power?
So a 150hp ecotec would make 600hp?

>>14070075
It's the square of the speed, numbnuts. It scales linearly with fluid density.

Supercharged. So not n/a

Less fuel would be injected and in a different way

If most processes didn't waste so much energy in the form of heat, or if we had better ways of harnessing heat energy, a lot of things would be crazy.
>Charge your phone once a week
>Fill up your car once every two months
>Nuclear aircraft carriers would need to be refilled once every 50 years
>Power plants would be twice as efficient
>Processor clocks would only be limited by the stability of the silicon

I'd estimate the planet would use 1/3 of the energy we do now, and we'd see massive advances in computing.

>>14070468
>So a 150hp ecotec would make 600hp?
No Ecotec without being completely built will make 600hp.
Remember, 600hp @25% efficiency and 600hp @100% (existing only in theory) is still 600hp.

more like 40% op

but it doesnt matter when a gallon is $2.00 and will get you 30+ miles. that's cheap transportation.

It seems everyone that has passed diesel mechanic school knows what it is, except for you.
