Fusion propulsion next pls

just use Mr.Fusion Power Plant like Doc Brown DeLorean..

Could make for an interesting endurance challenge. Which will last longer: three uranium fuel pellets or the driver?

Nah. I was all for gas but given the current situation we might need to revert to coal-powered engines.

Red flags could last thousands of years!

Same. Stuart does do a good job of making complex things more understandable and he did this well here.

I doubt he got the expertise. He's not an engineer.

@noahbpm Exactly, it's a turbine. That's how it works.

@noahbpm IIRC the MGUH is essentially a turbine in the exaust of the combustion unit that turns as exaust gas runs through it

@@Bluelink13 That is interesting. Without knowing any details of the method I would have thought that there would be some kind of a heat exchanger.

@@MikaTuukkanen A heat exchanger would really just add an extra step. No need to heat a liquid into a gas when the engine itself already provides it.

When you study electromagnetism in-depth later in IB or A-Levels, look up the MGU-K video

The new cars still look gimmicky and childish to me but the good news for you is that the wheels are open again. No rear wing though. Formula E in a nutshell, gives with one, takes with the other.

The entire point of formula e is that it’s different. Why would they emulate other open wheels series. I don’t get your mind set

Open wheels are inefficient though, so its understandable. Personally i like their looks.

i love the gen 2 FE cars. they looked way cooler than the out-going F1 cars from last year imo ('22 spec F1 takes the cake over both tho)

@@F1ll1nTh3Blanks They don't use any significant downforce generated by parts that could break off so the drivers are encouraged to race aggressively. I think it pays off with exciting races, especially now that they've improved the quali rules this year.

Glad to hear! Though the time, quality, and research that takes making his videos, I think an upload a week is perfectly adequate.

Americans have a reputation for boiling water on the stove or in a microwave, which is seen as bizzare alien behaviour in the UK 😅

Good luck with your voltage!

Thank you, you're doing what I wish my teachers did when I was first taught thermodynamics

This will be one of the best ways to make the cars more efficient but may make them too heavy. I have to say allow the teams to use and much as they want the MGU-K as much as they want and have as big of a battery as they want. Also integrate the system into the brake pedal just like an electric car. In other words let the teams figured out how they want to use the hybrid system.

@@mvargass yeah i also think the mgu-k should be a lot more free which could lead to some interesting new tech :D and yeah it would be interesting to see what they come up with considering the weight

weird idea, put a generator inisde the front wheels to use as a brake

@@alejogonzalez4997 Already been done.

@@alejogonzalez4997 i think the unsprung mass would be to large for good performance

4WD F1 will be a tragedy, it’ll take away a lot of of the skill necessary and wet races will no longer be exciting

@@TedMan55 WRC shows that 4WD doesn't mean full traction all the time. Front/rear balance when getting on the power out of a corner. Controlling wear on the front tires. Adjusting to front wheels that are fully electric driven while the rears are a combination. How much do you push for front down force even in low speed corners so you can maximize your drive out. Oh and the fuel tank gets smaller cause during breaking most of the energy is going through the front wheels.

Then we can also go into delta G and more , really would love him to get experts in for 45min deep dive topics

well it's the extra space that said separation requires that drives the increase in pressure that drives the pistons. no? or is reaction just shooting shit atoms and shit everywhere?

@@rektiumstuff3245 it's more elemental than that. It's an essential rule of chemistry that breaking bonds requires energy and making bonds releases it. A critical but often misunderstood aspect of chemistry.

@@reviresco2073 well yeah I'm not disagreeing with that but don't the gases created by burning gasoline have a higher volume? Because the heat energy that gets created from forming bonds doesn't propel the car.

Sharp thinking!

The teams will only be allowed to use the front motor for braking. But there where made suggestions to do AWD drag-races, which eventually got abandoned.

Unfortunately, despite the amazing efficiency provided by the MGU-H, the MGU-H is still a very, very complex AND expensive technology that is not practical for anything that isn't a multi-million dollar race car like an F1 car. There is no practical value for the technology outside of F1(or racing in general). For the engine manufacturers(who are also car manufacturers), money and effort spent on the MGU-H is money that they pretty much just threw into F1 alone. They can't use what they learned in making the MGU-H to improve their road cars, for instance. Putting the expensive MGU-H into road cars will only bump up the cost of a regular road car. And that's on the assumption that the average 100~ horsepower road car can even get the MGU-H to work as well as it does in F1.

Converting mechanical energy back to electrical then back to mechanical, when a direct mechanical route exists, is also a great way to throw energy into the "black hole". Completely defeats the point of moving towards more efficient powertrains.

@@484berkshire You forgott about the batteries. Just replacing the gearbox by a motor and generator unit would probably be a bit less efficient. (although the difference is not that high) But the ability to store energy changes the whole equation: Because now you don't need a combustion engine that can run at the maximum power you need during a lap anymore. You need an engine that can run at the average power over the whole race. The differences you make up with the batteries. This means the engine can get lighter and can run at the most efficient rpm/load. So in the end you have an engine that is lighter and more efficient. So going serial hybrid is actually going more efficient.

@@burningSHADOW42 Except any weight savings you'd get from making the engine smaller and lighter would be more than offset by the correspondingly massive battery required to fill the power gaps. Or conversely, you could still use the same giant battery with the more powerful engine driving the wheels directly and end up with a much faster car. Plus, in a racing context, average power needed over a lap isn't much lower than peak power, since virtually all acceleration happens using peak power anyway, so any efficiency gains would be negligible, or actually negative when conversion efficiency is considered.

@@484berkshire The battery wouldn't be that much bigger, especially if what you say is true and the cars run at peak power most of the time. And bigger batteries are actually more weight efficient. For comparison: the current Formula e car have ~200MJ batteries that weigh 385kg. In Formula 1 the battery weighs between 20kg and 25kg and is allowed to store 4MJ. (The Race speculates that they have up to 5MJ battery size) Both cars weigh about the same at the start. So Formula e has about 40 times the electric energy on board. This means that the Formula E bettery has about 2 the MJ/kg that the F1 batteries have, so battery weight should not be that much of an issue. Especially since the Formula E battery is a spec part, so Formula 1 going down that road would actually help battery development. As for the engine weight: an engine that is optimised for efficiency at one specific rpm can be lighter and have reduced cooling needs. If you wanted to go completely bonkers you could allow (micro) gas turbines as power source which are much lighter and don't really require an external cooling system. Although good comparisons are hard to make as there are no good number for F1 engine power and some of the power (MGU-H) is created directly as electric energy.

They can charge it during the formation lap, if needed.

All of us people outside US have to look out for such things. After all we don't measure things in freedom units

The layouts were designed to be intentionally tight to allow cars regenerate energy through hard braking.... They cannot just chuck long straights into hard braking corners every time because overregen will put wear and tear into the PU very quickly and cause a catastrophic disaster of battery explosion, that's why at the current state they cannot run a full Grand Prix road courses aside from Monaco....

FE is really good this year with the improved quali rules to make the standings a bit less random.

Battery tech is definitely important but yeah the most important thing is for F1 to stop doing these ridiculously inefficient calendars with huge carbon emissions.

Fuel cost, a v6 will inherently be more efficient than a v12 because the v6 doesn’t have to burn as much fuel.
