Ok hear me out. Fusion Reactors scaled down into a car. Basically a huge lithium doughnut at 10,000,000C powering a steam turbine. 10,000RPM automobile time

Fusion Reactors?Iron man?It's science fiction.But there is Nuclear battery now.It is used in aerospace, pacemaker and some special military applications. It can provide a million times more energy than a chemical cell of the same volume.

https://en.wikipedia.org/wiki/Atomic_battery

Fusion reactors aren't really sci-fi anymore. You got experiments that have been running since the 50's also the sun exists. Hopefully in the 2020's ITER works and we can start producing Fusion Reactors. Only problem is lithium and initially starting the reactor. But the pay off is worth it

[Slavakino]

I reckon a way to increase Car Engine efficiency and produce less soot and gasses is perhaps having it in a vacuum where pure oxygen and petrol are only pumped in to move the car instead of the old Air + Petrol. Might be a bit tedious to work with and implement but for the long run it would be worth it and less consumption

Yes much more energy, but only at a very slow rate. These things are good for space, but they don't compete well with solar for low-drain off grid, ie remote locations. Reason being that in remote locations there's nothing to stop bad nerds from stealing them. That used to happen to solar panels on remote equipment, back when they were expensive.

"spacecraft, pacemakers, underwater systems and automated scientific stations"--Wikipedia

Well I hadn't even considered pacemakers. The idea is a bit scary frankly:
"No missus Tubbs you won't need to change the battery, there's a nuclear reactor inside you now ... don't google it"
Underwater, fair enough, not a lot of vandals there. Remote locations ... only VERY remote, like uninhabited atolls.

The things do have uses, and maybe stronger versions could be built, but note they're old technology so dramatic improvements are not likely.

I know ITER.It's assembling.I have to tell you, before it starts working, there is no substantive breakthrough in technology.In addition to one of the experiments of NIF, no other experiment has realized the output energy and excess input energy.Far from commercial use.Maybe in a period of time, it will be a hundred years for human beings to study this thing.
By they way,nuclear fusion is really beautiful

Remote locations......I think of the Soviet nuclear lighthouse in the Arctic.It has a small nuclear generator, but I can't find out how they work.
Now it's in a dangerous state because no one maintains it.

Liquid oxygen (LOX) is surprisingly cheap. I think because it's a byproduct of making liquid nitrogen (by refrigeration), but that means it wouldn't stay cheap if it was used more. For now though, LOX to improve the temperature and clean burning of coal, is quite practical. It costs a little more than using air but saves a lot of pollution. It's also used in high temperature incineration (there's debate about whether that's better or worse than landfill, from an emissions point of view: it releases all the carbon plus carbon from the fuel ... but none of it as methane).

LOX does need to be kept cold and/or compressed, and of course decompression makes it suddenly very cold. That kind of cold is a threat to human life, AND pure oxygen accelerates fire like crazy. For both reasons I don't think it should be in a standard car. Dragsters and rockets can use LOX.

Supposedly for a 50L tank of petrol you'd need 700L of Oxygen to supply it. Problem is Oxygen is piss hard to compress. Perhaps with pure hydrogen it may work better

Hydrogen energy vehicles are under development.The problem now is that liquid hydrogen is not safe, and a series of metals that store hydrogen are being tested in the laboratory.Its principle is fuel cell.Open fire is too dangerous.
I have to say that I was learning these things in physics and chemistry class in middle school more than ten years ago. Now they're still in the lab.I feel like human beings are now in a technological bottleneck

yeah

I hope there's a breakthrough with some other kind of fusion. The timeline of tokamaks is just depressing.

Hmmm. Maybe some sort of polymer made storage might work? Probably not. But something like a Hydrogen based combustion chamber would be lovely. I'd hate to see manual gearboxes go away. Shits fun to drive

A conspiracy theorist would say that all the good ideas are being bought up by Big Oil (and maybe Big Auto) and stored in the trash.

The theory doesn't really work though. Patents can't be kept secret.

Maybe electric cars can offer you 'sporty' features to make up for the lack of gearbox. Going sideways not just forward and back. Or stunts using motors in all four wheels.

Nah electric cars can't do shit to replace manual. These sporty features probably might screw up the motors. The feel of having a manual gearbox and driving it is fun and has that sort of feel that an electric car can't match.

I learned on a manual (so my license would have an M on it) and mostly drive manuals. But sometimes I drive an automatic, and frankly it's about the same. An auto changes gears almost exactly the same time I would.

There's occasionally a need to crawl forward or back, or get grip on a difficult surface, for which the clutch is good. Not a big deal imo.

I can't interest you in going sideways?

[Galloism]

I reckon a way to increase Car Engine efficiency and produce less soot and gasses is perhaps having it in a vacuum where pure oxygen and petrol are only pumped in to move the car instead of the old Air + Petrol. Might be a bit tedious to work with and implement but for the long run it would be worth it and less consumption

Probably not - the weight required to maintain a near vacuum would be immense, and carrying the oxygen around also adds weight (while air can be gathered on the move).

[The Two Jerseys]

No. Bugger off flaming environmentalist. Also, electric cars are not viable when most energy sources come from coal, also no manual gearbox. You're better off developing a nuclear car, advancing Hydrogen or LPG. Electric cars are for people who are environmentalists who know jack about the environment or people who know no nothing about cars. Petrol may not be perfect but it certainly pollutes less compared to electric. Hell hybrid exists for a reason.

You heard it here first boys, the Ford Nucleon is back on the menu

I have a feeling that the reactor turned out to be larger than Ford expected...

Probably not - the weight required to maintain a near vacuum would be immense, and carrying the oxygen around also adds weight (while air can be gathered on the move).

There's no point when it's air (with a bit of exhaust I guess) and what's going to be drawn in, or pumped in, also contains air.

So would it improve a fuel/oxygen engine much? I don't really think so. It's a little bit of air at the top of the cylinder (with the piston up). Maybe getting vacuum there instead would reduce NOx a little bit but I'd just go with the large reduction of using (mostly) oxygen instead of air. Maybe dispense with the vaccum and flush the last of the exhaust out with oxygen.

Price of oxygen is going to go up, the more of these on the road, and that's going to finally kill the idea. A shame.

Ok hear me out. Fusion Reactors scaled down into a car.

Also pure oxygen is extremely volatile.

Ask the crew of Apollo 1.

Ask the tanks of Apollo 13, too.

Hydrogen is not really better than electric anyways. Because you have to produce the pure hydrogen using electricity, if you are using dirty electricity, you still produce pollution.
Sure nuclear and such can make it cleanly but they can make electricity cleanly without the extra step.

Hydrogen just stores electric energy because hydrogen is too volatile and thus is not really available outside if breaking up water using electricity.
Hydrogen is just a low density very explosive battery.

It is hard to see where it is any better than electric with a battery.
