So today I spent some time thinking about cars and efficiency, right? Cars burn gasoline (or diesel) to go forward - the more gas they burn the faster forward they go depending on the engine, and they turn the gasoline into carbon dioxide, nitrogen oxide, and whatever else comes out of the tailpipe. The more gas the car has the farther it can go depending on the efficiency of the engine, with larger engines generally getting less mileage per gallon.
I was thinking about it, and what if there was a way to 'unburn' gasoline by running the engine in reverse? So the engine sucks up all the carbon dioxide and nitrogen dioxide through the exhaust manifold in the engine, then the pistons compress it back into gasoline? If you reverse the process, the car will just end up going backwards, sure, but if you got really good at reversing, you could in theory just drive places in reverse, suck up CO2 out of the air, and make gasoline and deposit it into the gas tank (for selling later, maybe). It makes environmentalists happy by reducing the car's carbon footprint and it makes a ton of money for the driver depending on how far they can drive backwards to unburn gasoline. Any thoughts?

uh combustion gives you co2 and h2o

You might be on to something here OP

CHEAP CHINA RUBBER SO GOOD HE HE

Genius, simply genius.
As I've come to expect from /o/

>>16703588
ive thought about it, i managed to compress the gasses back into fuel successfully. I still cant find a way to make the car go forward when doing this. it just rolls backwards.

I'll give you some cheap china rubber if you get my drift

You should learn about entropy, OP.
Actually you should probably start off with something like this.

You'd need to build a transmission with more than one reverse gear, to reverse faster and go on the highway and stuff

You would be defying the 2nd law of thermodynamics OP. I'm not a physicsfag, but the way I understand it is that a combustion reaction results in the hydrocarbons composing the gasoline reaching a more chemically stable state in the form of CO2 and H2O, etc. (i.e., the products of the combustion reaction will have less potential energy stored within their bonds). To reverse the process you would need at the minimum some device to collect the products of the combustion reaction, an input of energy from the environment into the chemical system to overcome the activation energy barrier, and some kind of catalyst.
The first part can probably be figured out, but the real issue I think is the 2nd and 3rd point. A combustion reaction, being a highly exothermic reaction, would have a very high activation energy threshold in its reverse direction. To get this energy would probably be more trouble than it's worth. As for the catalyst, you would have to ask a chemfag.

that'd be fine though
better yet just have it sit still while refueling
