Randomly trying to sleep tonight I started thinking of ways to prevent c02 emmissions from cars. The whole EV thing doesn't seem like a great solution right now, and honestly I figured there has to be a way to convert the emission from cars (which mainly comes from the tailgates/pipes in the back) into something safe.

So I did a quick search on the internet. What a world we live in where you can get any information you want at the touch of your fingers even at 3 am. Anyway it turns out you can totally capture the co2, but there are a ton of problems with it, mainly that cars emit ALOT and that 1 gallon of gas creates many pounds of Co2. Basically to drive 125 miles would create something like 100 pounds of co2 once you actually converted it into a solid. It would need to be offloaded somewhere, and you still would have problems coming up with a system that collects the co2 without interfering with the engines operation.

But what if you didn't have to collect it from the tailpipe at all, or separate it from the water, or freeze it to make it a solid. What if you just had the cars mainly drive under covered freeways, in tunnels etc, so that the co2 emissions would naturally raise up, but instead of entering out atmosphere, you have collectors that grab it in gas form, store it, and allow it to be used afterwards? It would be alot of gas, but a system could easily be made to store it if needed and transport it. You wouldn't need to worry about hauling it around in the cars we use, no need to worry about the water either (it would dissipate just like it does currently with cars). This would require large projects, but multi-layered freeways, or tunnels is already a solution we could use to help with traffic, and by building them to capture Co2 emissions, you could solve two problems at once. It would probably be less expensive than switching everything over to EV, creating a power grid that can handle that, charging stations etc.

I am a bit confused that this information has been available for so long, there are even systems set up to convert co2 in a car safely, they just are expensive, but it has not been implemented in any large way.

There are ways to use co2 to create electricity, so if you built these freeways with co2 collectors that then converted the captured gas into electricity, you could in theory power a city by the co2 emissions of the cars driving in it. Not only solving the emission problem, but the power grid problem for EVs. In theory you could make a TRUE hybrid car that uses EV when not on the freeways, but uses gas when on them.
