The volume and weight of emitted carbon would be too much. Now it is possible you could convert the carbon into a solid, and deposit these on the side of the road. Someone else could come along and collect these, which could then be used to produce more energy or perhaps as fertilizer.

Co2 is what plants and trees need to survive , global warming is a load of rubbish and just a big scam if you buy co2 credits from al gore you can pollute as much as you like. Lmao , the world has heated up and cooled down way before we ever lit a fire

Hello Brent,

You’re thinking of a device known as a carbon scrubber, a machine that removes carbon dioxide from exhaust gases and exhaled air.

They’re routinely fitted to power plants and industrial processes but they’re not practical as a method of capturing CO2 from vehicle exhausts.

The problem with vehicles is that they emit huge amounts of CO2. Gasoline is a long molecule made up of carbon and hydrogen, when it’s burned the carbon atoms join together with oxygen from the air to make carbon dioxide. Adding all this oxygen means that the weight of the CO2 that’s produced is more than the weight of the fuel that’s burned, it actually weighs just over three times as much.

In context, this means that if your car used 10 gallons of fuel (US gallons), then some 200 pounds (100kg) of CO2 would be emitted from the exhaust. Even if this was pressurised to 10 times the atmosphere, it would fill a tank about 150 cubic feet (5m3).

One of the problems with wind, solar etc is that they’re not practical for powering vehicles. They could be used to generate the electricity to charge electric vehicles, but battery capacities aren’t really all that good. Even the best electric cars need to be frequently charged up – fine for short journeys but not practical for longer ones.

An alternative would be something like a hydrogen fuel cell. This is a self contained power unit that uses hydrogen as the power source, when burned with oxygen it produces the energy to power the vehicle but the only waste product is water.

Little big for a car so far

Yes, it is a thing called a tree.

It would be more possible and likely to set up CO2/carbon capture devices to intake air and scrub out the CO2 in it. Some factories and power plants already do so. For automobiles, you could set up artificial trees along streets and highways, parks, etc.. to gather in and scrub CO2 from the air in metropolitan or urban areas. Having an onboard system on cars to capture and store CO2 would be too expensive and heavy since the chemical process of combustion creates around 20 pounds of CO2 for every gallon of non-ethanol blend gasoline burned...22 pounds for every gallon of diesel fuel. A gallon of gas weighs around 6 pounds...diesel around 7 pounds.

In addition, there are some thermo-electric designs being researched which can convert the excess and unused heat in gas or diesel engines, exhaust system//tailpipes into electric power for use in hybrid designs and improve the efficiency of cars and trucks, solar panels, etc..

"Turning waste heat into power

Taking advantage of quantum physics, a new way of harvesting waste heat and turning it into electrical power holds great promise for making cars, power plants, factories and solar panels more efficient"

........

""The effects we see are not unique to the molecules we used in our simulation," Bergfield said. "Any quantum-scale device where you have a cancellation of electric charge will do the trick, as long as there is a temperature difference. The greater the temperature difference, the more power you can generate."

Molecular thermoelectric devices could help solve an issue currently plaguing photovoltaic cells harvesting energy from sunlight.

"Solar panels get very hot and their efficiency goes down," Stafford said. "You could harvest some of that heat and use it to generate additional electricity while simultaneously cooling the panel and making its own photovoltaic process more efficient."

"With a very efficient thermoelectric device based on our design, you could power about 200 100-Watt light bulbs using the waste heat of an automobile," he said. "Put another way, one could increase the car's efficiency by well over 25 percent, which would be ideal for a hybrid since it already uses an electrical motor."

So, next time you watch a red sports car zip by, think of the hidden power of the electron and how much more efficient that sports car could be with a thermoelectric device wrapped around its exhaust pipe."

"The artificial tree developed by Lackner and Wright will also stand passively in the wind like a tree. But it will remove CO2 from the air faster and at far higher levels than natural photosynthesis can accomplish. The team envisions creating "forests" of these carbon-capturing trees to remove carbon from the atmosphere. The CO2 can then be released by a gentle flow of water, either to be used industrially or sequestered safely underground.

These units, Lackner says, will be roughly the size and production cost of a car, and collect about one ton a day of carbon from the air -- the equivalent of the greenhouse gases produced by 36 motor vehicles in a day. Ten million of these artificial trees, he estimates, would sop up 12 percent of the carbon that humans add to the atmosphere each year."

"At the moment, synthesizing fuels from CO2 would be a "marginally profitable" enterprise, Chichilnisky says, but she predicts that further research and development will continue to cut costs and eventually make them fully competitive with geological extraction. Other uses like carbonating beverages, synthesizing industrial-grade formic acid, producing dry ice, and a process called enhanced oil recovery (EOR) in which carbon dioxide is pumped into old oil wells as a solvent to scour lingering hard-to-get oil from the ground, are already up to speed.

EOR currently boosts U.S, oil output by 10 percent a year. Chichilnisky predicts that the EOR market will rise to over $800 billion over the course of the next decade, creating a hugely enhanced demand for captured CO2. The U.S. government estimates that state-of-the-art EOR with carbon dioxide could add 89 billion barrels of oil to the nation's recoverable oil resources. That's more than four times the country's proven reserves.

With demand for CO2 even at present levels far outstripping supply, and companies willing to pay $100 a ton to get a hold of it, the business prospects for carbon capture look bright."

What I mean is some sort of device that can be attached to exhaust pipes in vehicles, power plants, and other carbon emitting devices that will capture all the co2, so that we could still use fossil fuels, which are cheaper than wind and solar. Has someone already invented this?
