Neat! It's interesting how starting with small-scale applications can work better than the theoretically more-efficient stationary applications, because you can iterate and mass-produce.

How much of a problem are things in the exhaust like sulfur and particulates? Do they end up poisoning or clogging the adsorber after some time, or does regeneration burn them off? Could you remove some of the particulates from the exhaust to save our lungs too?

Our adsorbent actually captures the CO, NOx, and SOx in vehicle exhaust, so we'll be taking those out of the air in addition to CO2! Any particulate matter that makes it through the diesel particulate filter will cake onto our adsorbent, which we believe actually makes it more effective, so we'll be taking that out of circulation as well.

Are those impurities an issue when reselling the CO2?

They aren't - concrete producers, chemical producers, and many other end users actually only need CO2 that's > 90% pure, a bar that we'll very easily clear.
