Surely they are not claiming having a solar panel integrated, as removing CO2 from the atmosphere, as that would be an outright lie.
- TaylorAlexander 4y ago“This Zem car has a pair of carbon filters in the front grille that contributes to cleaning the atmosphere by removing about 4.5lb of Carbon-dioxide per 20,000 miles.” It is not clear to me how these filters work but we can see they are not claiming the magic is in solar panels.
- fodkodrasz 4y agoThanks! Missed that part somehow.
- FooBarWidget 4y agoCarbon filter. Though I am confused. How can a passive filter remove CO2? Don't you need to add energy and use some sort of chemical reaction?
- magicalhippo 4y agoCertain compounds can react with the CO2 in air passively, eg sodium hydroxide[1]. AFAIK you're right that energy has to be put into creating those compounds, tho that can be provided by the sun. But yeah, overall a quite silly idea, like the solar roadway[2] type proposals.
