Technically, combustion cars already do that because the air in the combustion chamber must be ideally free from any contaminants - they just add other pollutants via the tailpipe.
I think it's a neat and relatively cheap way to deal with this problem in EVs - existing radiator fans are more than enough for this task.
- stephen_g 4y agoThat’s actually an fascinating idea. From the page it looks like it just sucks in from the front grill, I wonder if it could suck from the wheel wells too, to grab brake dust at the source?
- Szpadel 4y agoisn't it going to hurt range? I think radiator intake is ones of things that are not very aerodynamic, but are necessary evil for combustion cars. Also I think break dust is not that big deal as in EVs that's just "emergency" breathing method as you want to use regenerative breaking when possible
- frosted-flakes 4y agoHow would that work with dirt roads? It seems like the filter would get clogged in no time at all.
- Tade0 4y agoIt's the same principle(and scale) as an air intake filter in a combustion car. Since you can drive a such car on a dirt road, this shouldn't be a problem.
