I'm definitely up for anything that can reduce the cost of truck emissions as on my way to work there is a particular roundabout which almost always as big trucks and sometimes the area just seems like a spot where it's more difficult to breathe, while I hope this is the solution there may still be a easier way's as it seems like there maybe alot of set-up, wiring and costs involved for these to be places on our many highways and if trucks are using it why not buses etc.
