Imagine the commercial delivery truck of the future — powered by a silent electric engine and emitting fresher air than it takes in. Now keep imagining, because for the next few decades, the reality is that roads will more likely be dominated by the same internal-combustion vehicles our grandparents drove.

In the meantime, Achates Power has revisited a century-old concept of how to remake the internal combustion automobile engine so it’s cheaper, has fewer emissions and uses less fuel. It may not be the future you imagined, but sometimes the best new ideas are actually old ones.
