Ask the Best and Brightest: WTH is a HHV?
You gotta sit up and take notice when a new technology claims a 40 to 50 percent increase in fuel economy. Either that or hide your checkbook. Personally, professionally, I’ve never heard of a hydraulic hybrid vehicle (HHV), never mind a diesel hydraulic hybrid vehicle (DHHV?). But IndustryWeek has, as well as the United Parcel Service, which plans to deploy a fleet of two (count ’em two) HHVs in Minneapolis early next year. The only explanation for the taxpayer-funded technology involved is, to say the least, literally, marginal. “The technology, originally developed in a federal laboratory of the Environmental Protection Agency, stores energy by compressing hydraulic fluid under pressure in a large chamber.” Does one of our Best and Brightest care to elaborate? Meanwhile, it’s kinda weird to hear our government officials talk about the hybrid premium: “The EPA estimates that when manufactured in high volume, the added costs of the hybrid components can be recouped in less than three years through lower fuel and brake maintenance costs.” [thanks to nutbags for the link]
