Integration of data AND business process empower freedom of choice in a concrete technology ecosystem. The Walt Disney Co. is a world champion of vertical capture. The company’s theme parks offer families a complete package of entertainment, dining and lodging. Yet in Orlando, Fla., many visitors choose to complement or even skip Disney World for other cool things like Comcast’s…
Read MoreResearch findings make emissions case for diesel vs. electric truck power
A new study that evaluates several approaches to reducing greenhouse gas (GHG) and other emissions from medium- and heavy-duty vehicles over the next decade finds considerable advantages with advanced diesel technology—particularly when using renewable biofuels—as compared to an electrification strategy. Trucks operating in 10 Northeastern states (Connecticut, Delaware, Massachusetts, Maryland, Maine, New Jersey, New York, Pennsylvania, Rhode Island, and Vermont)…
