Stations able to dispense hydrogen, like this one in Warsaw, are increasing in number in Europe, North America, and Asia.Photo: iStockphoto

You’d have to be completely uninterested in cars or any other type of transportation to not recognize that automobiles are undergoing a major transition. They no longer run solely on internal-combustion engines and burn petroleum-based fuels. Nowadays, consumers routinely purchase vehicles that run in part or entirely on electricity.

iRobot CEO Colin Angle on Data Privacy and Robots in the Home

In light of Amazon's recent acquisition, we revisit our 7 September 2017 Q&A with iRobot's CEO

Editor's note: Last week, Amazon announced that it was acquiring iRobot for $1.7 billion, prompting questions about how iRobot's camera-equipped robot vacuums will protect the data that they collect about your home. In September of 2017, we spoke with iRobot CEO Colin Angle about iRobot's approach to data privacy, directly addressing many similar concerns. "The views expressed in the Q&A from 2017 remain true," iRobot told us. "Over the past several years, iRobot has continued to do more to strengthen, and clearly define, its stance on privacy and security. It’s important to note that iRobot takes product security and customer privacy very seriously. We know our customers invite us into their most personal spaces—their homes—because they trust that our products will help them do more. We take that trust seriously."

New EV Prototype Leaves Range Anxiety in the Dust

Mercedes-Benz’s Vision EQXX completed a record-breaking 747-mile run in May

The Mercedes-Benz Vision EQXX

Not long ago, a 300-mile range seemed like a healthy target for electric cars. More recently, the 520-mile (837-kilometer) Lucid Air became the world’s longest-range EV. But that record may not stand for long.

The Mercedes-Benz Vision EQXX, and its showroom-bound tech, looks to banish range anxiety for good: In April, the sleek prototype sedan completed a 621-mile (1,000-km) trek through the Alps from Mercedes’s Sindelfingen facility to the Côte d’Azur in Cassis, France, with battery juice to spare. It built on that feat in late May, when the prototype covered a world-beating, bladder-busting 747 miles (1,202 km) in a run from Germany to the Formula One circuit in Silverstone, England.

A Multiphysics Approach to Designing Fuel Cells for Electric Vehicles

White paper on fuel cell modeling and simulation

Fuel cell electric vehicles (FCEVs) often reach higher energy density and exhibit greater efficiency than battery EVs; however, they also have high manufacturing costs, limited service life, and relatively low power density.

Modeling and simulation can improve fuel cell design and optimize EV performance. Learn more in this white paper.
