Earth911's Mitch Ratcliffe talks with Ideanomics CEO Alf Poor about the evolution of transportation. We need new systems for vehicle charging in public transportation and distribution,  more alternatives to cars, trucks, buses, motorcycles and scooters, as well as new approaches to paying for mobility. We may soon be paying just for the distance we travel while the vehicles we use become shared assets managed and maintained by companies that specialize in specific types of transportation. Ideanomics takes a holistic approach to solving these problems, creating companies to tackle a variety of the challenges we face as we reinvent our economy and transportation systems. It is a publicly traded company dedicated to reinventing transportation for sustainability — it trades on the NASDAQ under the symbol IDEX. Ideanomics has launched several companies, including Energica, a maker of performance electric motorcycles, commercial electric fleet operator Medici Motor Works, which is building trucks solutions for public transit and private distribution companies, Solectrac,  the first American manufacturer of electric tractors, Treelectrik, a Malaysian electric scooter maker,  and Wave, a contactless charging solution for electric vehicles and other sustainability-oriented companies around the globe.
