Beth, the technology does go back more than 100 years. My grandmother had an electric car in 1909 that she liked very much. It would take her to church, a friend's house, to the store and home again. No steering wheel, it had a lever that you could turn to the right or the left to steer. It had to be charged frequently.
Since then battery technology and electric motors have been improved but you still need a power plant to charge it and batteries still are not as efficient in extremely cold weather or the heat of summer. Just try to start your SUV in a sub zero winter with a weak batter. Most of the range stats are based on level ground. Electric cars don't do as well on hills.
A gas/electric hybrid car would be better because the gasoline motor can generate all or part of the electricity.
Electric vehicles go a LOT further back than that! Try way over ONE HUNDRED years ago. Some of the earliest cars were all-electric. There's a full site dedicated to this on Wikipedia. They didn't last very long because of the same issues they face today: limited range, lack of supporting infrastructure, and costs.
Nice under-the-covers snapshot of the component and architectural evolution of these electric and alternative power train vehicles. I didn't realize how far back some of the early development goes. Seeing old-fashioned looking cars from the late 60s and 70s that have a so-called electric or hybrid heritage is quite surprising.
As energy efficiency becomes more and more a concern for makers of electronics devices, researchers are coming up with new ways to harvest energy from sound vibration, footsteps, and even electromagnetic fields in the air.
The government wants to study your brain, and DARPA wants to use similar information to give robots true autonomy beyond any artificial intelligence developed to date. Sound like science fiction? It's not.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
