First never believe anything Pike says as they are mostly wrong. Not sure who is paying them off or if they are just incompendent. Likely getting paid to give a customers viewpoint/bias.
Next as an EV designer, builder and driver one should never design a larger battery pack without cooling. Cars get 60C just sitting in the summer sun turned off. Just ask anyone in the south.
EV's shouldn't have more than 100-150 mile range as after that a ICE generator is far more cost effective and gives unlimited range. All my EV's have or will have a 40lb generator giving unlimitede range. 80 mile range is probably the sweet spot.
A123's have so little resistance they put out huge amounts if specific power with little heat generation. I agree this is just a small improvement mostly gained by higher battery weight/kwhr. This means more material though as they said, Iron, alum, Lithium, plastic, etc is cheap with most under $4/lb and averaging about $6/lb. Most Lithium batts are about 22 lbs so it's just not that costly.
I buy complete A123 battery pack systems/BMS, etc for about $700/kwhr custom made from cylinder cells that can and has done 170mph and 7.9sec 1/4 mile though that was recently broken to 200mph and 6.9sec EV IIRC.
Beth, you are right there. Time is an issue. It takes time to prove a technology does in practice what it does in the lab. I think they have something here, and it is a good trend. Let's see if investors think so too.
On paper, or maybe even in limited testing, it seems like A123 has made a big leap with its lithium-ion cells in terms of reducing cooling requirements. Nevertheless, there is still a lot of skepticism that the company will have to over come. Commercializing these efforts will take a lot of time and money, which is something A123 and its battery maker competitors don't necessarily have.
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
