There's no doubt that the word "hydrogen" has a fear factor associated with it. But experts have pointed to additional issues with hydrogen fuel cells. At a recent UBM-sponsored panel discussion at the Embedded Systems Conference, experts cited three issues with fuel cells: outgassing, storage and infrastructure. But I think much of the problem comes down to this: In a sense, we've all been spoiled. Gasoline-burning cars are marvelous machines and they've raised our expectations so high that it's difficult for any new technology to come in and match up. Automakers are now tasked with satisfying incredibly high consumer expectations. If they don't build reliable machines, they'll be rightfully flooded with complaints from people who've invested $30K or $40K in their shiny new vehicles.
The plethora of ongoing engineering challenges with electric vehicles -- specifically, the cost of batteries (as discussed in this article) and their apparent vulnerability to fires) -- makes me wonder why fuel-cell vehicles are completely off the table. Only two years ago, Honda and several other automakers demoed hydrogen fuel-cell cars at major auto shows. These are ready to go; the big impediment is a complete lack of infrastructure. I still don't get why these vehicles have been ignored. It's a workable, safe technology. Maybe the word "hydrogen" scares people.
Kind of a sobering post, Chuck, but very enlightening. Based on what you outlined, it seems likely that refining Li-ion batteries and cooling system designs are likely only to deliver incremental benefits in terms of lowering costs--not nearly enough to move the bar in terms of sparking sales. As far as developing alternatives to Li-ion batteries, that seems like a long way off. It would be a shame to lose ground given how far we've come in the last five years in terms of wannabe acceptance of the EV as a mainstream vehicle.
Altair has released an update of its HyperWorks computer-aided engineering simulation suite that includes new features focusing on four key areas of product design: performance optimization, lightweight design, lead-time reduction, and new technologies.
At IMTS last week, Stratasys introduced two new multi-materials PolyJet 3D printers, plus a new UV-resistant material for its FDM production 3D printers. They can be used in making jigs and fixtures, as well as prototypes and small runs of production parts.
In a line of ultra-futuristic projects, DARPA is developing a brain microchip that will help heal the bodies and minds of soldiers. A final product is far off, but preliminary chips are already being tested.
