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.
New versions of BASF's Ecovio line are both compostable and designed for either injection molding or thermoforming. These combinations are becoming more common for the single-use bioplastics used in food service and food packaging applications, but are still not widely available.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This radio show will show what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
