I believe the joy stick would be the 2013 equivalent of a tiller.
The speed and range specifications and refueling times for Hydrogen Fuel Cells certainly seem more practical than the all electric vehicles. The explosion risk is always there with hydrogen. I think development of a large scale hydrogen infrastructure would be the hardest thing to overcome. It is very hard to store.
The caption of slide 6 states one mile per kg of gasoline is considered equivalent to 1 mpg. Since a gallon of gasoline is approximately 13.3 kg, this does not seem to make sense. Is this a misprint or am I missing something?
What about the "BOOM" factor of carrying around a substance that is know to blow up space shuttles? Drivers do not seem to be getting any better at driving, even with the advancments in safety technology!
Bloom Energy corporation has been producing fuel cells using methane a.k.a. natural gas or CH4 for fixed installation as commercial building power sources for a few years now. Lesley Stahl did a piece on 60 Minutes about them. A link to their website appears below:
It shouldn't be a problem to scale the technology down for either home or mobile use.
While it doesn't completely eliminate carbon from the fuel cycle, the higher efficiency of fuel cells versus internal combustion engines drastically reduces the carbon footprint and my understanding is that the cell chemisty used can be adapted to hydrogen fuel without too much trouble.
There was a lot research being done on Fuel cells using natural has there been any progress made? With all the sources of NG this could be used right away! PS what happens to the small amount of carbon when NG or propane is run through a fuel cell?
A joystick! interesting. I can't even imagine how that would work. Of course it would take some getting used to, but it could be more comfortable, easier and more responsive than a wheel. I guess that's the point?
Liz, I was particularly intrigued by the Roadster buggy's use of drive-by-wire technology. It has a joystick instead of a steering wheel. For years, engineers have told us that drive-by-wire allows us to do away with the steering wheel and replace it with a joystick or some othr device. Well, here it is.
Siemens and Georgia Institute of Technology are partnering to address limitations in the current additive manufacturing design-to-production chain in an applied research project as part of the federally backed America Makes program.
Most of the new 3D printers and 3D printing technologies in this crop are breaking some boundaries, whether it's build volume-per-dollar ratios, multimaterials printing techniques, or new materials types.
Independent science safety company Underwriters Laboratories is providing new guidance for manufacturers about how to follow the latest IEC standards for implementing safety features in programmable logic controllers.
