Enough with this stupid argument! The problem with EVs is that we have a dirty electric power industry? You could say the same thing about vacuum cleaners and microwave ovens! A dirty electric power industry is a problem that needs fixing regardless of what you plug into the wall. And don't minimize the impact of gasoline - it's far from just what comes out of the tailpipe: unconventional petroleum production and refining to gasoline has a very high energy cost where it takes 5 times as much energy to get it to the pump than you get when you buy it and then convert it inefficiently into kinetic energy. Even if you use dirty electricity, unless you drive a very good hybrid, the environmental footprint of your driving an IC vehicle is higher than a comparable EV. The only thing missing is a full size EV pickup truck for commuting American style.
Fritz - forgot to respond to your second question. Tesla Motors is working on a supercharger network (which is actually free to Tesla owners) that will recharge their 300-mile ranged car to 80% of the battery within a 1/2 hour.
In my area in Florida (Florida Power and Light) we burn NO coal. 87% is natural gas and nuclear.
As a PHEV driver, I love the argument that federally regulated stationary stacks are worse than millions of mobile tailpipes burning a limited resourse, oil.
What about 0-60 in under 4 seconds says underpowered? The fastest IC car under $50K does 0-60 in 4.4 seconds while the fastest of all costs $2.4M. Cost for this level of performance just isn't an issue. Look for more split hybrid vehicles with independant electric direct drive at the wheels - torque at the wheels has a big advantage over torque into a transmission and independant control gives much better steerability. Also, brake fade is much lower. 0-60 doesn't tell all of the story though: vehicles with independent electric drive clean up on the serpentine. On a high performance car, it's relativley easy to add 100+ HP to each of the front wheels with a motor/brake module. While hauling around a battery isn't much joy, it does provide good distributed weight and low center of gravity for traction and stability in a way that's just not possible with a monster V8.
When are we going to address the entire energy problem. In lieu of oil we will be burning coal, whose carcinogenic and radiation effects far exceed those of nuclear power.
P.S. 0-60 mph in under ten seconds is not the only criteria for judging speed. And let us not forget the 6 to 8 hour rest stop required after a 100 mile leg of your trip.
To add to the comment about lackluster sales of HEVs and Electrics:
I think the sales of HEVs and Electrics is purely based on desire of the company to promote it properly. The Prius has gone from a single model, to a family of models. This is because they advertise the model properly, and you can walk into a Toyota Dealer and walk out with one the same day. Americans want it here and now, and if they walk into a dealership and are told they can have it in 3 or 6 months, you will lose the sale most of the time. It is a system adopted by the American Companies, that is DESIGNED to fail, and yet... people ARE buying and waiting for them. Imagine if they were available for purchase THAT DAY!
It looks like naperlou strikes out with the statement that most of these cars are small and underpowered... and to relate that to the sale of electric and hybrid cars makes little sense. The people that read the blurbs at the bottom clearly saw the incredible speed and power of some of the vehicles. Others, that push the boundries of distance use less power and get lighter. You think a Chevy volt or the BMW and many other HEVs and Electrics would disagree vehemently that these cars are underpowered. Electric car technology is the future of car design, and this show proves it. There will be many ways to get the electricity to run the cars, but the simplicity of electric will lead to less expensive cars that just don't have the kind of breakdowns, failures and maintenance costs of ICE based autos. For now, we will continue to stick ICE engines in them to increase distance issues, until we find better ways to store the power we need, even though many Americans work within the range of available electrics.
Rob, we are already there. I'd venture to guess that Europe will be leading the "charge" in this arena since their standard electricity is already 240 volt. There is no question about performance. Look at this month's Motor Trend and see how the Tesla S Faired with the Porsche, BMW M5, and Mercedes 100k cars.
Hard for me to believe anyone would mention "underpowered" as these cars are hitting 0-60 in under 4 seconds.
Whether you want to believe it or not, EVs are HERE to stay this time!
Chuck, with all of these new electric vehicles showing up, we may be headed toward tipping point where charging issues, battery technology, and weight begin to get mastered.
For 3D printing to make the jump from rapid prototyping to manufacturing, engineers will need to find easier ways to move products from their CAD screens to their printers.
Gigabit and PoE are two networking technologies moving ahead in tandem as industrial users power remote Ethernet devices such as IP security cameras at 1,000 Mbps over existing CAT5 cable.
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.
