Sure, electric cars don’t burn gas, but their electricity has to come from somewhere and in many parts of the country, that means coal. Surprisingly though, even accounting for that, an electric car still produces less global warming emissions than a gasoline powered car getting 27mpg, according to a new study. Of course, 100% coal-sourced electricity is a truly worst case scenario, as natural gas, nuclear, and renewable sources also come into play. Taking that into account, it turns out that about 45% of Americans live in places where the electric car emissions are equivalent to a 50mpg automobile! 37% have the equivalent of a 41-50mpg car, and 18% have a 31-40mpg equivalent.

The bottom line is, yes, electric cars still result in air pollution and global warming gas emissions, but they’re still far better than almost any car on the road today (the one exception I can think of being VW’s fantastic TDI diesel engine). More importantly, as more renewable energy is plugged in to the grid, electric cars will continue to improve, and quickly outpace even VW’s best diesel efforts.

I use the word ‘car’ loosely here. This four wheeled contraption, the Volpe, is like no other car you’ve seen (well, apart from the Peel P50 with which is shares more than a passing resemblance!). It’s a two seat four wheeled car, powered by an electric motor with a natural gas or gasoline generator providing extended range capability.

The seating is tandem style, and if you look at the image you can see how this would be a great setup for a rear passenger that has no legs. So, let’s be realistic here and call it a single seat car.

Why would you want one? Well, efficiency for starters…being so small, electricity usage is small as well. Parking is a cinch. It’s even small enough to find some creative parking places, like inside (it’ll fit inside an elevator). It could actually make for a decent commute vehicle in large cities, as long as you can avoid freeways and other faster roads.

As mentioned previously, the Peel P50 was actually first with this ‘mini car’ idea, and my favorite TV show, Top Gear, had a great review that shows this car in real life, check it out below. I expect driving a Volpe around town would have similar advantages…and drawbacks (the Peel P50 is smaller, though).

Specialized Bicycles has unveiled a new electric-assist bicycle, the Turbo. Like other e-bikes, it uses an electric motor to supplement normal pedaling, offering both higher top speed and increased range. In this case though, it’s that top speed that’s a bit of a problem. It seems the aptly-named Turbo is just too fast to be legal in many places (like the US), topping out around 28mph. So for now, availability is limited to some areas of Europe, but it also seems that a simple design tweak could reduce its top speed to a more legal level for broader appeal.

More pictures can be found here, or check out the video below.

When I saw this eBike concept from Frog Design, my initial reaction was, look at all that wasted space in the middle section where a larger battery could reside. It’s a trap I fall into sometimes…trying to optimize any design for function and performance, while ignoring what is perhaps the most important element of any product design.

Emotion.

That center void in the bike concept? It looks cool and creates flowing curves, further enhanced through the use of materials, colors, and illumination (check out some of the other pictures for that). The emotional attachment between a consumer and the product is absolutely critical. Not to say that technical performance isn’t, but you can’t have one without the other. Apple’s iPads and iPhones are great examples of that, where the form factor and graphical user interface create a welcoming experience for the user and ultimately a very successful product.

With the miniaturization of technology, more and more emphasis will be placed on the emotional side of design. I mean, who wouldn’t want to own a lightcycle if given the chance!

With gas prices rising and expected to continue to do so for, well the rest of our existence, alternative forms of transportation are becoming more and more appealing. Electric bicycles are one option that offer some great functionality with few compromises. Towards the higher end of the spectrum is this $6k PiCycle Limited bicycle from Pi Mobility, which offers a 35-45 mile range at 30mph. Sure, it’s pricey for a bicycle, but when you view it as more of a replacement for a car, it becomes incredibly attractive, especially when you consider the very low maintenance cost and low energy costs.

They also made a cool commercial for this, check it out after the jump below.
