GE’s Electric Bus (Source: GE)
The Inspired Economist (IE) recently interviewed GE’s Bob King, a 30-year veteran of the company who has driven the company’s research in the advanced electric and hybrid vehicle space.
With the energy crisis of the late ’70s, GE began to aggressively pursue the development of an electric test vehicle, creating a prototype that included nearly all the components that can be found in today’s hybrid vehicles. Bob worked on this, and also on the development of GE’s hybrid bus in 1996. The bus established the emissions requirements for NYC’s hybrid transit buses and paved the way for those that you see on the roads today.
Bob has witnessed the cyclical nature of the country’s demand for energy-efficient cars and the changes in technology that have resulted in advancing the industry. Here’s what he had to say to IE.
IE: What is GE’s hybrid vehicle? Can you describe it? It’s USP?
BK: GE researchers are working on hybrid systems and battery technologies for a hybrid locomotive and for heavy-duty vehicle applications, which we believe could cascade down and help accelerate key advancements for Plug-in Hybrid Electric Vehicles (PHEVs) in the automotive sector. In fact, we also have been performing some research in conjunction with the lithium-ion battery maker A123Systems to support their battery development for automobile applications.

Editor’s Note: This is part three of an interview Tetsuya Yokoyama recently had the opportunity to conduct with Honda R&D Chief Engineer, Mr. Yamamoto, at Eco-Products 2008 in Tokyo, Japan. Mr. Yamamoto is greatly involved in the development of Honda’s hybrid technology including the upcoming 2009 Insight. Read part one here and part two here.

After talking with Mr. Yamamoto about supercapacitors, I moved on to discuss the possibility of a manual transmission on future hybrid vehicles. He said that it would not be difficult to put a manual transmission into an Integrated Motor Assist (IMA) Hybrid system.
Even though the current Civic hybrids have no option for a manual transmission, a manual transmission was offered on the first generation of that car. The reason the current Civic Hybrid has a continuously variable transmission (CVT) is to increase overall fuel efficiency by automatically letting the system choose the most efficient drive ratio.
While you could potentially get a much better fuel efficiency with a manual transmission if you practice “Ecodriving,” the efficiency would go down significantly if you choose lower gears more often or drove more aggressively.

Editor’s Note: This list represents the ten “best” electric and plug-in hybrid cars (as I see them) coming out in the next two years, but, after that initial culling, this list has been organized by release date, not preference.
With the onslaught of electric concepts and announcements coming out of the 2009 Detroit Auto Show, you’d think that the entire world is about to junk their old jalopies and rush out and buy electric cars tomorrow.
But, alas, as much as millions of Americans would love to pay 3 cents a mile on their daily commutes, our choices for electric cars are, at the moment, severely lacking.
Although the promise of the 2009 Detroit Auto Show reeks of desperation, it’s not all smoke and mirrors. Believe it or not, there are a bunch of noteworthy electric cars, both all-battery and extended range plug-ins, reaching US production sometime in the next two years.
So, if you’ve got the time to wait and you find yourself longing for the cheapest, quietest, and most earth-friendly commute you could imagine, take a gander at this list… electric bliss is closer than you probably thought.

As I mentioned in part one of my interview, Honda first introduced the ultracapacitor with the J-VX concept. The J-VX ultimately led to the original production Insight, without the ultracapacitor. Honda also used the ultracapacitor technology on the FCX models (pre-Clarity) for years.
Honda developed their original ultracapacitors, and improved them during the period of FCX development and explains more about it on their web site.

A newly-granted US patent (PDF) for the upcoming ultracapacitor technology from secretive Texas-based EEStor contains a ton of detailed information about their near-mythical Electrical Energy Storage Unit (EESU), which has the potential to revolutionize transportation and our energy infrastructure.
Apparently one EESU weighs 281 pounds, has a volume of 2.63 cubic feet, can be fully charged in 3-6 minutes, is completely unaffected by temperature, will not explode or catch fire in an accident, and provides 52 kWh of electricity (nearly the same amount of energy the Tesla Roadster battery can hold, which reportedly takes the Roadster about 240 miles).

Whatever you do, don’t call it a battery.
A research group at the University of Texas at Austin has taken a carbon-based nanomaterial called graphene, and developed it into a device that has the potential to vastly improve upon the energy storage capacity of batteries. Reportedly, graphene could also double the current maximum storage capacity of the group of battery alternatives known as ultracapacitors.
If the research group’s findings bear out when applied to reality, it could mean a complete phase change in the way we approach energizing not only our transportation sector, but our entire energy infrastructure.
