Editor’s Note: This is part four of an exclusive sit down I had with Hideaki Watanabe, Nissan’s Division Manager of their Global Zero Emission Business Unit, at last week’s U.S. debut of the LEAF in Los Angeles. Part one is devoted to battery swapping, part two to battery leasing, and part three to the quietness and safety of EVs.

During the Frankfurt Motor Show in September, Renault invited Gas 2.0’s own UK-based Chris Milton to an exclusive event detailing the company’s electric car strategy. The event introduced some rather quirky (and quirkily named) electric cars, including the Twizy, the Kangoo, and the Zoe. These aren’t just concept cars, they are cars that Renault intends to build and sell—some by next year.

Based on those releases—and the fact that Nissan hasn’t invested anything in battery swapping while Renault has jumped in head first—it started to seem that the Renault-Nissan Alliance was taking two completely different paths on the road to EV world domination. On the one hand you have Nissan with the rather mainstream-looking LEAF and plans for a luxury Infiniti electric car. And on the other you have… the Twizy.

In my recent sit down with Hideaki Watanabe, Nissan’s Division Manager of their Global Zero Emission Business Unit, I asked him to explain why Nissan and Renault were apparently moving in opposite directions.

How did a woman who the Securities and Exchange Commission says planned one of the largest accounting frauds in US history end up as Chief Financial Officer of Aptera Motors?

It’s just one of many questions swirling around what appears to be a meltdown in progress at the beleaguered manufacturer of safe, hyper-efficient electric vehicles (see the posts here, and here if you don’t know what’s going on).

When a business is running smoothly, there are strong incentives for everyone to be a team player and hide any signs of internal strife. However, as the rate of layoffs and “vacations” has increased over at Aptera, so has the potential for leaks. And sometimes a simple name can take you places you never thought you’d go.

The new site—driveclean.ca.gov—offers well-organized data that ranks vehicles according to various emission and cost characteristics and provides tools to compare models on a variety of qualities, including the new incentives that low carbon emission vehicles qualify for: up to $5,000 for cars, and up to $15,000 for electric trucks or vans.

One aspect of the site is revolutionary: For the first time Americans will be able to compare models based on how many grams of CO2 each spews per mile.

It’s been known for a long time that the emissions from coal are harmful, both to the environment and human health. Yet, because it’s so plentiful, the U.S. still gets the majority of its electricity from coal-fired power. With the world focused on increasing the use of plug-in cars, where we get our future electricity becomes a key question.

Yesterday, a medical report was released, “Coal’s Assault on Human Health,” highlighting the dangers of coal, by the Physicians for Social Responsibility. Other study participants included the American Lung Association and the American Nurses Association.

Editor’s Note: This is part three of an exclusive sit down I had with Hideaki Watanabe, Nissan’s Division Manager of their Global Zero Emission Business Unit, at last week’s U.S. debut of the LEAF in Los Angeles. Part one is devoted to battery swapping, part two to battery leasing, and part four to the different zero emissions directions of Renault and Nissan within their alliance.

Nissan CEO Carlos Ghosn made it a point to highlight how quiet the upcoming Nissan LEAF electric car will be during an event in Los Angeles last week to mark the car’s U.S. debut. “LEAF has no engine, no tailpipe, no fuel tanks,” he remarked. “As a result LEAF has zero carbon emissions, zero particle [emissions] and zero noise. It’s quiet and clean.”

The gathering crowd of electric car makers has been drumming this “quiet mantra” since day one, and, indeed, it is certainly a great selling point. But recently the quietness of EVs has come under scrutiny as a potential safety hazard to the blind, the elderly, and children; if you can’t hear the car, it’s one less warning you have of an impending accident.

Just how popular is the Prius? If you ask Jim Lentz, President of Toyota’s U.S. arm, it is so popular that it could soon sell even more units than Toyota’s perennial best seller, the Camry. Are hybrid cars really that popular?

To date, Toyota has sold two Camrys for every one Prius, but with over a million of the peppy little hybrids sold, and sales growing stronger every year, the Prius may soon join the Camry on the podium of top sellers.

Here’s a transformer idea for city messenger services from design student Adam Schacter. This tiny EV would carry small cargo loads efficiently in its upright mode. In that configuration, the vehicle would be able to fit three to a parking space. But for days when you had a larger load, you’d simply flip down the back and pull it out wider to become a little pickup truck. Even flipped down into a truck, it would fit two to a parking space.

As the fastest land animal on Earth, the cheetah is a beast often referred to in metaphors, and studied for its movements. Humans, as you may have noticed, have something of an obsession with speed. Many of us won’t give up that obsession, no matter how much climate change may endanger our future. Did I mention humans are stubborn as well?

Thus the quest for a fossil fuel free future brings about a lot of interesting, outlandish, and outright weird ideas. This one is one of the weirdest, and yet it may actually have a future of sorts. Its a tricycle designed to mimic the movement of a cheetah… and, apparently, it works.

Move over CO2—you’ve been ousted, along with methane, as the biggest offenders of global climate change. According to a new a study by Purdue University and NASA, the major chemicals most frequently cited as leading to climate change, namely carbon dioxide and methane, are actually outclassed in their warming potential by compounds receiving less attention. The majority of “greenhouse gases” are created by humans.

The results were discovered when researchers studied more than a dozen chemicals, or greenhouse gases as classified by their warming properties defined by the Intergovernmental Panel on Climate Change. From there, the team developed a blueprint for the underlying molecular machinery of global warming. The results appeared in the November 12, 2009 issue of the American Chemical Society’s Journal of Physical Chemistry, just in time for the convergence of world leaders in Copenhagen.

Update 11/19/2009, 9:00 AM Pacific Time: According to Th!nk’s Twitter feed, Indiana has not been officially chosen, saying “We’re moving toward completing our US site selection — but it will take another week or two to finalize the location. Stay tuned…” Apparently other states, such as Oregon, are still in the running. Whether this is a genius marketing ploy to increase interest, or simply a misstep by Ener1, we’ll have to wait and see.

Norwegian electric car maker, Th!nk, has seen some rough financial patches as of late—having gone through a bankruptcy and restructuring—but they seem to be clawing their way back to relevance these days. With a long wait list and more demand for the Th!nk City than they can meet in Europe, think has once again turned their eyes on the U.S. market.
