With Tesla IPO, Has the Age of Electric Vehicles Arrived?

Tesla Motors will have its IPO today. The Nissan LEAF electric vehicle sold out shortly after it was announced, many of the orders coming from first-time Nissan customers. The Chevy Volt may even hit the showroom later this year.

It certainly seems as if the age of the electric car is upon us. But hold on a minute. Let not all the hype keep us from seeing the speedbumps -- and maybe a few roadblocks in the way of a complete transition on our roadways.

Don't get me wrong, I believe the battery electric vehicle (or BEV for short) is the vehicle of the future. But this new generation of electric vehicles will have lots of challenges, including battery technology, range, and charging.

Let's take range. Today, we are used to driving 300 miles or so before having to pull into a gas station and, after inserting our credit card, choosing the grade, and popping the nozzle in the tank, we can be refueled and ready to go before we've had a chance to clean the windshield.

Contrast that with the currently planned charging experience for electric vehicles. Drive 100 miles and you need to charge it -- the LEAF will take 8 hours for a full charge at 200 volts -- and there is currently very little infrastructure to support electric vehicle charging.

You can get around this by increasing the number or density of batteries in a vehicle, which will add weight and cost, but as battery technology improves the weight and cost, life and range will increase.

Charging, however, still remains an issue. I'm concerned about the vision of the future that imagines hundreds of thousands of charging stations around the country, in cities, parking garages, and on-the-street parking (perhaps replacing the meters that have gone the way of the parking kiosk). That seems like an awful lot of infrastructure needing to be built.

And what about that volatile mix of bad weather and high voltage. Imagine the housewife, parking in the Whole Foods lot, plugging in while she goes in for groceries. She comes out, and some idiot parking next to her has dislodged the plug. Not only does she not have the charge she needs to go pick up Junior from day care, but now she's dealing with a live wire on a wet macadam. Doesn't sound like the way to go to me.

I've even seen plans for "battery replacement stations" where you drive in and your old battery is swapped out for a new one -- the batteries are on a huge circular conveyor. The Pep Boys, Manny, Moe, and Jack, are probably salivating at that prospect. But that doesn't seem feasible to me.

Which is why I was encouraged by this video from the UK-based HaloIPT of an alternative future featuring wireless, dynamic charging based upon inductive power transfer technology.



Momentum Dynamics, a Malvern, PA-based company I've written about before on this blog, also has a technology that may help advance the vision depicted above.

As Andy Daga, CEO of Momentum Dynamics said to me recently, the battery electric vehicle industry "Needs three things: improved battery technology (this is coming), improved vehicle integration of new technologies (also in the works), and finally, improvements in the technology and distribution of charging technology."

Of course, that is what Andy and his company are focused on, and which he feels "is absolutely critical to the industry."

I hope for the sake of the electric vehicle market that the Tesla IPO ($TSLA) goes well. I have concerns that, like $AONE, it will go from 0 to 60 and come to a screeching halt, like, well, a Tesla Roadster as it approaches a speed trap. (That won't be good for future cleantech IPOs -- some companies have already pulled their plans this year).

But I have larger concerns that we are ignoring the looming issues facing the electric vehicle industry that may well prevent it from going the distance.

Wallstrip on Oil and Gas Prices: They've Got Us Over a Barrel

Our minivan now cost over $70 to fill. We don't even drive it that much, but it still hurts.

Here's a Wallstrip "Julie in the Street" episode on oil and gas prices in New York. I'm with Julie, don't know whether to laugh or cry:



The saddest (but truest) comment is the Brit who says he'd pay whatever it takes for a gallon of petrol and just have to do without something else. OPEC take note!

Global Climate Change: EPA Tells States "No, No, No" On Own Auto Emissions Standards

The US Environmental Protection Agency (EPA) rejected the rights of California and 16 other states to set their own standards for carbon dioxide emissions from automobiles.

Claiming federal authority, EPA administrator, Stephen L. Johnson, said the proposed California rules are made moot by the energy bill (HR6) signed into law by President Bush on Wednesday.

According the the New York Times, "The decision immediately provoked a heated debate over its scientific basis and whether political pressure was applied by the automobile industry to help it escape the proposed California regulations. Officials from the states and numerous environmental groups vowed to sue to overturn the edict."

Johnson was quick to defend his agency's decision, stating, "The Bush administration is moving forward with a clear national solution, not a confusing patchwork of state rules. I believe this is a better approach than if individual states were to act alone."

For over two years California, New York, New Jersey, and Connecticut, along with 13 other states have waited as the Bush administration debated the issue of a state's right to adopt stricter air quality standards than the federal government.

The emissions standards California represented GHG emissions cut of 30 percent in new cars and light trucks by 2016, beginning with 2009 models. That's significantly higher -- 43 miles per gallon for cars and some light trucks and about 27 miles per gallon for heavier trucks and SUVs -- than the Energy Bill's 35 MPG.

I always find it interesting that state's rights are evoked inconsistently when its convenient. One wonders whether the Bush administration simply didn't want to be trumped by Schwarzenegger.

"It is disappointing that the federal government is standing in our way and ignoring the will of tens of millions of people across the nation," Mr. Schwarzenegger said. "We will continue to fight this battle."

You can almost hear him say, "I'll be back..."

Energy: House Sends Bush Energy Bill to Sign

President Bush is to sign a compromise Energy Bill (HR6) this morning, which will help reduce US dependence on foreign oil and scratch the surface on climate change impacts by cutting about a quarter of greenhouse gas emissions that scientists say the US must slash.

Highlights of the Bill:

-New auto fleets must average 35 miles/gallon by 2020 -- a 40 percent increase in fuel-efficiency standards

-Mandate use of 36 billion gallons/year of ethanol and other biofuels by 2022, a six-fold increase over today's ethanol production.

-Phase-out conventional incandescent light bulbs by mid-teens, replaced with CFs and LEDs.

Those of us interested in alternative energy development were disappointed by the failure of congressional supporters to roll back US$13.5 billion in tax breaks for oil companies. The savings were to be used to create incentives for wind, solar and biomass energy development, as well as energy conservation.

The Bill actually represents the first increase in auto fuel economy since 1975 and the compromises made on both sides represents a true bi-partisan effort. So the House, Senate, and President Bush should be applauded for making this happen.

Innovation: Design for the Other 90 Percent


I'm looking forward to getting to New York to see the Cooper-Hewitt's "Design for the Other 90%" show, which runs through September 2007. The show features many of the design solutions, such as the Life Straw and others, that we've featured in the past in The Green Skeptic.

The brainchild of curator Cynthia E. Smith, Design for the Other 90% opened in May and will close on 23 September.

Here are some excerpts from the exhibition web site:

Of the world’s total population of 6.5 billion, 5.8 billion people, or 90%, have little or no access to most of the products and services many of us take for granted...Design for the Other 90% explores a growing movement among designers to design low-cost solutions for this “other 90%.”

...Designers, engineers, students and professors, architects, and social entrepreneurs from all over the globe are devising cost-effective ways to increase access to food and water, energy, education, healthcare, revenue-generating activities, and affordable transportation for those who most need them...

...More recently, designers are working directly with end users of their products, emphasizing co-creation to respond to their needs. Many of these projects employ market principles for income generation as a way out of poverty. Poor rural farmers become micro-entrepreneurs, while cottage industries emerge in more urban areas...

Some designs are patented to control the quality of their important breakthroughs, while others are open source in nature to allow for easier dissemination and adaptation, locally and internationally.

Encompassing a broad set of modern social and economic concerns, these design innovations often support responsible, sustainable economic policy. They help, rather than exploit, poorer economies; minimize environmental impact; increase social inclusion; improve healthcare at all levels; and advance the quality and accessibility of education.

...Design for the Other 90% demonstrates how design can be a dynamic force in saving and transforming lives, at home and around the world.

Global Climate Change: Big (Green) Apple, Taxis Go Hybrid

Nothing says New York like a Yellow Cab, but soon the yellow cabs will turn green under a plan unveiled by NYC Mayor Michael Bllomberg yesterday.

Bloomberg plans to put 1,000 hybrid taxis on NYC streets by the fall of 2008 and replace the remaining 13,000 taxi fleet with hybrids by 2012.

Bloomberg estimates the plan will save cab drivers more than $10,000 a year in gas and other expenses.

The Big Apple is turning green.
