On NPR's Science Friday today Ira Flatow talked about the Chevrolet Volt and the Nissan LEAF, comparing and contrasting the two soon-to-be-released vehicles.  Phil Ross (editor at IEEE Spectrum) joined him in the studio as well as Nick Perry from Nissan and Tony Posawatz from the Chevrolet.

Ira Flatow asks, is the wait for EVs over?  Would you buy one?  Are they safe? How long do you have to wait to get one? What kind of plug-in do you want to see?

Nationally, for the demand for these vehicles as reported by Nick Perry & Tony Posawatz:

  • 18,000 Nissan LEAFS reserved
  • Chevrolet cannot comment yet on the specifics of how many Volts are in demand, but Tony says its "overwhelming"
  • Over 12,000 public charging stations in the ground this Fall, nationwide (19 states)
  • Chevrolet aims to be manufacturing the Volt in the US and exporting it to China by 2020
  • All car companies in the world are working on the electric drive, because governments are demanding it, not because customers are clamoring for it.

The show also responded to the concerns of many different callers on the expected topics: 

  • Price point and rebates
  • Charging and range questions
  • Safety of lithium ion batteries (they're safe). The batteries lose capacity gradually with age, after 5 years 80% capacity, after 10 years 70% capacity;...

Posted by Mark Nystrom, Oregon Fellow working for the Association of Oregon Counties

Over the past few weeks I have been gathering information about how communities outside the I-5 corridor feel about the electrification of transportation.  This task has led me on trips with Sarah to Coos County, Tillamook County and most recently Harney County. 

When I was first given this task I was uncertain how rural Oregon would respond to the idea of electrification.  After all, everyone knows that people away from the I-5 live on ranches and drive hundreds of miles a day.  Or that seems to be the prevailing thought.  According to an ODOT study, rural Oregonians actually spend about the same amount of time in their cars as their counterparts in Portland.  In fact, most people live in towns and make the same standard trips in their cars as people in Eugene, Salem or Portland: they drive their kids to school and practice, they go to work, they go grocery shopping.  In other words, the majority of people living outside the I-5 corridor could replace their gas fueled car with a PEV.  Even the residents of these communities seemed surprised at how little they actually use their car.

That’s what has made these trips so interesting.  Once people starting thinking about it, they get pretty excited.  The people on the coast are excited about the prospect of attracting tourists from the I-5 communities to their towns by setting up charging stations.  They recognize...

I've been thinking a lot about electric vehicles and have spent most of the summer talking to people about cars.  Over drinks at the brew-pup, at dinner parties, and cold calling folks in car related industries--- I've noodled a lot of opinions and perspective out of friends and strangers.  One thing that has come up consistently in these conversations is the cost of electric vehicles, followed by all the range and charging questions.  The cost issue is a nagging one in the back of my mind.  Yes, the cars cost money.  Yes, the cars cost quite a bit of money.  But wouldn't the sticker price be eventually smoothed out over the life of the vehicle? After all, you wouldn't be paying for much gasoline with most of the new EVs coming out, and in the case of the Leaf, you would only pay for electricity.  I've wondered about this all summer, so I finally started hunting through all my resources and I found a few car cost calculators online.  There are several out there.  Each make a different set of assumptions and none are perfect, but they do look at the life cycle costs of vehicle ownership, an essential thing to consider when making a decision about any type of car.   

The best one is the Project Get Ready Calculator by the Rocky Mountain Institute.  It allows you to select your state and inputs your current energy and gas prices.  It also allows you to choose from around 50...

OTREC participated in a research and technology funding discussion led by Mike Quear, congressional staffer. The visit consisted of two parts: a discussion with the Deans and faculty representing the major sciences at Portland State University; and a tour of the OTREC including highlighting collaborative research undertaken by the ITS Lab and electric vehicle initiatives being supported by OTREC. Mike Quear is Staff Director for the Science and Technology Committee’s Subcommittee on Technology and Innovation. He has worked for the Committee for the past 19 years. We always look forward to the thought provoking discussions that his visits provide.

PSU and OSU helped showcase the promise of electric vehicles in Oregon on Wednesday, April 8th by hosting Nissanís EV-02 model on each campus. Nissan announced that it plans to launch the fully electric vehicle in Oregon in 2010. At PSUís Urban Center, Angus Duncan (Chair of the Oregon Global Warming Commission), Joe Barra (Director of Customer Energy Resources for PGE), John MacArthur (Sustainable Transportation Program Manager for OTREC), and Tracy Woodard (Director of Government Affairs for Nissan-USA) briefed an audience of students, staff and faculty on the emergence of electric vehicles of Oregon. On OSUís campus, University President Ed Ray ìkicked the tiresî and engineering students exhibited their own car design and construction projects, including the SAE Formula and Baja Teams and the Solar Vehicle team. Also, OSU faculty had an opportunity to brief Nissan representatives regarding their education and research programs that prepare talent and spin out technology for this new industry.

Abstract: A variety of types of electric bicycles are now available to consumers in America and around the world. While there has been strong uptake of these vehicles in China, there remains uncertainty in other markets about their ultimate potential as a transportation mode. The technology is evolving in ways that are likely to better meet traveller's needs and the growth of this mode presents both opportunities and challenges. Since they have implications for transportation policy, planning and operations it is appropriate for the transportation profession to consider these vehicles carefully. This seminar will review developments and emerging issues with this form of transportation technology.

Abstract: This seminar will describe the results of a recent study for the Australian National Road Authority (Austroads) which reviewed emerging types of private vehicles, including everything from Segways and mobility scooters to three wheel cars and micro/mini cars, and their implications for road system management.The emergence of some of those vehicle types presents real challenges from the perspective of safely managing their integration into the road system even though they present some real opportunities from the perspective of improving the sustainability of the transport system. Although the analysis is largely from an Australian perspective, some of the general insights which came from the study are transferable and one of the key recommendations (regarding moving towards more performance based than prescriptive based standards for vehicles) has potential international application.

Over the last couple years, electric bicycles (e-bikes) have been gaining momentum. E-bikes may play an important role in addressing cities’ transportation and public health problems by getting more people out of cars and onto bicycles. But as the number of users increase, so too will potential conflicts (actual or perceived) with other road users, causing policy questions to arise.

The current state of e-bikes regulation varies dramatically across state and local jurisdictions, causing confusion. The confusion stems from the wide variety of devices and technologies on the market, perceived overlap of legal entities’ jurisdiction over the device, outdated or absent laws and regulations, and inconsistency of terms used to describe e-bikes. This confusion creates uncertainty for manufacturers and dealers and makes riders wary of embracing e-bikes.

One of the biggest concerns people have about e-bikes and their use, especially on shared-use paths, is speed....

Summary: Electric bicycles (e-bikes) are well established in China and other Asian and European countries but have yet to realize their potential in the United States, although recently the number of e-bikes has been growing. Research on the economic, operational, and safety issues of e-bikes in the U.S. is limited. This research aims in part to understand if different bicycling technology, in this case electric assist bicycles or e-bikes, can reduce barriers to bicycling and encourage more bike trips and longer bike trips, and increase the diversity of people bicycling, including people with a disability or chronic injury to bicycle. Some of these barriers include trip distance, topography, time, and rider effort. E-bikes typically resemble a standard pedal bicycle with the addition of a rechargeable battery and electric motor to assist the rider with propulsion. To answer these questions, we conducted an online survey of existing e-bike users on their purchase and use decisions. Results from 553 e-bike users across North America are analyzed here. Results suggest that e-bikes are enabling users to bike more often, to more distant locations, and to carry more cargo with them. Additionally, e-bikes allow people who would otherwise not be able...
