Faced with ongoing problems in developing a transmission that will deliver on the electric Roadster’s initial specification for acceleration (0-60 in 4 seconds), Tesla Motors will begin production in 2008 with an interim transmission design, according to CEO Ze’ev Drori.
Review Panel Recommends “No-Go” on Further Funding for Sodium Borohydride for On-Board Vehicular Hydrogen Storage
An independent technical review panel convened at the behest of the Department of Energy to consider the technical status and progress of R&D on the hydrolysis of sodium borohydride (NaBH4) for on-board vehicular hydrogen storage has unanimously recommended a “no-go” to further funding.
Millenium Cell and others have been working on sodium borohydride-based systems for a range of applications, from portable devices to transportation. DaimlerChrysler used Millenium Cell technology it its Natrium fuel cell concept car, introduced in 2001. The Natrium (Latin for sodium, and the origin of the “Na” symbol for the element) was based on a Town and Country minivan, and used a Millenium Cell fuel processor with a Ballard fuel cell, Siemens motor and SAFT Li-ion battery pack.

The Kansas Department of Agriculture is launching a one-year pilot project that will allow flexible-fuel vehicle owners to purchase a range of ethanol blends such as E20, E30, E50 or E85. Currently there are 28 stations in Kansas selling E85 fuel.
To ensure that owners of conventional vehicles don’t accidentally pump a higher ethanol blend into their vehicle, the pumps will feature a bright orange label with the message “For use in flexible fuel vehicles only.”
German researchers have developed a new class of inorganic ionic conductor featuring high lithium ion mobility. In ionic conductors, charge is not transported in the form of electrons as it is in metals; instead, the charge is transported in the form of charged particles—typically, lithium ions. This transport requires materials in which the lithium ions can move as freely as possible.
The team, led by Hans-Jörg Deiseroth from the University of Siegen, in cooperation with scientists at the University of Münster, developed a set of argyrodite minerals made of lithium, phosphorus, sulfur, and bromine atoms. They report the characterization of the most conductive representative of the engineered argyrodite minerals in the journal Angewandte Chemie.
Mahindra & Mahindra recently introduced its new Scorpio V-Series SUVs, equipped with the new “mHawk” 2.2-liter turbodiesel. The company will continue to offer the older CRDe 2.6-liter diesel models in the Scorpio line-up.
Honda Motor Co. may be able to start mass-producing fuel cell vehicles within 10 years, President Takeo Fukui said in an interview with Jiji Press. Fukui emphasized Honda’s intention to focus on fuel cell vehicles, rather than electric vehicles.
The US Environmental Protection Agency (EPA) has published a report assessing the various waste discharges from cruise ships, and is seeking public input on the report, as well as input regarding options, alternatives, and recommendations about whether and how to better control and regulate the waste streams described.
