Speakers included Jeff Shepard, president of Darnell, Jerry ruddle, executive vice president with Advanced Cerametrics and Solicore’s vice president, Jarreth Solomon.

Next time you’re behind the wheel, don’t be surprised if the 100% electric Tesla Roadster pulls up next to you. According to Tesla Motors president and CEO Ze’ev Drori, 12 production Roadsters have arrived in California, and 27 more are in various stages of assembly. Drori also expects four more to arrive each week through August.

Analog and power guru Bob Pease corresponds with readers about the latest proposals for electric cars in this exclusive online edition of his popular mailbag.

By 2010, a booming demand for solar energy will increase worldwide investments in the production of Photovoltaic (PV) cells to the same level as those for semiconductor manufacturing, according to iSuppli. The market research group predicts global production of PV cells will rise to as much as 12 GW by 2010, up from 3.5 GW in 2007.

Calling it a milestone towards fabricating low-cost GaN power devices for high-efficiency/high-power systems beyond the limits of silicon, IMEC and Aixtron have grown high-quality, uniform AlGaN/GaN heterostructures on 200-mm wafers. This is the first time crack-free AlGaN/GaN structures have been deposited onto 200-mm Si(111) wafers, according to the companies.

The IEEE has named István Nagy recipient of the organization’s 2008 William Newell Award for his work in developing four generations of excitation systems for large electric power plants. Nagy is a research professor at the Budapest University of Technology in Hungary.

A new standard from the Telecommunications Industry Association defines a data modem that operates on electrical wiring (ac power lines) on users’ premises. The document, TIA-1113, “Medium-Speed (up to 14-Mbit/s) Power Line Communications (PLC) Modems Using Windowed OFDM,” is the first global multi-megabit, broadcast class, PLC standard approved by ANSI, according to the association.

Texas Instruments Inc. has become a full member and participating company in the recently established EnOcean Alliance. The Alliance was founded last month to establish a global standard for sustainable buildings based upon EnOcean’s revolutionary energy-harvesting wireless technology.

Anadigics has begun volume shipments of its AWT6277 WCDMA power amplifier modules to LG Electronics for use in the new LG Viewty (LG-KU990), a 5.0-Mpixel professional-level camera phone currently available in the UK. Specifically designed to meet the needs of feature-rich mobile handsets, the AWT6277 includes Anadigics’ HELP technology, which reduces WCDMA average power consumption by 50%.

The second meeting of the Alliance for Universal Power Supplies (AUPS) will focus on questions such as how power is really distributed in the office, how China established a workable cell-phone-charging standard, and how the Environmental Protection Agency views the proliferation of power supplies. The half-day meeting is scheduled for June 13 at the PG&E Auditorium in San Francisco

The Universal Powerline Association has scheduled the UPA Powerline Interop 2008 Certification, the first global interoperability and certification program event for BPL Access and In-Building Powerline networking. The program will launch with a two-day Official UPA Plugtest and Certification event June 25-26.

MIT engineers have boosted the power output of direct methanol fuel cells (DMFCs) using a new material that offers several advantages, including lower cost than its traditional counterpart. DMFCs also have potential applications in other electrochemical systems, such as batteries.

Looking to further strengthen its activities in the field of power management applications, Infineon Technologies has acquired Primarion Inc. The Torrance, Calif.-based Primarion is a fabless company that designs, manufactures, and markets digital power ICs for Computing, graphics, and communication applications.

Speed and accuracy don’t always go hand-in-hand in DC/DC converter systems—that is, until now. The LTC3811 is a dual output, fi xed frequency current mode DC/DC switching regulator controller designed for one of today’s most demanding power supply applications: high current, low voltage processor core supplies.

After more than 60 years at the helm of the company he founded in 1947, Eric Lidow will retire as chairman and member of the board of directors of International Rectifier Corp. effective May 1. Lidow transformed the start-up company, which developed selenium photoelectric cells and selenium rectifiers, into a leader in power management technology.

Maxim Integrated Products and Intel Corp. are collaborating on highly integrated power-management and multimedia solutions for Intel-based Mobile Internet Devices (MIDs). Maxim will provide mixed-signal ICs that enable longer battery life and a rich multimedia experience for consumers.

Electric and hybrid luxury cars like Tesla’s Roadster and Fisker Automotive’s Karma may grab the headlines—and celebrity owners. But what if you’re an early adopter on a budget? Maybe you should take a look at Aptera’s latest models. Scheduled for production later this year, the all-electric Typ-1e will cost approximately $26,900, while the plug-in series hybrid Typ-1h will go for about $29,900.

The market for transparent conductors used in display, photovoltaic, and lighting markets will reach approximately $9.4 billion by 2015, according to a new study from NanoMarkets, an industry analysis firm.
