Tesla breaks record for going the distance

•A record for a Tesla Roadster driven on a single charge was set at 313 miles (501 km) in Australia on Tuesday.
•Tesla Roadster owner Simon Hackett and his friend Emilis Prelgauskas drove his electric sports car from Alice Springs, Northern Territory, to Coober Pedy, South Australia, as part of an alternative-fuel vehicle rally called the Global Green Challenge.
•The Tesla's electric-charge port door was sealed shut at the start of the 313-mile journey and the trip was filmed for a documentary, as well as monitored by contest officials. The Tesla's lithium ion battery, which the company assures owners will last over 200 miles between charges under normal driving circumstances, had 3 miles to spare when the team reached its destination in Coober Pedy, according to Hackett's chronicles of the race experience on his company blog. (Hackett happens to also be the founder and managing director of Internode, an Australian national broadband and Internet services company.)
•Hackett said in his blog the achievement is actually a record for any production electric car, not just a Tesla Roadster, which is why his team was so careful to record it. To squeeze as much distance out of the Tesla's battery as they could, Hackett and Prelgauskas tried to drive at a consistent speed of 55 kph (roughly 34 mph) for a large portion of the almost 12-hour journey.
•"The security seal was applied to the charge port door when we started the journey. As this is being done as part of the Global Green Challenge, we have a full set of official verifiers here who will attest to the results and to achieving the outcome. We were followed along the journey by our support crew and a documentary film crew--so we have it on film," said Hackett.
•While Tesla Motors is not an official sponsor of the contest or Hackett, the company has shown support by spreading the news of Hackett's success. It's not hard to imagine why as Tesla poises for a major retail expansion.
•The stunt may certainly speak to consumers who likely drive nowhere near 313 miles in a single day, but are still reluctant to hem themselves in with a car restricted to a limited number of miles between recharges.

Tesla raises $82.5 million for new retail stores

Tesla Motors has garnered $82.5 million in "Series F" funding for the purpose of expanding its chain of stores in North America and Europe.
The deal was first announced Monday by participating investor Fjord Capital Partners. Tesla Motors then confirmed the deal to several news outlets on Tuesday. Daimler, already a 10 percent investor in Tesla, and Abu Dhabi fund Aabar Investments also contributed to the fund.
The California-based electric-vehicle manufacturer has had stores in Los Angeles and Menlo Park, Calif., for some time. It recently opened stores in New York, Chicago, Miami, London, Seattle, and Munich. It has plans to open a store in Monaco before the end of the year, and has said it's scouting for locations in Washington, D.C., and Toronto.
But don't call them dealerships.
Because the electric cars are light on service work, and don't need things like oil changes, Tesla plans to forgo the traditional dealership/service business model of yesteryear's car industry. Instead the company plans to maintain full retail control over its cars and brand, Tesla announced in early September.
"Tesla takes its showroom cues from Apple, Starbucks and other customer-focused retailers. Tesla stores provide a welcoming spot to surf the Web, test drive cars and learn more about Tesla, the only production automaker selling highway-capable EVs in North America or Europe," Tesla said in statement.
News of the latest funding deal also follows the unveiling of Tesla's production model of the Model S sedan, as well as a tuner version of its Roadster, at the 2009 Frankfurt auto show this week.
The prototype of the Model S was unveiled in March as a way to augment Tesla's lineup with a more "economical" option to its Roadster luxury sports car. The Model S is expected to cost around $50,000--about half the cost of the Roadster.

Smart meters coming to a utility near you

After 100 years, the lowly utility meter is poised for a digital upgrade, with the installation of up to 250 million expected over the next six years, according to a new forecast.
Pike Research published on Monday a research report on smart meters that predicts installation to ramp up at a 19 percent annual rate through 2015.
Smart meters use wireless networking to shuttle information back and forth between utilities and customers. So far, the communications link has been used mainly to report back usage for monthly billing, but there are new applications aimed at efficiency.
Consumers can, in some cases, get a real-time read-out of electricity consumption or see a graph of a full day's use. Smart meters are also designed to help consumers take advantage of off-peak rates. Utilities are generally interested in moving usage to off-peak times and running power plants more efficiently.
A person could, for example, schedule a dishwasher to run or charge a plug-in vehicle in the middle of the night. Information from the smart meter signals when cheaper rates are in effect.
Pike's forecast notes that the push to smart meters is global, driven by government interest in energy efficiency. The U.S. Department of Energy's smart-grid grant program announced last week is expected to result in 18 million smart meter installations across the nation. About 3.5 percent of the world's meters can be considered "smart," with the number set to grow to 18 percent by 2015.
Despite the spike in installations, there are a number of technical barriers to overcome, including a lack of standards. In particular, there is a "jumble" of different neighborhood-area networking technologies to carry data from homes back to utilities. The most advanced smart meters have the ability to connect to home-area networks.

Zinc air battery maker looks beyond lithium

Start-up ReVolt Technology is developing rechargeable zinc air batteries, a technology it says promises longer runtime for consumer electronics and plug-in vehicles.

The Switzerland-based company, which was spun out of a Norwegian research institute five years ago, anticipates commercializing a rechargeable coin-size batteries next year. But the technology has the potential to be a cheaper and more energy-dense alternative to lithium ion batteries in consumer electronics, grid storage, and transportation, according to CEO James McDougall.
Zinc air batteries, which are already used in hearing aids, create an electrical current through a chemical reaction between zinc and the oxygen in air. Researchers have pursued rechargeable zinc air batteries for many years because zinc is relatively abundant and the internal chemistry, safe.
But there remain some technical challenges. After multiple charge-discharge cycle, the anode in zinc air batteries can become damaged and stop working. McDougall said ReVolt is trying to reach between 500 and 2,000 charge cycles, depending on whether the battery is used for consumer electronics or large-scale storage.
ReVolt engineers are working on a new design in which a zinc slurry is pumped through tubes that act as an air electrode, causing the chemical reaction that produces a current, McDougall explained. He expects it will take four or five years to commercialize the technology for large-scale applications, such as grid storage. The company has raised 24 million Euros in funding, including an investment from power generator RWE of Germany, which is looking at the zinc air for storage on the electricity grid. ReVolt has applied for an ARPA-E grant aimed at breakthrough energy technologies but was not chosen in the first round of awards.
For vehicles, it makes sense to combine the relatively large energy storage of zinc air batteries with other storage technologies, McDougall said. Power-dense lithium ion batteries could be used for boosts of acceleration and ultracapacitors could capture energy from regenerative braking. "You could increase the range of next-generation of electric vehicles with hybrid storage... You could get three times the range, eliminate the safety concerns, and cut the cost of the system," he said.

Empire State Building strikes back...against pollution

What was once the world's tallest skyscraper now aims to be the greenest.

(Credit: Rocky Mountain Institute)New York's iconic Empire State Building, which played a starring role in the movie "King Kong," is set to undergo a retrofit that could cut the 102-story building's energy consumption by up to 38 percent. The energy-saving measures will initially cost approximately $20 million and will take an estimated two years to implement, according to press materials.

The program includes upgrades of the 1931 Art Deco building's 6,500 windows, radiator insulation, a new air-conditioning and heating system, air handler replacements, energy-efficient lighting, upgraded ventilation control, and an Internet-based system for tenants to monitor their energy use (that also teaches them how to conserve energy.)

"By pursuing these strategies, owners can save millions of dollars and enhance asset values while significantly reducing greenhouse gas emissions," said Raymond Quartararo, a director at Jones Lang LaSalle, a real estate consultancy that's helping manage the retrofit. "That's a win-win for owners, tenants and the global environment," he added, according to a press release.

Other organizations involved in the greening of the Empire State Building include the Rocky Mountain Institute and the Clinton Climate Initiative, which has been working with cities on projects to save energy and reducing carbon dioxide emissions in buildings.

In both the U.S. and EU, buildings--both commercial and residential--are the largest consumers of energy, accounting for 40 percent of the total energy consumption in both locations, according to sources including the Energy Information Administration. And in big cities, buildings are dominating the environmental footprint. For instance, buildings are responsible for 79 percent of all carbon emissions in New York City.

Project leaders hope the Empire State Building retrofit will result in an estimated annual energy savings of $4.4 million and could reduce carbon dioxide emissions by 105,000 metric tons over the next 15 years. That's equivalent to the annual emissions of 17,500 cars.

"If we can show that in a building like this that it makes money for the owner, and it makes money for the tenants, its pretty hard for anybody to ignore it," said James Russell, of the Clinton Climate Initiative, in anYouTube video. "It is a fantastic global flagship example for others to copy."

BART signs up for 20 years of Wi-Fi

BART, the San Francisco Bay Area's commuter railway, plans to offer Wi-Fi access on all trains and at all stations by 2011, the San Francisco Chronicle reported Saturday.

The 20-year deal, signed Friday with start-up Wi-Fi Rail, is set to bring high-speed wireless access to BART's 104 miles of track and 43 stations. The network is based on a "huge fiber-optic backbone," according to Wi-Fi Rail.

BART, short for Bay Area Rapid Transit, has been testing the service for about a year in underground sections in San Francisco and on about two miles of open track in Hayward. More than 16,000 people signed up for the pilot service, which has been free, the Chronicle said. Wi-Fi Rail plans to charge $30 per month once the service is fully installed. Other subscription plans, based on hourly, daily, or annual use, will also be available.

According to Wi-Fi Rail, tests on trains running at more than 81 mph "have consistently demonstrated upload and download speeds in excess of 15Mbps."

The company, founded in 2005, is based in the Sacramento area.

Clear Carbon-Nanotube Films

Special sheets for bendable displays and solar cells will soon hit the market.

The first electronic product using carbon nanotubes is slated to hit the market this year. Unidym, a startup based in Menlo Park, CA, plans to start selling rolls of its carbon-nanotube-coated plastic films in the second half of 2009.

The transparent, conductive films could make manufacturing LCD screens faster and cheaper. They could enhance the life of touch panels used in ATM screens and supermarket kiosks. They might also pave the way for flexible thin-film solar cells and bright, roll-up color displays. The displays could be used in cell phones, billboards, and electronic books and magazines.

In all of these applications, the nanotube sheets would replace the indium tin oxide (ITO) coatings that are currently used as transparent electrodes. ITO cracks easily and is a more expensive material. "The cost of indium has gone up by 100 times in the last 10 years," says Peter Harrop, chairman of IDTechEx, a research and consulting firm based in Cambridge, U.K.

Sean Olson, vice president of business development at Unidym, says that touch panels--which are particularly susceptible to the brittleness of ITO--will be the first market that the company will target. He says that Unidym is already working with leading touch-panel makers.

Many display manufacturers are working on products using the new films. In October, Samsung demonstrated the first prototype of a 14.3-inch color electronic paper device made with the films. Earlier last year, at the Society for Information Display symposium, Unidym demonstrated a color LCD prototype in collaboration with Silicon Display Technology, based in Seoul, Korea. Unidym is also working with Japanese chemical company Nippon Kayaku to make thin-film solar cells.

Using nanotube films instead of ITO coatings would bring multiple advantages to display manufacturers. Carbon is a cheap, abundant material. Carbon nanotubes are stronger and more flexible than ITO. Most important, the nanotube films are easier to deposit on plastic and glass substrates.

"The big benefit LCD guys are looking at is not materials cost," Olson says. "It's going from ITO, which [requires] vacuum deposition, to something that is more easily coated." That would increase the company's yields and bring down production costs.

The new film is a tangled mat of carbon nanotubes on plastic. Unidym's method to manufacture nanotubes is a key technology breakthrough. Electronic products with carbon nanotubes have been kept at bay mainly because of the difficulty in making pure batches of high-performance conducting nanotubes at reasonable cost. Batches of the material contain tubes that are both conducting and semiconducting. Nanotubes' properties also depend on other factors, such as length, diameter, and the number of walls that they have.

Unidym uses a chemical vapor deposition method to grow the material. A mixture of carbon-containing gas and a metal-catalyst-coated substrate is heated at a high temperature. The carbon atoms from the gas attach to the substrate and form nanotubes. Then the company uses purification processes, including oxidation and acid treatment, to remove unwanted nanotubes and contaminants, such as other forms of carbon.

Unidym has also patented a process to disperse the nanotubes in a liquid. It uses a roll-to-roll technique akin to printing on paper to deposit the nanotube ink on plastic. The company can print at speeds up to 50 meters a minute. Olson won't divulge any more information but says that the company has "optimized these techniques to get the best transparent, conductive film performance."

At least one other ITO replacement is already being sold. Fujitsu is using a transparent, conducting organic polymer to make touch screens. However, the polymer degrades over time when exposed to heat or light, and its conductivity is not high enough for use in LCDs or electronic-paper displays.

Other potential ITO replacements are currently being worked on in various labs. Many research groups are making advances with the carbon material graphene. University of Michigan electrical-engineering and computer-science professor L. Jay Guo has made grids of extremely thin metal wires. He says that these would be more suitable than carbon nanotubes for making electrodes on thin-film solar cells because they would enhance light absorption. "Think of it as concentrating incoming sunlight energy into a very thin layer," Guo says.

But Unidym's carbon-nanotube films could be the first viable ITO replacement for touch screens, flexible displays, and thin-film solar cells. Unidym is also developing printable thin-film transistors and fuel-cell electrodes using carbon nanotubes.
