Scientists have devised a way to use heartbeat and blood flow to generate electricity to charge military equipment, and maybe even your cell phone one day.

Low-frequency vibrations from any source of movement, including a heartbeat, blood flow and even the wind against your clothes, creates mechanical stress, which in turn produces electricity through the cyclical stretching and releasing of specially designed nano thin, zinc oxide wires, according to researchers at Georgia Institute of Technology.

The new nano-scale "flexible charge pump" generator produces alternating current. The greater the strain rate, the more electricity generated.

"Quite simply, this … Read more

Electric vehicles equipped with fast-charging capability are headed to production and will be on the road next year.

All that's needed to reduce the charging time for these cars from hours to minutes are Level 3 440-volt fast-charging stations. But to date, none are public.

Ecotality, a clean-technology company in Scottsdale, Ariz., wants to fill that void. It designs and sells these rapid rechargers for $15,000 to $35,000, depending on the structure requirements, mostly to warehouses and airports for fleet vehicles.

Given Ecotality's partnership with Nissan, the Tucson Metro Area, and the Pima Association of Governments (… Read more

Nissan announced a partnership with San Diego Gas and Electric to develop and promote an electric vehicle-charging network for the San Diego area.

The automaker will help the power company acquire electric vehicles and will work with agencies and city departments to flesh out EV infrastructure implementation to make San Diego "plug-in ready."

SDG&E has made a commitment to bring 100 of Nissan's EV to San Diego to start, and Nissan representative Katherine Zachary said she expects zeros to be added to that number in the future.

For consumers, Nissan will publish deployment plans for … Read more

Last week I wrote about Taxi Magic (download), an iPhone app that, along with RideCharge--its cousin for BlackBerry and Windows Mobile phones--lets you order a cab to your present location, and track it as it wends its way toward you. Version 1.1, released on Wednesday, gives Taxi Magic the one main feature missing from its BlackBerry and Windows Mobile counterparts: the ability to pay your cab fare with a tap of the iPhone.

This mobile payment option works by associating one or more credit cards to your RideCharge account (RideCharge's privacy policy). When it's time to pay, … Read more

Not everyone is as lucky as we are to work adjacent to a hotel with a fresh supply of taxicabs pulling up to its curb. When you're stuck without a ride, cab-calling applications can make ordering a taxi through local companies a surer, safer thing than throwing yourself in the middle of a darkened street and flailing your arms wildly.

A recent application we've looked at, RideCharge for BlackBerry and Windows Mobile (www.ridecharge.com from the mobile browser), not only lets you order a cab from your phone without placing a call, but it also has you … Read more

Telsa Motor's Model S sedan--set to debut March 26--will have 440-volt fast-charging battery capability, wrote Rachel Konrad, spokesperson for Tesla Motors, to CNET in an e-mail.

Although Konrad could not say how long it would take to charge the Model S sedan using either a 440-volt charger or the standard 220-volt charger, the Tesla Roadster's battery can be fully charged in about 3.5 hours using a 220V/70A system, she wrote.

The Model S is expected to have a driving range of 225 miles on a full charge. It's not a fair comparison, but Nissan's … Read more

Nissan recently announced a partnership with the city governments of the Tucson Metro Area and the Pima Association of Governments (PAG), a nonprofit metropolitan planning organization in the Tucson area, to help them prepare for the anticipated wave of electric cars.

Most of the market research to plan and implement an EV-charging network will be done by ECOtality, a clean-electric transportation and technology company in Scottsdale, Arizona.

Part of Nissan's role will be to help PAG acquire electric vehicles. Nissan has been promising to come out with an all-electric car in late 2010, although it won't say what it is. Nissan has been adamant that the electric vehicle will not be the prototype electric Cube that was displayed in car shows last year, but it has committed that the car will be able to get up to 100 miles on a single charge. The five-passenger compact car will be about the size of a Sentra.

The new electric car will be equipped to handle the next-generation of 440-volt fast-charging stations, says Nissan spokesperson Katherine Zachary. The fast-charging stations are able to charge Nissan's electric car in 26 minutes and will be critical to extending transportation corridors and easing consumer fears of being stranded for hours with a drained battery. … Read more

Alternative energy company Ecotality said on Friday that it will supply charging stations in Arizona as part of the planned roll-out of plug-in electric cars from Nissan next year.

Nissan North America has committed to making its electric vehicles available to municipal or private organizations in the Tucson, Ariz., area, Ecotality said. Nissan's all-electric sedan is scheduled to be available in certain areas of the U.S. next year.

Ecotality said it will plan the installation of charging stations in the area and work with local politicians to establish policies to promote plug-in electric cars.

There are a number … Read more

With the roll-out of plug-in and electric vehicles this year, car owners are going to need to know where else besides their home they can charge their car. Communities are working to accommodate these new vehicles by installing public charging facilities, but that won't help much if no one can find them.

Tying the pieces together is the Electric Vehicle Charging Stations Map created and maintained by the Cleantech Authority, an environment-conscious information hub that provides actionable resources for readers to use. … Read more
