GM's Volt Save the Company? Need The Truth?

Behind Obama and criticism from the head of the council months ago, GM built the necessary steps to ensure that plug-in hybrid Chevrolet Volt is, commercial success.

Last week, GM, Mr Obama said he does not need to convince, and plans to increase the rejection, and the automaker warned that in May before the bankruptcy. Part of the problem, according to the administration reports that the company is not the right mix to compete with manufacturers of motor vehicles. For example, V, Toyota has been the leader in green technology vehicles "that are expected to be much more expensive than gasoline, fuel and colleagues may have to reduce the production of a dynamic business," said the report.

But the Volt in GM's plan for "reinventing our company," said Tony Posawatz, vehicle line manager for the Volt, in a conference call with reporters last week. Cars will be used again in May and the 40 miles without gasoline. During the trip, ship generators, gasoline or ethanol, the battery is in the range cars. GM plans to use the basic platform for the Volt in a variety of vehicles. This gave two products in the car, Cadillac and other plug-in hybrids for Europe.

Car With 50 Miles Of Battery-Powered Range.

The first module in the hybrid, which is sold in the United States, may, Fisker Karma, as the release in November. Fisker Automotive, which introduced the concept of karma, in January, recently at $ 87 million, which should be in manufacture. A number of other plug-in hybrids, including models from GM, Chrysler and Toyota planned on coming years.

Reputation is a luxury car of four people can use, and again on battery power only for 50 miles. Then, running on generator fuel onboard battery contents back, extending 250 miles from the content box. In the production of electricity from solar panels on the roof of choice, especially for parking, but some of them may also be the battery. Car battery lithium manganese oxide, lithium Advanced Energy, based in Vancouver, British Columbia. Battery with the same options for Chevrolet Volt, a plug-in hybrid, due in November 2010.

Henrik Fisker, the designer free, and co-founder, said that the New York Auto Show last month that the car is part of the effort to prove that in a small car, rather than opinion. To return to action, a car, the high price of $ 87,000.

This machine is faster, but not green as a plug-in for another big size. Two 150-kilowatt electric motor of 403 hp - enough for 60 miles per hour in 5.8 seconds. (It took more than 9 seconds, volts.) However, the nature of the acceleration in the "Sport", the second battery power and natural gas generators. Stealth mode requires a driver exclusively on electricity stored in batteries.

Brand New Liquid Battery

Without a good opportunity for the storage of electricity on a large scale, solar energy is not right on the night. One of the most promising option is the storage, a new type of battery with a liquid. Prototypes of the liquid will take less than a third of the battery and this reaction may be more.

Battery that is not like other. Metal electrodes, electrolytes, and the time between them and salt. This leads to the remarkable stability of the aircraft can quickly absorb much energy. Electrodes, electric "tens of times [battery], which is measured," said Donald Sadoway, chemistry, MIT professor and one of the inventors of the battery. In addition, the materials cheap, and can easily industries.

The first prototype consists of a plateau surrounded by insulating material. Researchers have been melt, add the raw material: the antimony sulfide electrolytes such as sodium in the middle, and magnesium in the head. Because each material has a different density, they also differ in the natural situation, the simplification of industry. Container for a collector, the power of electrons, such as solar panels or electricity to the network for business and residential customers.

"Kitching" Atomic Magnetometers

Magnetic fields are everywhere, from the human body with a metal buried in the mine. Even molecules such as proteins to produce their own magnetic fields. Both magnetic resonance imaging (MRI), a description of the body, and NMR spectroscopy (NMR) studies of protein and other substances, such as oil, depending on the magnetic information. But this current sensor to detect the weak, but significant magnetic fields are weak. Some portable and inexpensive, but not very sensitive, very sensitive, but also other stationary, expensive and power.

Kitching Now John, a physicist at the National Institute of Standards and Technology in Boulder, CO, is the development of small, low-power magnetic sensors almost as sensitive as the big, expensive land. About the size of a thick grain rice, called the atomic magnetometer sensors. Kitching hope that one day in the portable MRI machine is faster and cheaper detectors for blind pedestrians.

Small sensor that consists of three parts, vertically in the silicon chip. Ready for infrared laser and infrared photo-detector silicon sandwich and a glass cube with the evaporated cesium atoms. In the absence of a magnetic field, the laser light by cesium atom. Even before the very weak magnetic fields when the atom to change, so that they absorb light in proportion to the strength of the field. This amendment is supported by photo cells. "This is a simple configuration with highly good sensitivity," Kitching says.
