Get Ready for Electric Cars

Ho, hum, Gas is still relatively cheap, but the population is growing that constantly shortens the finite supply of petroleum.On the contrary, electricity is expensive and the grid is already overloaded. Therefore why electric cars. The big problems are that supply is finite and also adds to the contamination of our atmosphere.
So, why not electric cars? Well there are still problems that require resolution. First, we are used to driving in to a gas station and saying fill er up.In less than fifteen minutes we are again on our way. Gas stations are located at almost every major intersection and therefore easy to stop and fill up.
If the country switches to electric cars, except in California, the stations available are not easily found. Therefore one frets a little bit longer when the gauge is reading close to empty. However, we well know as the need increases, there will be more and more stations available.
All well and good, not a big problem. However, consider that fifteen minutes to fill up and get underway. With the electric car, under current conditions, to achieve an additional distance of say, 300 miles, the electric car requires an hour to recharge. Ouch, that is not what the public wants.
The other factor the public expects is performance. That means that a battery needs to supply the proper energy to start the car, get it up to speed in a short period of time and maintain driving conditions until it is time to cease operation.
These conditions are obtained by a battery that supplies a motor with a proper supply of volts required to provide power to accomplish supply a transmission system to do the job. Currently the battery is the point of concern. Concerns include sealants, thermal insulation,conductivity , noise, vibration, shock, flame retardation barriers, tape resistant to hot, cold and cyclic temperature.These sound like insurmountable problems; and only time will tell whether sufficient advancements can be made.
However, the battery drives a motor which in turn controls transmission to the axles. These too affect the ability of the battery to perform and maintain sufficient life for efficient operation.Weight loss or more efficient performance by these components support the battery performance. MagnaTech is directing its energy to development of rotor component of the P/M motor that transmits energy to the transmission. If more power becomes available through added power supply to the transmission, then the battery can become more efficient, providing improved mileage before requiring a recharge. In addition, if the resistivity of the rotor segments can be improved, the car performance also is improved. If  the resistivity can be increased, power is also further increased and also temperature reduction is possible .MagnaTech is working on a new alloy that we expect will improve the properties stated above and thereby extend both life and performance of batteries. Furthermore, if successful, the development could result in decrease in motor weight, also improving battery performance. MagnaTech is seeking funding and partnership for commercialization of this improvement in performance of these P/M motors.
