Battery Range

In the last few days I have been thinking about the kind of battery range I will need given the fact that I will not be able to Plug-In at work in the near future. Once again, I am gravitating towards the Thundersky lithium batteries and I am reading about many other EV owners taking this route. I calculated that 40 TS-LFP160AHA batteries would work out nicely. I would be able to either place the entire 40 pack in the trunk or break up the pack into two and place 30 in the rear and 10 in the front. The overall weight of the car would remain low (same or less than the original weight). According to certain vendor specs, 40 of these batteries could give me an approximate range of 100 km at a cruising speed of 60 mph which would be great and I would only need to charge once at home overnight.

Here is a sketch of a 40 pack of TS-LFP160AHA:

Last night I was watching CBC Television's "The Nature Of Things" program. The episode named "The Suzuki Diaries" about sustainability showed how different countries are harnessing nature's free energy while creating healthy economies and cleaner environments. If you have a chance to watch this, it is very interesting.

This goes ANY distance, bu needs the car companies to put it in motion.

In the 1960s the U.S. Congress created the Department of Transportation (DOT), with authority to control many aspects of the transportation. One of the new Department's first acts was to develop legislation supporting urban transport. But basic problems remained, and indeed grew faster than the population, and faster than the gross national product. More families became multi-car families, driving more trips each, and less alternative transports were available to greater portions of our population.
President Clinton, to improve urban travel, agreed in 1991 to support $-billions for yet another program of development. His introduction of funding of magnetically-propelled transport systems came at a time when it had become apparent that further development of the road-only traffic systems would lead to catastrophic climatic damages, as well as increasing world land use, with its accompanying social disruption.
The test center in Pueblo, Colorado set out to develop a vehicular system that made use of magnetism. The system made use of magnetically elevated vehicles. But they were then propelled by mighty aircraft-like IC. engines! Other work produced wheel-less vehicles that maintained a separation from the road with an air cushion. All these developments were taken into use, providing mass-transits that left the internal engine supreme for the car.
The pollution problem continued unabated.
By the start of the 21st century, another problem of global proportions was gaining public attention, caused by the emanation of sundry pollutants into the atmosphere and commonly named Global warming.
As the third world develops, and scramble to join the automobile rat-race, the damage done universally to the Earth has dramatically increased. Probably the major source of the damage today is atmospheric reflection, Global warming, or more accurately, Global Climate Change.
Making some use of the upper limits has become (relatively) simple with photovoltaic generation of electrical power. And because the Linear motor – the work-horse of the Amcar
system – drives vehicles using direct current electrical power, this system is intrinsically
more efficient than AC uses of the power generated from solar sources (about 30% more efficient). Global leaders called for a variety of half-measures including the ‘carbon tax,’ but
The pollution problem continued, unabated.
Not only do present cars release greenhouse gases, but the dust from tires, typically hydrocarbon and silica pollutants, remain in the lower atmosphere for indefinite periods.
Other health-related problems, of carcinogens and agricultural losses are also improved by Amcars. This system eliminates them as it is a wheel-less vehicle, taking the Linear Motor from its common use on the factory floor. Amcars offer a different practical use for it, as the ‘Guideway.’ A second patent from the 1920s, the ‘Merger,’ allows the wheel-less vehicles to glide smoothly from their course on one Guideway to another, use electromagnetism to speed their vehicle on. It offers riders the ability to choose their path and destination.
Finally, with developments in major solar power, of up to 6kWh/square meter/hour, from Photovoltaics of the end of the 20th Century, the whole system can be powered by renewable energy. Amcars requires no roads, very little carbon fuels and works best when the vehicles are not quickly obsolescent. Read ‘The Power Play to End the Car.’[ISBN 978-1-60693-139-4]
