You are right that solar source of energy is available, but not at night time hours. It's only derived only from light and heat of the sun, it's necessary to have sunlight and you have to have the proper storage system in order to utilize solar energy resources after sundown.
I understand your point, but have you heard about the Stanford University Solar Car in October 2011 World Solar Challenge in Australia. The car electrical system only depends on solar source with no battery, that's the area I'm looking at.
Until now, I hadn't seen the costs for EVs broken down to dollars and cents. That is a fantastic data point and a good argument in favor of EVs. They are still a little pricey upfront, as you mentioned, but look like a great long-term investment. Thanks for the analysis!
@Anne, The fact that a car is a solar recharged does not make it independent of using battery. It just means that the battery that stores the energy used by the car is being charges by solar energy. The battery thing is still an essential part of the car. But instead of having to park for some time to charge , you cann do that while still driving because the source or means of charging is just above you- the sun
That was a good point which may not seem to be a problem now because the manufacturers will promise making spare battery available but how often do i have to change this battery in a year or within six months because the best of battery is still battery.
This idea of a Battery Station is worth exploring from the commercial angle as it can boost the viability of using EVs on highways .
In fact I had once worked out the economics behind setting up such a charging station and it can be a profitable business. BY having a centralised battery charging staion , it will be more economical to charge the batteries by a centralised charging system than doing it at every home by the individual by using the personal chargers.
It will be convenient, cost effective and if the batter replacement happens in a matter of minutes who will care for using the gasolene cars?
With intelliigent battery monitoring system installed in every battery pack , it will be possible to keep track of remaining battery life, no of charge cycles applied, and all that information.
This concept is worth exploring and the future EVs should be designed with this concept in mind.
But wouldn't that require a lot of space to store a large number of big sized batteries? It might save some space and effort if the technology produces robots that can charge up a battery within minutes instead..
