So I just got this iPhone app that shows a bunch of charging stations & I notice they charge $2.00 an hour. Hmmm let's do some math. I may be incorrect in my calculations but it takes about 6 hours to charge a Karma at one of those, so basically $12.00 to obtain a full charge. On a full charge I'm getting 35 real miles in my car under normal driving conditions. So basically if I charged my car at a charging station I would be paying 34 cents per mile. Currently right now gas in my area (TX) is $3.16 a gallon. If I decided not to use the charging station & just run my ICE it would cost me 14 cents per gallon (this calculation is based on 22mpg running on ICE mode). That's less than half the cost to goto a charging station. If u were to break it down, if u went to a charging station, it's equivalent to getting 9mpg! My V-12 Lambo gets better mileage than that. So why would anyone want to goto a charging station???? Other than the fact they want to be Eco-friendly of course. Again my calculations may be off which would throw this whole thing out the window
