I don't know the solution. Seems like a major investment in battery research is called for. Electric cars should also have a back up battery to get you to a charge station or home if you miscalculated your range.
If Tesla can succeed in better batteries, maybe they could supply batteries to Samsung.
If it was the Koch bros who were into EV's there would be one in every garage by now but today oil and coal obviously are still more wealth creating industries than EV's.
The day will come (and it's approaching very quickly) when free solar power will take over the country's energy needs. The proliferation of solar panels on rooftops today vs just a few years ago is amazing I even have them on my camper! The only thing holding back an almost complete turn around from fossil fuels to solar is the fossil fuel lobby but in the end they will lose. When was the last time you lit your home with gas lights or ever whale oil? Who buys incandescent or halogen light bulbs any more? Even fluorescent bulbs are being replaced by the LED revolution and are rapidly becoming passé.
It is possible that development of brushless motors could make the wheels the motors. That could eliminate transmissions making the EV more reliable. The electric motor starts out being reliable. Additionally whatever is holding back safety development could be overcome and EVs could eliminate vehicular crashes and accidents.
"No fat ass repub's would profit though."
There it is.
EVs would stress the system. Constructed of very few virtually lifetime lasting parts they would eliminate millions of jobs. Additionally if the EVs were allowed to be programmed to avoid accidents and injuries you now have to deal with trial lawyers. Note how many new vehicles offer life saving collision avoidance at extra cost but mileage is mandated by law for all vehicles. Collision avoidance should be #1 priority and required by law. Billions are spent on crash testing when crashes could be easily almost totally eliminated.
