Wouldn't that put battery power density up there with petrol if this were accomplished?

the oil/gas industry will never allow electric cars to be mainstream..

actually I don't think they could stop them becoming mainstream if the governments made it law that they become mainstream.
Judging purely by many governments reluctance to spend much more on renewables beyond a meaningless token gesture, I bet the real barrier is the governments.
For example, we have for here in the UK
http://www.independent.co.uk/news/uk/politics/government-fossil-fuels-renewable-energy-uk-export-finance-climate-change-global-warming-co2-a7887376.html
and compare that with
https://www.ukpublicspending.co.uk/uk_defence_spending_30.html
So not only does the UK spending on weapons dwarfs that of its spending on energy, its spending on fossil fuels is much greater than that of its spending on renewables.
This shows the true unofficial intent of the UK government; business-as-usual and **** the future of humanity because we don't care.
