Electric cars will always be toys for the rich unless the problem of quick charge is finally solved .
Quick charge and range. Having to plug a car in after only two hours use is a pain.
Have you heard of Store Dot Central_Va?
5 minute charge for a 300 mile range battery. They are from Israel ( yes they are a blessing ) they are using bio-peptides ( stomach acid(?) to accelerate the electrons into the battery, it makes sense if you think about it.

And then their is the 3D foam battery with a 5X storage capacity out of Colorado the Prieto Battery.

And this doesn't include the various aluminum ( alcoa etc ) batteries that might get us 10X from where we are.
The question begs, can some of these advances be combined, are their synergies.
We are also on the verge of the electric training aircraft, the Sun Flyer and the Proto has been delivered. I'd never thought I'd see it or say it, I think Electric Flight hasa better chance than Electric Cars....
People forget that battery energy deteriorates over a relatively short period of time. The energy in gasoline is not nearly as perishable.
