Battery tech and range

Re: Bulletin of the Atomic Scientists.
Should chemists ever bring something like this to fruition,we'd be looking at a Tesla Model S with a range of 2,796-miles,to,4,194-miles on a charge.

Even half that with 80% efficiency, would be killer.

I am still thinking that super/ultra capacitors combined with batteries will improve cars, mostly for regen and starting from a dead stop (or hard acceleration).

Tesla has already purchased a super capacitor manufacturer,and has an up-coming meeting/announcement, about the hybrid energy storage system,not too far off now.
Back when the EV1 debuted,seems like Honda was already using the state-of-the-art Russian super-capacitor in their little SUV EV.

People would still claim range anxiety.

How long would that take to charge?

50kw is practical.
So an insane super 1mwh battery would take around 20 hours to charge.
I will be all set with a 62kwh battery. Charge it every 2 or 3 days during the summer, probably every other day during the winter.

Yes, many people think Tesla bought Maxwell for their dry catalyst technology, but I think they wanted them for that and the super capacitors.

As far as I know, Maxwell makes the best supercaps, and they cost a fortune. The best one goes for $90, and it's just aluminum and carbon (and probably other things, but the materials cost is low). I think the potential applications for supercaps as they exist now are mostly untapped. There's room for innovation in that sphere, and that's what Tesla does. Bring in economies of scale, and we might see supercaps in a lot more things.

No mention of it.I presume that,with this sort of range,you'd charge overnight at your final destination,as you would at home.A couple hundred miles range/hour would do quite a bit overnight.A weekend's charge on holiday would be good for a New York to Los Angeles trek.Non-stop if your bladder was up to it.

range anxiety ends around the 500 mile mark charging stations is the issue i don't want to wait 30min to charge it up

(unless the car could drive it self there)

(charging up at home is not really an option unless the complex i live adds charging stations) they could upgrade the solar panels to add such a thing there is not a single electric car here and hybrids there is only a few of them

we would have to run a 100ft electrical cord to get 240v

I think apartments will add charging points like they did cable and internet. Drag their feet until the competition adds it. Once people are moving to locations that have these features, then the apartments will have to add them to compete to draw back tenets.

Not going to be as quick as we all know it would be possible. Battery storage (and maybe PV if the orientation/hours of sunshine make that feasible) and some connectors, plus a connection to the grid.

If in a location that has a highly differentiated rate for power (from day to night), it could be a source of income for the apartment. recharge at night and if by mid-day to late afternoon still have over 50% battery, sell it to the grid until down to 25%, then charge that night... with self adjusting algorithm, it will dial itself in and more so with PV, as that would give even cheaper 'rate' for charging the battery.

Plus, they would be able to put a surcharge on the power those tenets consume...

But most apartment owners will not want to be first, so it will take new construction or a landlord willing to gamble.
