Do something like mid-air refueling. A truck with a huge battery pack pulls up beside you on the highway and recharges your car while you drive. Eliminates the need to build recharging stations everywhere. And since your million dollar electric supercar no doubt has self driving, you don’t need to take rest stops. Except I guess to use the bathroom. I’m sure they’ll work that out.
I would say if you’re not going to drive, why not take Amtrak or Greyhound. Except then you have to mingle with THOSE people. Plus I guess you need a car for short trips when you get to your destination. If you believe everything they say about the next generation where the future is going, nobody is going to own cars anyway. They’ll take an Uber, or if they need a car to drive for a few days, they’ll rent one. Maybe an electric supercar! So rental fleets could be the target market.

For 99% of what we do with cars, needing to recharge for 4-8 hours every 300 miles or so, really isn't a problem... you drive to work, drive home, plug it back in and tomorrow it's ready to go again. But when you want to go on a 400 mile trip, you just can't do it - you're going to have to stop somewhere in the middle for half a day to recharge. Since there are limits on the number of hours a truck driver can drive in a day, I imagine that it would be possible to make it work with a big enough battery pack, and recharging stations in the right places... for things like police cars and taxis, you're not typically going far from where they're based, so just switching cars would be a realistic option. Granted, not a cheap option, but the difference in the cost of fuel could very well make it cheaper than burning gas. But if you can make a car that can be recharged practically as fast as filling a gas tank, you don't have to worry about any of that - it's just a matter of building the recharging stations, and they can be used the same as gas/diesel vehicles are used now. I think the idea of building a luxery supercar, is that you can show that it works, and you don't have to worry about how much it costs. There's nothing practical about a supercar anyway, so the practicality of it really doesn't matter.

If someone is really concerned about recharging their luxury supercar in 4 minutes because they’re driving it cross-country or something, they are going to have a problem finding the special charging stations. If instead they’re just Matthew McConaughey wanting to take their Lincoln out on a spur-of-the-minute drive in a commercial, I doubt he needs to recharge it in 4 minutes (or that there’s a special recharging station on his route).

I don't know what a short on a 100kwh equivalent capacitor would look like. Probably looks like a bomb. On 3/5/2019 10:11 AM, Mark Radabaugh wrote: Perhaps some type of supercap instead of a battery? That’s about the only way I could see truly fast charging time since you are not using a chemical reaction, just storing electrons. https://cleantechnica.com/2018/02/27/supercapacitor-research-promises-10-minute-charging-times-200-mile-range/ Safety should be interesting. That’s a hell of a lot of energy density with very little to rate limit converting it back to heat - talk about the potential for a really big boom.
