The issue is energy density I believe. But they solve the "refuel as fast as a gasoline vehicle" issue.

I also don't think that electric vehicles will supplant more than 60% of the vehicle market long-term (if markets were unfettered).

I don't see any way it will reach 60% unless most vehicles are taken off the road due to the gov't. I bet at 10% the fail will be so extreme it will end.

The dream is to eliminate personal ownership of vehicles for all but the extremely wealthy.

Eventually self driving vehicles will be 99.9% of the market to "save lives" and "increase efficiency"and it will be common to subscribe to ride-share programs where autonomous fleet vehicles deliver workers to work.

This will only happen after the vehicle manufacturers and owners have immunity from liability in accidents involving the vehicles.

Fear not though, you'll still be able to go wherever you want as long as you can walk there, or it's allowed. Unless you are extremely wealthy and can afford the jacked up insurance rates for owning your own manual (steered, which will be the new "manual") vehicle.

Some thought that horseless carriages were just a passing fad, and more than one investment expert thought the Internet was a poor investment. If you don't know what this has to do with that then it's not for you.

It seems unlikely that cars running on Li-Ion batteries will ever overtake gas engines, without massive government intervention. Lithium is a rare metal, and it's expensive to convert into batteries. Only something like 2-3% of cars worldwide run on electric now.

Maybe one day batteries will get better and be cheaper, because the entry level cars now that can only go 200 miles and cost $50K just isn't very competitive.

Diesel electric trains are good. Electric motors and transmissions have advantages. I wouldn't be surprised to see better hybrids or straight up fuel/generator systems or fuel cells. You're right that batteries are the problem. The drivetrain side of electrics is awesome in everything from ships to trains to aircraft. It's the batteries holding us back.

I somewhat agree. SC would best be used on a regular combustion vehicle to capture energy. Some reason non of the manufacturers have done this in any significant way. Makes too much sense to have rwd gas and fwd with supercaps.

Another issue is the amount of power needed to fuel up an EV with the same power transfer as gas, it’s massive and would require major infrastructure.

Lastly, the whole climate change and energy crisis is a farce.

The ONLY way batteries will ever work is if they are removable. then you can pull up to a station and exchange them

This is not in the consumer level yet.

Technology always moves on and one day I can see something electrically powered replacing the car. What we have today though for electric cars has to many negatives to replace the good stuff we got with petrol powered vehicles.

look up skeleton batteries. they just announced a few weeks ago a quickcharge (60seconds to charge) cell that will power large construction vehicles for 20-30 minutes.

pretty great! the research is already expanding

Supercapacitors have come a long way in the last 30 years. It's possible that we'll see "battery banks" made of capacitors instead in the next decade.

I agree. The technology is progressing in that direction. Wow Amazon has a 3K Farad cap for $70. That'll shock your shit senseless if not cateful.
