electric cars are a niche market
And will be for a long time.
In high-density cities, real estate costs and lack of sufficient power grid will eat most of any profits.
And the always fun permitting bureaucracy.
You live in a 40 unit apartment and they installed a charger in the parking garage.
Why isn’t that sweet. (They took gov assistance it has to be open for PUBLIC USE)
“There are plugin hybrids which have 100% electric modes”
That sounds like a great idea.
When electric cars eat into gasoline consumption they’ll put a road tax on the electricity used for cars. The road tax on gasoline is currently around 50 cents per gallon.
The electric drive-train is just fine. The battery as a source of power is the problem. A fuel cell which could process hydrocarbons would be better still. A not-demoed-for-now electric power source perhaps optimum.
WrightSpeed went the series hybrid route with a gas turbine driven charging system feeding a battery bank. Placed in a wastehaul chassis, it transformed the vehicle fuel consumption by tripling the mileage.

“Conventional battery powered cars will never be the future”
Can any physics experts out there tell me if this is theoretically possible? At some point in the future a super strong battery is developed that can be recharged on the fly, the electric car motor turns a super strong generator so the battery is constantly replenished with voltage and never drains while the car is running, giving the car the ability to run indefinitely without having to stop and recharge. In theory more energy would be produced than consumed. Just wondering if that might ever be possible.
What you describe at least partially defies the laws of physics as they are understood. Could some machine continuously draw hydrogen or nitrogen from the atmosphere on the fly? Perhaps.
You may have seen a recent report of a crop of corn in a remote mountainous Mexican village which self fertilizes by drawing in nitrogen from the air and creating a globular form as it’s own source of fertilizer. For some time geneticists have sought to construct such a plant and only recently discovered this as a non-GMO, naturally occurring plant.
So, could something similar be translated from an organic application into a mechanical application? Who knows at this point, but creating any machine with an output greater than it’s input has long been thought to defy basic laws of the universe.
The big problem:
Technically you can connect your Tesla to a standard 110v plug receptacle with the free adapter that comes with the car. But you can only charge slowly–at about 3 miles of range per hour parked. ... It will take up to 4 full days to fully recharge an empty Tesla car battery using a regular wall outlet.
Nightly Charge Time 1 hour 45 minutes
Range per Hour of Charge 29 miles
Power Level to Vehicle
50 amp circuit breaker 40 amp load
I understand what you are saying.
I believe that Japaneese engineers in a gasoline challenged nation will solve the problems if they deem it economically feasable.
I have a 2015 Toyota Camry hybrid
496 miles per tank and averages 40.7mpg
The existing battery technology will continue fall in price and density will increase and it is possible new technology could speed that up.
Eventually electric cars will be cheaper than fossil fuel types, but nobody can say for certain when.
Exxon says 2045, but most say 2035. Some say that by 2025 there will be enough electric cars on the road(China) to begin distorting the oil/gasoline markets.
No. They will not make money. They will TAKE your money...even if you don’t own one. Without “subsidies” from taxpayers, they fail.

Elon Musk has spent billions up that dead end street.
Its total Bull$hit.
There are still smaller state subsidies in California, Texas, and perhaps other states.
It has to be done before the factory batteries expire and have to be replaced. The amount of toxic waste and cost of disposal will double the sticker-price shock (that came even with govt. subsidies). Try selling a $40k+ car used when it will cost several grand to replace battery. Last year the list price of a Volt EV HV battery pack wass $15,734.29. Plus installation. And now there seems to be no limit to fossil fuels due to fracking improvements in the past decade. Texas actually exported, rather than imported, more oil for the first time in history this month.
“In theory more energy would be produced than consumed.” Uh...no. That’s impossible. A motor being powered by a battery cannot at the same time run a generator that keeps the battery charged. That’s the stuff of comic books or Rube Goldberg cartoons.
It you weren't so dumb you would know that the Volt is a PHEV
Leaf, which is an EV, recently announced rebuilt batteries for their older models at $2850.00 installed plus trade in of old battery
Electric cars make a lot of sense, but they have one major obstacle — no 3rd party has created an infrastructure to support them.
Imagine how well gasoline cars would do today, if there were no gas stations.
Cars are actually an excellent application for electric motors, which provide a more efficient conversion of energy to work. By using electric intermediary, cars can be powered by multiple different energy sources, including nuclear and hydro power.
But since the gasoline infrastructure is in place, it is hard to switch over to what could be a better end product. Few can afford to invest in fast-charge stations and capabilities for the small number of customers, but few people can buy a car and use it when there are so few places to recharge.
But, like electric deisel trains, and the increasing use of hybrid electric solutions for commercial transportation needs, over time the more efficient, cheaper, more easily maintained electric conveyance should become a major part of our total transportation infrastructure.

In high-density cities, real estate costs and lack of sufficient power grid will eat most of any profits. (from charging stations)
And the always fun permitting bureaucracy.
Perhaps a charge on the go/ metered in the vehicle scheme?
They are working on it mightly, outlook uncertain.
The old square of the distance thing and ground clearance, among many hurdles.
My typical daily drive was 60 miles round trip.
~20 Kw/hr per day ~600 per month, just one car, we have more.
The average home uses ~900Kw/hr.(yes a very simple view.)
How much overcapacity is built into the grid; if any?
EPA rated the 2017 90D Model S’s energy consumption at 3.096 miles per kWh
In 2016, the average annual electricity consumption for a U.S. residential utility customer was 10,766 kilowatthours (kWh), an average of 897 kWh per month. Louisiana had the highest annual electricity consumption at 14,881 kWh per residential customer and Hawaii had the lowest at 6,061 kWh per residential customer.
