Anthropogenic Global Warming (AGW) now "Climate Change" drew the short straw!
And speaking of short straws, below find an image of the shortest of the lot!

150-200 pounds all-up fuel and tank for 20 gallons.
Tesla 85Kwh pack weighs ~1200#’s.
Are you claiming direct heat to electric conversion? Figure out the direct kinetic to electric equivalent required to recover a significant percentage. Battery won’t accept the needed charge rate for a 1:1 conversion.
Actually super-caps can respond to very fast charge requirements, but total energy density is far lower than a battery of equivalent weight.
The vehicle operational efficiency is always significantly higher as evidenced by the better gas millage. All of that extra weight doesn’t seem to be an issue.
No doubt there are times when a hybrid is way more efficient that a standard car.
Also, I wonder if the internal combustion engine in a hybrid has to work less, too since the electric engine assists the gas engine.
There are probably other wear out factors since the gas engine has to charge the battery sometimes.
Hybrids are still relatively new in their life cycle.
ROI is the question.
And all electric is a different story since it is charged by the power plant.
Yes, I would think they could be charged more quickly than a lead acid battery. Most batteries don’t like being flash-charged—there’s a loss of energy, and stress on the plate structure. Would it be a good combination? It might well be.
But, it’s hard to beat a man at his own game—I think battery designers may have thought of this. Maybe they don’t consider the super-cap technology mature enough. Maybe there’s another issue. Battery design is its own specialty.
Not necessarily so. Spend the extra money on weight savings and friction loss. Honda civic beats 40 mpg. Spend an extra 5k on skinny tires gear changes less steel and corresponding lighter brakes this and that and it could get past 50 easily.
Then it would be a cheap assed car like a. Prius but dooable

Of course they do. For decades the greenies wanted cars to practically put out cleaner air than they take in but now try to lie and say cars pollute more than coal plants.
40mpg in stop and go traffic? This is where the hybrid shines. The engine may never turn on and it is all battery if the speed is less than 30mph. No jack rabbit starts accelerate discharge the battery coast and break to a stop charge the battery.
In certain stop go situations they can be more efficient while sufficient charge is in the battery. In very cold weather they loose 2/3 of their range. At highway speeds there is no comparison, and on price without government subsidies there is no comparison.
“Investors tend to do the math and be pretty rational. There is no law against building more nuclear power, just no investors willing to get nuked again.”
There are, finally, some new plants being built in the US, of the AP1000 variety.
The real hope, though, is that one or more of the new, innovative nuclear reactor companies will hit a home run with meltdown-proof, easily secured reactors delivering power at 5 cents or less per KWH. These next-gen reactors don’t require water for cooling, which really opens up the siting options. They can also use “spent” fuel from older reactors, delivering the remaining 90% of the available energy there, and eliminating a lot of existing waste.
One such company is Thorcon Power:

Wind and solar won’t compete, if nuclear is allowed to play on a level field.
Maybe maybe maybe, the battery scientists are just like "climate scientists" solar developers and race baiters.
Battery design is its own specialty.
Just like the above specialists, they wouldn't want to actually solve a problem and see their lucrative gubmint funding-stream dry up.
“Maybe maybe maybe, the battery scientists are just like “climate scientists” solar developers and race baiters.”
Supercapacitors have one major problem - energy density. For a given weight, so far they don’t hold as much power as chemical batteries. There are some promising new developments involving carbon nanotubes and graphene, but it’ll be a while before availability. From what I’ve read, at best they will equal Li-Ion batteries. That would be a big win, as supercapacitors can endure 100x+ more charge/discharge cycles, and charge faster. We’ll see.

That’s nonsense. There’s billions if not trillions of dollars to be made. Battery technology has been steadily improving due to the same market forces.
Too bad the gasoline engine is so inefficient, too. The combustion process is extremely inefficient. Maybe improving its efficiency is the solution. Although, there basic thermodynamic laws that can't be broken.
Electric cars use the same process for recovering the otherwise wasted energy. HOWEVER, their original source of power is from the power plant which is powered by coal, nat gas, nukes, hydro....
Plus all electrics can be less reliable — as you mention. I'd prefer to get less gas mileage and get to where I am going versus the car running out of juice before I get to my destination.
The key is to improve battery technology.
Another thing that proponents of all electric vehicles fail to mention - the current power grid cannot support electric cars (if a large percentage of folks buy one). Ironically, the feds, Democrats are killing off viable sources of power all in the name of being green. The power supply is being slowly choked off. And no, wind and solar are not viable alternatives.
What if the electricity is from Natural gas, Nuclear, Hydro, wind or solar?
They really need to do two things.
Improve batteries removing internal resistance so they charge is minutes and don’t wear out and not susceptible to temperature fluctuations.
Also beef up the power grid so it can handle the load securely.
Using onboard gas engines to recharge and provide propulsion is complicated, heavy and expensive.
CNG is excellent but each fuel station costs a million or so for the pumps. 3000+ psi takes a fair amount of power on its own. E=MC^2
Dude. Where've you been?! CO2 is going to kill us all!!!
Nuclear,
Chernobyl, anyone? And where to put all that spent fuel...
Hydro,
HEY, fish are people, too!!!!
wind or solar?
Now yer just bein' silly.

The purpose of the solutions to climate change is a regulatory framework to enact global government. That is all.
LOL!!! Useless Pinwheels per Limbaugh.

Exactly. Well said.
