You are right, but technology is moving so fast...Although I disagree with the OP I have never seen a charge station run on gas..
I am not a Hi tech guy, but I see these solar panels all over, like google ... Little tiny cars on the freeway ( I would never drive one)
The Future of Solar And Electrical Vehicles
Students design a solar-powered car that can travel more than 600 miles fully charged
Despite the limitations of batteries, the tremendous efforts devoted to research have resulted in technological breakthroughs in the development of batteries and EV prototypes. The energy density of the batteries has been extended up to 200 Wh/kg in lithium-polymer and zinc bromine batteries, a level far greater than the typical value of 40 to 50 Wh/kg for lead-acid batteries, but still far below the energy density of gasoline (Oman and Gross). The typical limited driving range of 100 miles between recharging has been surpassed by the BMWE2, which traveled 267 miles on a sodium-sulfur battery, (O'Brien, 41) and German postal trucks, which have a maximum range of 186 miles and can obtain a top speed of 66 mph (Oman and Gross, 29). There have also been improvements in recharging times and lifetime of batteries. "Quick-charging" batteries can be recharged on the order of five to fifteen minutes, depending on the level that they have been drained, though these batteries are still highly experimental (ABCs, 36)
None of the "hopey" stuff you posted is really impressive. Samsung pushed "energy density" in battery packs to it's logical flame out. It's not the weight or size of the batteries that is the problem, it's the cost and LIFETIME.
Have you SEEN the car that those students designed? I did.. It's a bike frame with a fiber shell. NOT a car. Good for students. Kudos. BAD for an honest appraisal of how fast this technology is gonna grow anymore. It's pretty much matured. Otherwise some MAJOR auto factory would be PROJECTING higher ranges.
Better chance of saving gasoline is NOT to use the grid at all to replace it. Hydrogen fuel cell cars DO have a lot of room left for improvements. And several majors are prioritizing them HIGHER than battery cars. And you can make Hydrogen for virtually NOTHING off grid with wind and solar and store it. It's a better SYSTEM design..
Like I said, I am not a hi tech guy.. and from what I have been reading you are correct..
We are in the pioneer stage though , exciting too.
But...will you agree that they do not use gas like the OP suggests?
That's the point. We are NOT in a "pioneer stage". Not with PV solar panels and not with EVehicles. It's a fairly MATURE technology. Where there might be some "specialty" products that are not as cost or safety sensitive.
Solar panel tech. ITSELF has hit a plateau. It's the Manufacturing engineering and market scale that is driving costs down. That student car is largely a PR stunt. The "panels" on the vehicle aren't doing much. Especially not the way they slope back on the car. Only 1/2 of them are ever in the "prime angle" to capture sun during the day depending on which direction the car is driving. And they would almost DOUBLE the production cost of the vehicle, make it IMPOSSIBLE to Insure for collision, and probably BLIND other drivers in traffic with reflections off of the roof.
