Look, if you believe battery technology has reached it’s technological capabilities and has hit a wall, I can’t help ya. If ya do some research you’ll find battery technology is being developed and improved all the time.
Suggest you go back and re-read what I posted with a fresh set of eyes, specifically my posts #68 and 69. Not saying it's "not possible." Am saying it's going to take a long time based on the last "major advancement" being 25 years ago.
Look, I personally know several folks at Argonne National Labs. (Suggest you google Argonne National Labs.) They received a substantial Government Grant to do the very thing I posted: a "Manhattan project" for the next battery technology. The announcement they received the funding was HUGE, made national news. (Perhaps you missed it?)
These are people who are "true believers" in green energy/green technologies. THEY SAY it'll take potentially several decades to advance battery technology to where it needs to be, which is longer lasting, quicker charging to compete with conventional hydro-carbon fueled engines. In their words "they have to invent the technology to invent the technology" to make the breakthroughs they believe they already know must happen.
Now if you put Takehisa Yaegashi's (inventor of the Prius for Toyota) comments in that context - he's exactly right that conventional gasoline and diesel engine technology will surpass battery based vehicle technologies in achieving new efficiencies.
If it's not obvious to you that's true, suggest you look at average vehicle MPG over the last 40 years vs. battery lifetime and technology over the last 40 years. There's no comparison which technology is advancing faster. Any reasonable person with a basic understanding of the two technologies can see that. The data's on the internet if you care to look.
