I saw something about this last week.
The university publication said 6 years before they might know if it could work, another 6 - 10 after before commercial quantities might be produced.
And in the meantime the Chinese will steal the patents and put the new technology to work . . . at a deep discount.
Give the job to Elon Musk and he’d probably have production rolling by end of next year.
“6 - 10 after before commercial quantities might be produced.”
Like fusion, always 10 years away.
