Q: W1 chip technology

Here is all that is currently available. http://www.apple.com/airpods/

Apple has not posted specifics, you would need to find a technical journal and some of the technology maybe proprietary and Apple is not going into detail yet, or ever.

I would be interested too, but all that is there, and what was in the keynote is everything everyone knows right now. And, as Jimmy has said, I suspect there is a great deal of proprietary information, as well as patented IP that you won't get to learn about.

I don't think it is, most people don't know or care to know how an internal combustion engine works, and the vast number of them own a car.

Just do a simple internet search. Engadget, CNET, EE Times, PhoneFaq.org and only about another dozen other tech. news sites have multiple articles on the W1 chip.  Read those and you'll know as much about it as anyone here could know.

Apple itself is extremely unlikely to release great details of their proprietary chips and technology.  You won't find detailed information of the new A10 mobile CPU either, not from Apple.

Bottom line it is still standard Bluetooth. The W1 chip is NOT some new protocol or wireless technology. It’s an enhancement of regular Bluetooth. Your statement about “harmful Bluetooth” makes me think you imagine you have a health issue with Bluetooth technology. That’s nonsense.
