What about the rest of the history?

Oh boy, Asianometry… let’s see what he gets wrong this time! (While that guy’s enthusiasm and productivity is great, the quality of his research is often lacking. I don’t think I’ve seen a single video of his that didn’t have some glaring error or an omission of something that would have disproven his claim.)

 CCD and CCD imaging was an American invention!

George Smith and  Willard Boyle,  invented the CCD  at  Bell Telephone l Laboratories NJ, 1969 —

Awarded the  2009 Nobel Prize in Physics,

 CCD was developed  for imaging  by Michael F. Tompsett,   at Bell Labs, in the 1970s.

So…
- confused photoelectric and photovoltaic effects
- confounded CCD memory and bubble memory
- mixed up camera shutter and iris
- claimed the CCD’s power consumption was why early camcorders had short battery runtime

Back when camcorders used tubes, I'm sure the first CCD camcorder would be marketed as having very good battery life.
Cryptocurrency has taught me to love math and at the same time be baffled by it.

Cryptocurrency lesson 0: Altcoins and Bitcoin are not the same thing.

Probably. But I kinda suspect that all the other stuff involved in an early camcorder — a CRT viewfinder, a tape transport, etc. — and the limitations of pre-lithium rechargeable batteries would probably end up being the deciding factor, not the sensor type!

We used CCDs for Sine & Cosine Convolvers as part of the Chirped Z Transform based portable handheld Real Time SA developed back ~80. Back then we had a custom CCD process, and these custom CCDs had very large clock capacitances (recall 4 clocks, 2 had large C and 2 had moderate C). These clocks needed to swing >15VPP at a high rate which would produce a very large chip clock driver power dissipation and might be why the early CCD imaging chip based cameras consumed high power (during readout).

Anyway, we developed a clocking scheme called "Reactive Clocking" which exchanged the capacitive clock energy stored in the chip clock capacitance with the power supply, similar to a boost regulator, which saved ~95% of the power of a conventional clock driver (we should have patented this but didn't, and ~ decade later NASA did, altho for a different application!!). Without the Reactive Clock our handheld SA would require a couple deep discharge DieHard Lead Acid Truck batteries :P

Best,
