All good points. (And my figure actually assumes 10x faster and no loss of time between clearing wells and capturing photons -- i.e. 90% of time is spent capturing photons and 10% is spent clearing the well with no downtime -- to be generous. And, again, just to equal current performance.)
The underlying idea is sound -- storing bits is a linear problem but storing photons is an exponential problem. Of course you're still going to have to dump exponential amounts of energy... (So forget the "unbounded" part.)
- paulmd 11y agoYeah I was thinking that too. No matter how tiny a capacitor, you have (tens of) millions of them on the sensor, one per photoreceptor, and you're charging and discharging them 100k-10M times per second. That's a lot of energy being accumulated and dissipated right next to the photoreceptors. Thermal noise is gonna be nuts on a modulus sensor, too. No system is ever unbounded, period, unless you live in a world of frictionless spherical cows. At some point you run into issues caused by accuracy, energy, capacity, etc.
- gohansan 11y agomaybe that energy can be used to recharge the battery
