instead of using copper in a silicon chip, replace the copper
with fiber optic cables. at each end is an LED, and data can
be moved back and forth in the traditional manner. an entire
computer built this way (with analogs for resistors,
capacitors, etc. I'm sure) would not only be marginally
but would be much more efficient and would never overheat.
it might even be slightly cheaper, since I'm sure that glass is
cheaper than copper.

||How would you get the LEDs and optical fibres small enough to compete with etched silicon?
||Optical computing research is well advanced, using photons instead of electrons entirely; ie: not using LEDs and converting back-and-forth between electrical and optical.
[M-F-D] - old news...?
||What [neutrinos shadow] said. This is a brilliant idea, and
would have made you a pioneer a very few decades ago.
||Don't quote me on this but I think the slew rate for a LED is too slow. [ ]
||Decades ago, for classical computing, this research failed, for many reasons. Now with quantum computing, it is failing again. Bottom line - light for communication, electrons for storage and for computation.
||Whats needed is a purely optical-domain switch.
Until that happens, optical computing is a hybrid
bodge, or compromise to use the proper
