CM1 had 65536 single bit processors. They were not connected in a crossbar, instead the chips that were the fundamental building block of the supercomputer each contained 16 of those bit serial processors and 4096 of those chips were connected in a 12 dimensional hypercube. The total dimension of the hypercube was 16 but the 16 on-chip processors had local routing.

The smelted aluminium goes to the market, recyclable aluminium from scrap is recovered and fed into grid scale aluminium air batteries (still in development) and you have got a closed loop of generation and storage.

This seems very much like the Disruptor[0] pattern implemented in hardware.

Transmeta tried to do exactly what you are proposing i.e, have a software layer (Code Morphing) translate the x86 instruction stream to their native VLIW instruction set. They didn't go very far.

This is possible because of the electromagnetic signature generated by the processor's clock circuit while it is decrypting the data. The microphone is listening to the EM signal generated by the clock and timing the samples to reconstruct what the processor was doing. This type of attack is very difficult to carry out against a completely asynchronous or self-timed circuit that doesn't generate timed samples due to the lack of any central clock.
