hello!
my idea to reduce supply voltage is to use germanium transistors. they have a knee-voltage of ca. 0.2 v, so supply may be about 0.4v without saturation.
an idea to prevent saturation ist to use valve diodes with a reduced heating voltage so the knee voltage is less (diode valves have a negative knee voltage). so i think its possible to further reduce supply voltage to 0.2..0.3v.
shurely, ge-transis are not welcome today, because they have more parasitic current loss (this is because device death temperature is about 90°C). but this problem can be solved by freezing down the device with forced cooling to eg. 0°C.
you may probably think my ideas are a bit funny or esoteric, but i like to discuss about unconventional things, often they have a solution to provide standard technolgies with new features.
