Newer LEDs are surprisingly bright at low currents.
The forward voltage, however, is a hard limit.
By sheer coincidence, I used a circuit to get enough voltage for a green
LED from only 700mV as proof-of-concept for wine:

(by the way, Plone still doesn't work quite right, *&[EMAIL PROTECTED])
but you'd need an AC waveform for the charge pumps to work.
It's not easy at all to build a DC to AC converter that works from
700mV.
Ah, a classic voltage multiplier. I see you are using Schottky diodes
for the low Vf. But the problem for Lan is going to be the pulse
generator. That will be a more interesting circuit. Or maybe we need to
go way back in time and use a mechanical chopper circuit :)
