He estimates 250W, but that seems low - especially if the gates have resistive pullups.
But, there are more than the minimum number of transistors in the gates, so maybe he's doing something different, perhaps more like CMOS. He has 10 transistors for each bit of RAM - that's more than the minimum, even for a static RAM! But I think he also says that all transistors are the same, so it's a bit of a mystery.
AFAICT, he's using MOS with pull-ups, not CMOS, limiting his clock rate and using a lot of energy heating the pull-ups for every logic 0 in the mix.
