Nanofactory Design

A coolant consisting of suspended encapsulated ice particles can absorb 1.2x10^8 J/m^3 (Drexler, 1992, sec. 11.5), so less than 2 liters per second of this coolant would be required. This will be divided among many linear channels. Figure 5 shows small 1x16 micron coolant channels left open in Stage 1. As Stage 1 components are stacked to make
