1.   He says that by packing molecular circuits very tightly and designing them for specialized tasks, you could run each device very slowly and still get huge computing power.

2.   Molecular circuits packed a million times more densely will get extremely hot-a processor could get as hot as a stove.

3.   One is to pack molecular circuits less densely.

4.   The HP work is not the only approach for assembling molecular circuits.

5.   Without that, the already faint signals in a molecular circuit could easily drop below a useful level.

6.   For a molecular circuit to really work, researchers need to have a way of managing the way the signals travel.
