This article is sorta old (1.5 weeks) but quite interesting Slashdot - Nanotube RAM 1 TB per square centimeter. Wow. Imagine, an entirely solid-state computer with reams of memory, near-zero boot time, and capable of running oodles of progs at once. Couple a piece of this memory the size of a poker card with a parallel CPU array, and you'd get... The GX Tower (or pizzabox). *Twilight Zone music* BUT... I don't know too many details about information entropy, but wouldn't rewriting/permanently erasing such a RAM disc create a WHOLE LOT of heat? Can someone who knows a bit about this share with the rest of us?
