| Satellites are overdue for a planar technology makeover. Your smartphone contains more transistors and advanced technology than a three hundred million dollar satellite, and replaces a complex wired network with a distributed cloud of small cooperative devices. Deep submicron MOSFETs and micron-thick InP solar cells do not need radiation shielding. Speculative branch processor pipelines can be adapted for error tolerance. Combined with other new technologies, such as electrochromic mirrors, flat screen technology, and automated solar cell production, we can cheaply mass produce tiny satellites by the billions, and launch them millions at a time.

Server Sky - Solid State Data Centers in Orbit
Satellites are overdue for a planar technology makeover. Your smartphone contains more transistors and advanced technology than a three hundred million dollar satellite. Satellites are 99.9% packaging by weight, and cost far too much to launch. What if a "satellite" was more like a cloud of smartphones instead of a 1970 telephone central office switch?
Server sky is a speculative answer to this question. Deep submicron CMOS and micron-thick indium phosphide solar cells are inherently rad-hard. These and other recently deployed technologies enable "thinsats", 50 micron thick gram-weight satellites in large arrays, converting megawatts of PV output into computation and microwave communication.
The sun wastes 380 trillion terawatts on empty space - if we can use and dissipate a tiny fraction of that power on our mass computing needs, we can continue growing computation markets without expensive infrastructure and environmental burdens. Moore's Law, which is really a promise of exponentially increasing capability per dollar, can continue into the far future.
