Server Sky - internet and computation in orbit

It is easier to move bits than atoms or energy.
Server Sky thinsats are ultralight films of glass that convert sunlight into computation and communications. Powered by solar cells, propelled and steered by light pressure, networked and located by microwaves, and cooled by radiation into deep space. Arrays of tens of thousands of thinsats act as highly redundant computation and database servers, as well as phased array antennas to reach thousands of transceivers on the ground.
First generation thinsats are 18 centimeters across (about 7 inches) and 0.05 millimeters (50 microns) thick, and weigh 3 grams. They can be mass produced with off-the-shelf semiconductor and display technologies. Gallium arsenide radio chips provide intra-array, inter-array, and ground communication, as well as precise location information. Thinsats are launched stacked by the thousands in solid cylinders, shrouded and vibration isolated inside a traditional satellite bus.
Traditional data centers consume almost 3% of US electrical power, and this fraction is growing rapidly. Server arrays in orbit can grow to virtually unlimited computation power, communicate with the whole world, pay for themselves with electricity savings, and greatly reduce pollution and resource usage in the biosphere.

Server Sky is speculative. The most likely technical showstopper is radiation damage. The most likely practical showstopper is misunderstanding. Working together, we can fix the latter.
