Parabolic to fiberoptic
Main > Energy > Solar Power
Jeffery Gordon has proposed and constructed prototypes for arrays of small parabolic dishes concentrating sunlight into fiberoptic cables. a 1 mm diameter cable can carry about 16 watts (due to the limits of concentrating ability) of sunlight into a nearby lab where it may be used for various processes.
The advantage of this setup is that the array of small dishes can track the sun like a flat panel collector, and do not require huge support structures. Also, the sunlight can be used in a controlled environment, rather than precariously at the top of some large structure. This enables such things as the creation of nanostructures through solar ablation and surgical procedures with beams of sunlight rather than lasers. Both of these have been accomplished by Dr. Gordon. The controlled lab environment would also allow things like solar thermochemistry and solar upgrading of hydrocarbons.
The concentrated sunlight could also be used to purify water
