* The disk platters normally live in a semi dust-free enclosure. Using them under semi-harsh conditions where heat, weather and PM10 or PM5 conditions is to be discussed. From november 2011 to march 2012 a platter will be actively exposed to the harsh conditions the Antwerp Ring poses to 100.000 living under less-than 500m distance. The disks are dead OK, but the sputtered reflective surface might deteriorate seriously.

Idea

An experiment with recycled hard disk platters, which are excellent no-cost reflectors for sun light. A solar cooker is developed by building an array of mirrors to aggregate light to a focal line or point. The energy can either be focused to a cavity or transferred to store the heat elsewhere to drive a generator a Peltier element, or other stuff.

Some reference ideas

Calculus

((95mm-25mm)/2)^2 *PI = 0,001225 * 3,141593 = 0,003848 m^2 = (3.8 x 10-3)

Layout

A compact linear fresnel reflector-array is easy to adjust to the earth motion. Packing circles in squares

Tracking

Help with some arduino-project with some suntracking software a stepper-motor and we are all-set. Oh, some wood working is needed, please wheel in some euro-pallet please.
