Manufacturing was completed over a period of weeks. Various innovations were integrated into the design utilizing components from disparate industries.
=== Feed water flow control ===
Flow control was managed first by an IV drip system hacked together from low cost medical technology. A filter to filter out large particulates, a mechanical drip controller and check valve to keep the flow consistant. This was connected to the fiberglass formed 5 liter reservoir with a small elbow joint piece glued in for the outlet.

=== Absorber ===
Absorber is the same as previous. 3mm aluminum sheet with resin infused with charcoal coating
===Optical Cover===
This prototype used 3mm polycarbonate for the cover. It is considerably reflective so need to source better quality with anti reflective coating. It also scratched very easily. I first had it mounted inside the frame but this caused it to touch the absorber plate behind it. This created thermal bridging further diminishing the performance. So I mounted it on the outside.
The new reflector design utilizes a longer mirror array. This array is designed to provide more sunlight to the absorber throughout the day without the need to rotate the device. it folds up and is supported by string similar to the first prototype aswell as a wire kickstand. There is still some more modelling to be done

===Wicking Bed===
This issue turned out to be a kind of non issue. The wicking bed doesnt need to be watertight, it just needs to have a controlled flow of water to the wicks through an interface of otherwicks between them and the water flow. This was acheived by wrapping a sponge like wick in a peice of polycarbonate as the first point of wetting. this made the water spread out so that it would slowly wet the wicks mounted underneath. The wicks were mounted in a laser cut grill. they are threaded through and then fixed to the plates with the top and bottom dividers
