Sun Scoop solar concentrator made with Cone Solar method.

The Sun Scoop is a parabolic solar cooker. It is part (not a full dish) because this makes it easier to reach the cooking material. I made the dish to be approximately 1.5 sq meters of collection capacity. This was so that it could be compared with a SK 14. I made it with the "cone solar method". It has tracking by rotating the reflector on equatorial mount. I used the cone method because it was fairly easy to do, and because there was very little material loss to cutting. I used 8 cones and about 3/4 sheet of 4 ft by 8 ft (1.2 m by 2.4 m) to make the Sun Scoop in 2025. The cones are designed to make a focal ball that is about 15 cm diameter. This was sufficient to boil water, and to steam soil. Having learned from 2025, I think the best thing is to cut the 4ft by 8 ft sheet in half and make two of 4ft by 4 ft sheets. Then cut the cones from them. I include measurements to make a sun scoop with approximately 1.1 or 1.2 sq meters of collection area and a choice of a 15 cm ball of heat, made of 7 cones or one with a 10 cm ball of heat and made from 11 cones.

Here are the cone dimensions. First is the 7 cone dish with at best a 15 cm ball focus.

1. Cone 1 159 cm and 137.5 cm
2. Cone 2 128.75 cm and 109 cm
3. Cone 3 101.5 and 83.25 cm
4. Cone 4 78 cm and 60.5 cm
5. Cone 5 57 cm and 40.5 cm
6. Cone 6 39 cm and 23.5 cm
7. Cone 7 22.75 cm and 7.75 cm

The 11 cone dish has a tighter focus as good as 10 cm ball of concentrated light.

1. Cone 1 163 cm and 148.5 cm
2. Cone 2 141.75 cm and 128.5 cm
3. Cone 3 123.25 cm and 110.5 cm
4. Cone 4 105.5 cm and 93 cm
5. Cone 5 89.5 cm and 77.75 cm
6. Cone 6 74.5 cm and 63 cm
7. Cone 7 61 cm and 50 cm
8. Cone 8 48.5 cm and 37.75 cm
9. Cone 9 37 cm and 26.75 cm
10. Cone 10 26 cm and 15.75 cm
11. Cone 11 15.5 cm and 5.25 cm
