'''Joel Goodman''' is a research architect living in {{state|Wisconsin|Wisconsin}}. After a few solar cooking experiences in the 1970-80s, he began studies of small-mid size solar kitchens using built-in fixed ovens (2003), inserted solar box cookers (2005), and augmented with building size nonimaging fixed reflector troughs with adjustable end reflectors (2007)(2009). Because of outgassing concerns from materials (insulation, glues, etc.) inside of augmented box cookers, and box cookers take up space in kitchens, mid-size kitchen studies began with thru-wall greenhouse type (HotPotTM, etc.) ovens (2006), and recently for small houses with thru-wall greenhouse type ovens combined with improved cook stoves, revealing house plan and solar access planning requirements. Additional studies are for exterior furniture fixed reflectors augmenting box cookers.

*{{NewMay23}}'''May 2023: TRW small low-cost masonry house in the tropics studies''' - A TRW configuration favored at this time for small masonry house studies is an ordinary-CPC type funnel-box with horizontal inlet aperture, flat trapezoidal kitchen wall reflector and vertical E/W portable reflector. Cookware options in the funnel-box are placed on a ‘square’ reflector plate that defines the cookware door width and associated lintel. An option is a temporary transparent horizontal unsealed cover glazing on the funnel box inlet. A TRW with a large cookware door would coincide with a main TRW characteristic that is: large, heavy or cumbersome cookware too inconvenient to carry outside to a solar cooker in bright sunlight may be used by cooks inside a TRW kitchen. Cookware options that fit thru the door and fit on a ‘square’ reflector plate include: a large diameter cylindrical cookpot, multiple smaller cookpots, and a cubic black metal oven. Aluminum or flat glass mirror CPC-type reflectors are in the funnel-box. Flat glass mirror reflector tiles forming a trapezoidal shape on the kitchen wall above the cookware door are being considered. The incline of the trapezoidal reflector is influenced by the latitude location. Construction materials and methods could influence cookware door size and TRW funnel-box shape e.g., Compressed Stabilized Earth Blocks (CSEB) standard shapes and sizes.

*{{NewSep22}}'''September 2022:''' TRW Kitchen Wall Reflectorก TRW kitchen wall reflector details depend on the kitchen building wall optical shape related to latitude location and construction materials and methods. For example, flat glass mirror tiles on masonry, ferrocement or wood wall parts. A TRW kitchen wall shape may be vertical or near vertical to avoid overhanging reflectors near about 23.5 degrees latitude (e.g., about 17-27 degrees); and sloped near the equator (about 0 จC 15 degrees from vertical) with possibility of nonimaging one-sided CPC type slight curvature that would complicate construction. A wider target rectangle (Wo) with larger and multiple cookware may extend the latitude location range to about 30 degrees + for vertical kitchen wall reflectors and seasonal applications. Latitudes with 30 degrees + north and south cover an extensive global area and huge populations. However the site latitude locations need TRW solar engineering to specify reflector shapes and inclinations. TRW TEST STAND studies - All dimensions thus far are preliminary guesses in order to study construction feasibility. In fact, the TRW Test Stand dimensions may be reduced when based on solar engineering. Final dimensions would be based on optical-thermal engineering analysis for selected cookware target(s) and regional latitude specifics.

*{{NewOct21}}'''October 2021: Bamboo CPC solar cooker kitchen studies for Auroville region''' - The 32 degrees ½ acceptance angle truncated CPC (Rapaka Oct. 2006 p22) is inclined about 12 degrees south towards the equator for the Auroville area latitude location. The CPC trough is inclined similar as the solar bowl. The horizontal line from B on the left parabola segment to C’ on the right parabola segment is Wo (CPC width outlet). The horizontal line from A on the left parabola segment to D’ on the right parabola segment is Wi (CPC width inlet). An asymmetric truncated CPC is defined for about 12 degrees locations. ''Rapaka, E. V. K., Report No.3: Study on the optical and thermal properties of a compound parabolic concentrator with and without end-wall reflectors for Pondicherry region, Oct. 9, 2006, Department of Mechanical Engineering, Pondicherry Engineering College, Pillaichavady, Pondicherry, INDIA.'' CPC expert solar engineers may advise differently, however the differences are likely to be small angular differences, and the presented preliminary CPC characterization is sufficient for preliminary design of reflector facets and bamboo structure.

An intention is for large quantity production with bio-plastics and in-shop mirror tiling. An aim is to produce prototypes with ferrocement or other suitable prototype materials. Cookware sizes determine door clearance dimensions. A nonimaging solar concentrator may work well enough for a few cookware volumetric targets, for example, three HotPots TM in a line and two all-glass ~4”x 1m evacuated tubes (GoSun, etc.). Dimension E is tall enough for upward door swing clearance. A thru-wall solar cooker has significant house plan and site design solar access factors, complicating house cluster and multi-story design.

Joel Goodman is a research architect living in Wisconsin, USA. After a few solar cooking experiences in the 1970-80s, he began studies of small-mid size solar kitchens using built-in fixed ovens (2003), inserted solar box cookers (2005), and augmented with building size nonimaging fixed reflector troughs with adjustable end reflectors (2007)(2009).

Because of outgassing concerns from materials (insulation, glues, etc.) inside of augmented box cookers, and box cookers take up space in kitchens, mid-size kitchen studies began with thru-wall greenhouse type (HotPot, etc.) ovens (2006), and recently for small houses with thru-wall greenhouse type ovens combined with improved cook stoves, revealing house plan and solar access planning requirements. Additional studies are for exterior furniture fixed reflectors augmenting box cookers.

  • May 2023: TRW small low-cost masonry house in the tropics studies - A TRW configuration favored at this time for small masonry house studies is an ordinary-CPC type funnel-box with horizontal inlet aperture, flat trapezoidal kitchen wall reflector and vertical E/W portable reflector. Cookware options in the funnel-box are placed on a ‘square’ reflector plate that defines the cookware door width and associated lintel. An option is a temporary transparent horizontal unsealed cover glazing on the funnel box inlet. A TRW with a large cookware door would coincide with a main TRW characteristic that is: large, heavy or cumbersome cookware too inconvenient to carry outside to a solar cooker in bright sunlight may be used by cooks inside a TRW kitchen. Cookware options that fit thru the door and fit on a ‘square’ reflector plate include: a large diameter cylindrical cookpot, multiple smaller cookpots, and a cubic black metal oven. Aluminum or flat glass mirror CPC-type reflectors are in the funnel-box. Flat glass mirror reflector tiles forming a trapezoidal shape on the kitchen wall above the cookware door are being considered. The incline of the trapezoidal reflector is influenced by the latitude location. Construction materials and methods could influence cookware door size and TRW funnel-box shape e.g., Compressed Stabilized Earth Blocks (CSEB) standard shapes and sizes.

  • September 2022: TRW Kitchen Wall Reflectorก TRW kitchen wall reflector details depend on the kitchen building wall optical shape related to latitude location and construction materials and methods. For example, flat glass mirror tiles on masonry, ferrocement or wood wall parts. A TRW kitchen wall shape may be vertical or near vertical to avoid overhanging reflectors near about 23.5 degrees latitude (e.g., about 17-27 degrees); and sloped near the equator (about 0 จC 15 degrees from vertical) with possibility of nonimaging one-sided CPC type slight curvature that would complicate construction. A wider target rectangle (Wo) with larger and multiple cookware may extend the latitude location range to about 30 degrees + for vertical kitchen wall reflectors and seasonal applications. Latitudes with 30 degrees + north and south cover an extensive global area and huge populations. However the site latitude locations need TRW solar engineering to specify reflector shapes and inclinations. TRW TEST STAND studies - All dimensions thus far are preliminary guesses in order to study construction feasibility. In fact, the TRW Test Stand dimensions may be reduced when based on solar engineering. Final dimensions would be based on optical-thermal engineering analysis for selected cookware target(s) and regional latitude specifics.

  • July 2014: Thru-wall solar kitchen building or trailer with vertical oven door diagram. A thru-wall solar kitchen building or trailer has a vertical oven door (0 in Fig A); and reflector parts (Fig A): 1 is a reflector wall above the oven door; 2 is a box with horizontal or inclined inlet aperture (unglazed or glazed); 3 is a ridged- pyramid base/bracket; 4 is an E and W end adjustable or repositioned at noon; and 5 is the other side of a two-sided trough. Cookware targets (Fig B)include: w-1 roaster pots; w-2 HotPots TM; and w-3 all-glass evacuated tubes. Multi-tube racks rolls/slides in-out thru the oven door into the exterior cooking zone. A five tube rack is illustrated in Fig. C. The tubes are horizontal or near horizontal.
  • July 2014: Thru-wall solar kitchen with multi-tube racks roll in-out. Thru-wall solar kitchen with multi-tube racks roll in-out thru doors into the exterior cooking caustic zone, so that batch after batch can be cooked in a day. The multi-tube racks are within the volume of the exterior nonimaging reflector boxes, avoiding wind, and so that E and W end reflectors (repositioned at noon) flapping in wind gusts could not damage the tubes. The tubes can slip out of the racks for ease of tube cleaning.

Double hung window cooker 2, Joel Goodman, 3-4-14
  • March 2014: Converting a sun-facing double-hung window wall for non-snow season cooking and baking. The lower window part becomes the cookware doorway to the exterior concentrating reflectors. The window width influences the inlet size of a reflector ‘box’, securely attached to the exterior building wall. Roof overhang and gutters can limit the height of the upper reflector fixed to the building wall around the upper window part (above the box). The reflector ‘box’ would be removed for the snow season and the reflectors on the double-hung window could be removed as well for daylighting and passive cold season heating.

  • September 2013: Thru-wall fixed non-imaging reflector concentrator for ovens, cookers, autockaves, etc. A thru-wall fixed nonimaging (NI) reflector concentrator for ovens, cookers, autoclaves, etc. may be a lightweight for the most part attachment to a house or trailer wall. A NI ‘box’ has four creased aluminum-reflector elements attached together, secured to a square based two-angles pyramid-reflector(with grill posts) supported on a bracket(s) structured to the wall. Augmentation is with fixed reflectors attached to the wall, and E and W repositioned reflectors at noon with wind fail-safe design.

  • September 2011: When a thru-wall cooker counter height is higher, 36 inches/ 915mm above kitchen floor level, and the outdoor ground level is lower, 24-36 inches or more below the kitchen floor level, a more substantial construction is required to support the fixed reflector concentrator, possible with an integrated small storage space/room. And a higher rainwater drain permits water storage with a higher gravity flow.

  • The adjacent illustration of a partial house kitchen plan illustrates orientation and solar access requirements for a thru-mirror wall greenhouse type oven. The top edge of a nonimaging fixed reflector can align with different wall and roof house construction types and shapes.
Various fabrication-construction methods for a chair-size thru mirror wall oven nonimaging reflector concentrator include:
  1. Masonry substrates (compressed stabilized earth blocks, fired bricks, etc.) for gluing flat laminated glass mirror segments.
  2. Bent metal reflectors bolted to a center concrete pyramid with glued reflectors.
  3. Prefabricated injection molded plastic substrates for adhering reflectors.


  • December 2010: Joel has provided some conceptual ideas for incorporating thru-wall solar oven, and solar still installations.
