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.
