Idea for Turning Infinity Bakery Solar Oven Prototype into Solar Reflective Heated Folding Shelter

Yesterday, I came across a UK Cambridge Uni team, who in 2014 Designed a solar oven  HERE

My basic idea is to use similar functions, but turn it into a shelter by having 2 facing curved reflective sides that move to form a roof at night for a shelter. During daylight sunny hours the roof folds down to heat a plinth like in the Infinity bakery.

If a bakery is not required, ir could heat water or soil / brick blocks to store heat for the cold night ahead.
Edit: perhaps this plinth could form a  work table / bed base.

2nd Edit: Having thought about the design for a few hrs, I cannot work out how to  have 2 curved reflective panels on one pedastal, so it's perhaps best to stick with one & have a seperate , removeable panel for the shelter walls. Otherwise use 2 units side to side

Mk 1 Ship Lap Type Wall Cladding With White Board Edge Off Cut (WBEOC) 

Strips are fixed with 3.9 screws to Composite Door Edge Strip (CDES) uprights & cross beam.

 I experimented with Lumberjack PU glue to try & seal joints, but the gap was too large. Silicone sealant may work / alternatively coat back with expanding foam to seal & insulate more.

Discussion was had re: whether gap for ventilation (like louvre shutters / doors ) may be useful in hotter climates.

Edge with mdf core at end & sides is exposed to rain. We laft a test panel in Uk weather for a yr & it expanded only slightly at edge. It appears that the glued plastic & polystryrene  / foam composite keeps it in place.

Coating the back edge with paint if left exposed would be advisable.

however, the corved edge may trap water allowing it to settle deeper inot the mdf. A drop of paint or white silicone sealant may stop this

few screws added (sealed with silicone) to stop expanding foam pushing sheet & beams apart



closeup of end screw, perhaps should have washers

closeup of middle screws, perhaps should have washers

Scrap Polystyrene put in 2 parts of panel to save foam (other part left clear as its the window)



Polystyrene forced  into ridge gaps to stop expanding foam escaping into window space



Expanding foam applied , along with one scrap panel of mdf / polystyrene



Poly appears to stop foam creeping / leaking

60cm wide Turkey size aluminium kitchen foil applied . I used this as it was the cheapest light reflective, fire resistant material I could think of .

This could be an interior finish or see 2 pics below
for extra panels

Close up . 2 strips of foil



Foil applied the other way on smaller part of panel


If required it can be covered in plastic panels, though more insulative, it adds more expense / weight
