The Sundiner–A Groovy 1960s Era Solar Cooker:
Backywards beekeeper Dennis of The Buzz in the Dale, was nice enough to gift me his vintage Sundiner solar cooker that he found at a garage sale a few years ago.
Resembling a cross between a portable 1960s record player and a satellite, the Sundiner is compact, light and easy to carry.
A built in thermometer lets you know when you have hit cooking temperatures. The unit is so efficient, that when I set it up at noon it hit 350° F within minutes (in February!).
The Sundiner has one big disadvantage. There’s only enough space in the business end to fit a 9 inch square shallow baking tin. And that tin, depending on the time of day and year, may be at a steep angle. Thus the Sundiner is more of a solar grill–anything liquid will ooze downwards and make a mess of the difficult to clean, unidentifiable space age insulation material. Grilling is really not the best application of solar energy–you lose the smoky flavor and grill marks you get with fire–which is probably why the Sundiner never caught on. More recent solar box ovens that I’ve seen, both commercial and homebrew, have shelves with adjustable angles, making it easier to use them as crock pots.
Nevertheless, I admire the efficiency of the design–the legs also double as a handle and the panels unfold and snap together in seconds. It’s easy to aim. The instructions are even printed on the back of the panel that covers the reflectors.
More info via the April 1963 issue of Desert Magazine:
Here’s a new product that suits desert living as few others can—it collects and concentrates the heat of the sun and allows outdoor cooking without fuel or fire. They call it the Sundiner. The technical description is “Solar Energy Grill.” Sundiner is a compact unit, 17-inches square and 6inches tall. Fold-out mirrors are metalized Mylar plastic, supported by polypropylene holders. The mirrors focus the sun’s heat on the lower section of the cabinet, where heat slowly builds up to a maximum of about 450 degrees—plenty to cook with. Directly below the apex of the mirrors is an oven enclosure. Plastic foam insulation and a pair of glass plates prevent excessive heat loss. The solar energy grill works in this simple way: point the mirrors toward the sun for a few minutes until the right temperature is reached (built-in heat indicator dial) and pop a tray of food into the oven. There is no fire or fuel to handle. Sole source of cooking stems from the collected, concentrated rays of the sun. Here is a sample of how long various meats take to cook: Hamburgers, franks, and fish, 15 to 20 minutes. Steaks and fillets, 20 to 25 minutes. Quartered chicken, 25 to 30 minutes. Temperature variations are possible by turning the Sundiner toward or away from the sun. The advantage of the Sundiner is that it can be used as a safe substitute for a fuel-fired stove on beaches, parks, decks of boats, and other restricted areas. Carrying handles are standard. The price is $29.95. From Sundiner. Carmer Industries. Inc., 1319 West Pico Blvd.. Los Angeles 15. Calif.
