| Typical Setup- Concentrating dish has a focal length of 8-10 feet, resulting in a hot spot of app. 1000F. The cooking surface is usually elevated |
| Insulated Pan for cooking brats, burgers, steaks, boneless ribs. Comes with a diffuser plate that spreads out the solar heat for an even cooking surface. (shown with wind cover) |
| Freshly Baked Bread from the inverted oven |
| Inverted oven for baking bread, cooking roasts, stews, etc. On windy days a transparent cover lets the concentrated solar energy through, but keeps the wind out. |
| Roast Beef and oven bag just removed from the inverted oven |

The Hot Spot concentrating dish is essentially a focusing "helostat" like those
utilized in central receiver solar power stations that generate electricity. The
dish reflects the sun's radiant energy from it's 45" diameter, and focuses it to
a 4"-6" diameter spot of highly concentrated energy. This energy can be
easily directed onto any cooking surface. Temperatures of over 1000F are
easily achievable on a sunny day (see specifications). Slight adjustment of
the dish is required every 15 minutes or so as the sun's position changes.

Dish Construction- A near-perfectly round and flat dish forms the basic
structure, over which a high quality reflective film is stretched. A hand
vacuum pump evacuates the cavity formed between the film and dish,
causing the film to deform into a concave mirror that focuses the sun's
energy at a distance of between 8 and 10 feet.The dish will hold it's
focus for several days. A tripod stand is provided, with one telescoping
leg for elevation adjustment. A plastic lined cardboard film cover is
provided to inhibit punctures during handling, and also to prevent soiling
of the reflective film. The dish is extremely strong, yet weighs only 8
pounds.
Cooking Accessories- A number of cooking accessories are available for
mounting to a simple pole stand. Many people modify an existing
umbrella table by drilling two holes in the pole to accept a peg-board
bracket for holding an insulated barbecue pan or wire basket, a
teakettle, or other cooking accessory. An inverted oven is by far the
most efficient method of capturing and holding solar energy. Our design
again utilizes a top-of -pole mount, and is capable of baking bread,
roasting chicken, beef, or pork, and also cooking chili or stews.

"I WANTED TO SHARE WITH YOU MY SUCCESS WITH THE SOLAR COOKER THAT I GOT
FROM YOU.
IT HAS DONE A GREAT JOB COOKING BURGERS, BRATS, HOTDOGS, CHILI, SALMON,
CORN ON THE COB, COFFEE AND MARSH MELLOWS USING ONLY SOLAR ENERGY.
WE DISCOVERED THAT WHEN WE TAKE THE SOLAR COOKER TO FOOTBALL TAILGAITING
EVENTS, BLOCK PARTIES, AND CAMPOUTS THE SOLAR COOKER BECOMES A
“MAGNET” THAT DRAWS IN BOTH ADULTS AND CHILDREN.
EVERYONE WANTS TO SEE HOW IT WORKS
THANKS AGAIN FOR YOUR GOOD WORK"

morning, before moisture lifts from the ground to make haze and
