Solar Barbeque- Green You Can Taste!!
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, 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.

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.

Low cost dish utilizing a waxed cardboard backing for use in developing counties. Provides
app. 1 KW of thermal heating for water purification and cooking needs. A Better Focus is willing
to provide this technology at no cost to developing countries, and train local residents how to
construct and use this dish.
A Better Focus Co. is willing to provide this technology to qualifying NGOs
and other organizations that promote the use of solar cooking in
developing countries. We have developed a dish utilizing the lowest
possible cost of materials. Technology and training are offered for
in-country manufacturing.
