I think it is really cool and very green. I can see it being used where there might be a power outage due to a storm and/or power lines being damaged. Being portable, it would be great for camping.

Thats the key for developing nations ....Gimme it for less than 200 USD, and I will buy 5 !

How does a guy clean this, and is the tube made of glass ? looks like it's custom built to cook a snake, a great idea for third world countries. Throw another snake on the barbie mate.

@ Atul: the company gives away one over for each five purchased and has a plan to work with developing countries.
I own a Solar oven (the original Sunoven) but will probably buy this one for backpacking. It also works to easily make water safe to drink.

How about using it to run a Sterling engine and generate electricity?

I have a Solar Flare: Parabolic Cooking System, cost, $70. It doesn't cook much (a quart) or fast (2-4 hours) or in cloudy weather. It blows away easily and must be anchored, which is a bother. It requires disassembly for mobile use.
I wish I had waited for the GoSun Stove and paid the extra $150.

@ Jay,
If snake is not on your menu, try a foot long hotdog, salamander (the amphibian) or a baguette.

Looks neat, until you get a few kms into the wilderness with no backup gas stove - left it in the pickup - and get a few very cloudy days! "I thought I heard you say this would be fun!!!!" "Yes dear" "No dear"

At that price it should include a solar-powered rotisserie motor driving the cooking tube (fully sealed off so it will spin - slowly - without spilling...) Then, make it large enough diameter to slide in a pork loin (or a healthy section of Anaconda for Jay Finke above) and it'll roast up juicier than anything! Slap on some barbeque sauce, with pickles & onions on the side, and YUM! :-)

@ thk - MzunguMkubwa I don't see myself cooking on one of these anytime soon, if ever ! and I enjoy my T-bone's cooked over coals with oak or mesquite. I hear the baby turtles have been plentiful at the beach this year, maybe they would be good on this type of grill, or manatee ?
