Like this guy said in his other video, just collect some old projection TV's for free, take them apart and see what you have. They will all help you cook, some better than others though.

Maybe this is what you are looking for Manny, there are different lenses and you want one that will focus the light and heat into your box oven.

Never doubt that a small group of dedicated people can change the world, indeed it is the only thing that ever has.

Doh! Guy, do you know how many big screen tvs I've passed up at the dump? Seems there's almost always one there. I'll have to keep my drill in my truck from now on when visiting the dump.
I can't believe how fast that beam can start flames when you have a good focus. That's got to be the ticket, there!

This couple have made it an art form. They even cooked their Thanksgiving Dinner using solar. Admittedly, they are in Florida, but it shows the potential of the system.
No matter how many mistakes you make or how slow you progress, you are still way ahead of everyone who isn’t trying.

Manny, I was shocked at some of the temps he was getting with those lens, he was talking about smelting copper! 
That is truly amazing to me. I put an add on Freecycle for a projection TV, but its like a Taxi, when you really want one there are none around. 
Graham, those folks are dedicated to solar cooking, they walk the walk as well as talking the talk. 
Their set up are truly great, they had all the options working for them. Bottom line is, it is practical, it can be done, it does work, it saves energy, it saves money, it saves the planet, the draw back is that it takes more time to cook supper than we as Americans are used to taking. Oh, another draw back, it does not work in the rain,
