I have to ask, what is the difference between the winner (solar cooker) and the same thing (in thousands of variations) that have been made by the Boy Scouts for over 30 years?

I "invented" this in 5th grade with my science class. If only I'd known it could be worth 75 grand...

The ceiling tiles are pretty ingenious.

The idea of a solar cooker box has been around since at least the 1960's. I'm sure the "inventor" will be quite willing to collect the prize money.

er... I learned how to do this in the boy scouts. This isn't anything new.

Yeah but none of you have actually done anything with that simple piece of knowledge... or have you?

People the world over cook in the morning and early evening mainly and indoors so the solar cooker is unlikely to be a success. As many of you said it is nothing new.
To be used you need to add a heat exchanger. ie the inner box except for the pot space is filled with a heat absorbing material. Ideally light weight and local. During the day the heat exchanger heats up in the sun when the pot of food is added in the evening it rapidly heats up the pots contents.
Now that is worth USD 75k.

Another box can be used as a heater in the cool nights.
Some other smarty may be able to add another device to create cool water.

The pill that reduces cow flatulence is an interesting idea.

Livestock are responsible for 18% of greenhouse-gas emissions worldwide, according to the U.N. -- more than all the planes, trains and automobiles on the planet. Why do the politicians focus on cars instead of cows?
