It's a good idea, but it's not a new idea - I was using one of those in Australia over 10 years ago.

Ive seen them too but how will the conservatives take it?

Good ideas are good ideas but some people seem impervious to them.

I've never seen one before, anyone got any plans on how to build one?

How to Cook with the Sun

cool idea but if it rains your screwed

 

[gregorach]

Well, yeah - it's mainly for use in climates with reliable sunshine (of which there are many). Not much use in Scotland...

I have baked a cake in a cardboard box, lined with tinfoil with 2 rods shoved through it as a shelf for the baking tin to sit on. Bung some hot coals in the box, close it and wait - job done...

Is this not the wrong way round ??

lol...wow...what is the cook time on this. I have a feeling I would go nuts using an oven like this.

From the picture it looks like the foil on the flaps of the box reflect the light into the box where it's converted into heat by the black inside of the box. The heat can't escape becouse of the glass, as light can go through but hot air can't.

It's just sick that he won 50,000 pounds for something that made school children has already made and is in many hippy/alt energy/survival books.

Imagine winning 50,000 pounds for reprinting the Bible, original eh?

Your right, its by no means a new idea, nor is it the best solar cooker I have seen.

Its probably the cheapest....

He deserves the money if he can get it accepted by the people who need it.

I would say the prize is for a reproducable idea. The idea is not new but taking a simple idea and turning it into a massed produced solution is the real point.

Take two boxes, bit of foil, paint and some kind of see through lid. done ...............
Not really good enough instuctions to provide cooking facilites for an entire village.

Make enough for a village ( or 100 ) at a price they can afford and we have a winner.

My scouts have made pizza that way too.

The Cardboard oven in question is often called a conservation oven by Scouts.

Not easy to cook a load of mealie meal in one?

I'm guessing that a solar cooker in the U.K. is about as useful as a bikini in the arctic. Hey, I could be wrong on both counts!
