Solar oven can reach 290C

The manufacturers of this solar powered oven claim that it cooks a meal in as little as 20 minutes, even in overcast conditions.  It can reach internal temperatures of 290C.  It weighs less than 2kg and permits baking, boiling and frying.  Furthermore, it keeps food hot through the evacuated tube technology which is in essence a giant thermos. This means that when spotty clouds arrive, the tube will remain hot and steadily cook between sun-breaks. 

The UK price is GBP227.
