You're probably thinking WTF, but this is actually the new hot box that will be used during the testing of PSU's.
It's still not quite finished but the long and short of it is the controller at the top regulates the temperature inside the case by switching on/off and adjusting power going to the 300w ceramic heating element at the bottom of the case.
The tinfoil is there to reflect the heat and prevent the outer casing from getting too hot.
