The tale of a potent gadget...

Its daily output keeps rising 
plus its enormous capacity
fells many.

The fare varies...
Toasted flowers, browned leaves
scorched fruits, scarred trees,
sizzling sand, wrung out minds.

The functioning goes on,
uninterrupted.

The clues ...
A gigantic oven.
The Sun's Magnum Opus.

A heat wave.
