Anodise aluminium lumps and pour water on them.

With your roof covered in solar panels there isn't much room left, but with our new "Ridge Heat Lumps" that last bit of roof-top solar real-estate can be realised. Attach the long track to roof ridge and let the sun do the rest.

When making a hot beverage, prepare as many cups as required of cold water and press the "deliver lumps" button on the remote control. Next simply extend arm out of window with the catchers mitt provided and receive your requested number of lumps. Place lumps in cups and 60 seconds later enjoy !

For a small extra change we provide motorised accessories that will return lumps to the roof and solve ridge/window alignment problems.

Hot cubes Hot_20cubes

       Those hot cubes could well be better to put on the ridge rack. But since posting I've been thinking about "Ridge Hot Mugs" with thick bottoms and insulated handles and lip rings. I reckon they would get well above 100C sitting in direct sunlight.
