So, in the outside sunshine ... if you set your Solar on a cold drink cup, and the sunlight was directed on the top panel. Would it run faster ?

Yes I believe it would run faster due to the greater temperature difference.

I forgot to say when using a cup of hot water/tea/coffee or the usb warming disc the bottom plate will be the hot side so you would flick the flywheel the opposite way. Much the same if you ran it on an ice block as the hot side is reversed.

I certainly recommend Kontax’s solar models as it is nice to use the sun to power them (when it decides to come out!)
