INVENTION OF> a solar powered mug which heats up the water in it.OWN COMMENT> I like the best the very top one as it is stronger and the mug is visible.
It works better than others on the smaller scale.
I have found mugs which are traveller's accessories and heat up water once plugged to the plug in the car. Is my inevntion invented already?
What is important is that my mug doesn't have a wire and is for home usage.
Any comments?

I LOVE the first one! I like the solar cup idea. That is clever.
