Keep your morning java hot with some busy mouse moving

There have been a gazillion questionable USB powered devices designed for doing things like heating your morning coffee. But why suck power from your computer's power supply, when you can harness the movement of your mouse to provide the required juice?

This design has induction coils built into the mouse and mousepad, which generate enough power to heat up a pad under your beverage. I just wonder if your morning joe will get cold if you start typing a long blog post on the keyboard.
