Running the math suggests 0.1 mW. Which... the specs of many uCs I play with can theoretically drop down to 100uA or less of current (especially if I have capacitors to store energy while the uC sleeps). But ugggh. This won't be easy to design around. A lot of capacitors will give you 10uA of leakage already. Assuming 3V uCs, that'd be 30uW of precious energy just in leakage current. I think most people would rather use a AA battery. Is it really that big of a deal to replace the AA batteries every 10 years?
