Energy harvesting is essentially heat reclamation. This makes for a trivial smell test for claims such as these: Think about how much heat is generated as you discharge your phone battery. Now imagine how long it would take you to generate that same amount of heat by swiping on your screen. Cars, for instance, generate a LOT of heat when you hit the brakes. This makes them an excellent target for energy reclamation. Now if they can reclaim the heat radiated from a CPU/GPU, that would we worth talking about.
