We are all familiar with how batteries power laptops and Priuses (Prii). But could batteries also be used in devices such as televisions to help improve energy efficiency?
It’s just a random thought, based around an idea I’m calling ‘timeshifted energy‘ or ‘energy harvesting‘. In simple terms it’s about harvesting energy at a more efficient time and in a more efficient way, siloing that energy in batteries, and calling on it to replace (or supplement) energy-draw during peak use.
Simply by drawing energy in off-peak times for use in peak-times has its benefits. But what really interests me is whether there could be energy saved by harvesting over a longer period (eg. 20 hours while the device is idle), for a use-period of say 4 hours?
I have a feeling that the law of conservation of energy is probably being violated in that thought process somewhere. And it wouldn’t be my first run-in with that particular law. Plus there will be some energy loss around the storage/retrieval process. Nevertheless, I like the thought.
